A mod you say? Just what the hell is that? Luckily Urban Dictionary has been defining anything your parents don't want you to know since 1996 (ish)

1. Hey, did you see the Silent Hill mod for HL2? It looks good.
2. Someone report this Goddamn troll to a mod.

This thread is a collection of what I consider the greatest mods for PC games. Am I missing your favourite mod? Post up whatever you want and I'll be sure to put it on the front page so all can see it's magnificence. :srsface:

Mini- tutorial

Most HL2 mods found on this page can be installed simply by running the installer. Really, it's that simple.

For some portal mods, or in the case of Union, you must extact it, then drop the files in your steam/steamapps/[yourname]/half-life 2 episode 2/ep2/maps folder (or modify for preferred source game), then to run it first enable developer console in keyboard advanced options, then press ~to bring up console then type "map union01.bsp" (or something to that effect, the console will autocomplete the line so press up/down to load up the correct map). After saving, you can simply load up the save without any console business.

L4D mods come in two varieties, .vpk files and maps (.bsp). Any newer map.campaign should be .vpk, all you have to do in that case is double-clock the vpk file and it will install for you, then in L4D click extras and enable the content. When choosing map there will be an option for non-stock maps, click that and select the map you want. .bsp files install in the same way as the previous paragraph.

Multiplayer Mods

Firearms: Source

Firearms:Source is a team based first person shooter, rooted in the traditions of the Firearms mod for Half-Life. Firearms:Source brings the best aspects of Firearms to the Source engine, and then takes them a step further. You'll see a host of familiar weapons and maps, but you'll find the streamlined game play to be faster, focusing on aggressive, skilled play. From nearly the moment you spawn you can expect to be engaged in furious action.

A multiplayer HL2 mod, not unlike COD4 with 30-some authentic weapons

Zombie Master

Zombie Master is a multiplayer Half-Life 2 modification, centred around a zombie-apocalypse, which throws all but one player in the shoes of human survivors. Pitched against a relentless tide of rotting flesh, they must scavenge for weaponry and equipment just to stay alive. But that one player, chosen randomly at the beginning of the round, is not bound by mortal restraints.

Resistance and Liberation

The goal of Resistance and Liberation is to realistically portray the events and actions taken by the 82nd Airborne during their stay in Normandy. Our initial release will follow the regiments through a campaign that mimics that followed by the men themselves. The campaign will begin with players dropping into Normandy in the early hours of June 6th, with the ultimate objective of capturing the town of Sainte-Mere-Eglise. From there subsiquent maps will include missions based on locations such as Montebourg Station, La Fiere, Carentan, and other key areas.


Synergy is a Half-Life 2 co-opertive multiplayer modification.
We have evolved from multiple mods (DC Co-op 2, Dev Co-op and Tim-Coop). This modification strives to give Half-Life players a true Half-Life 2 cooperative experience.
The mod features our own levels and the ability to play the Half-Life 2, Episode One and Episode Two campaigns cooperatively.
In addition, you can add more content by installing third-party mods, such as ROCK 24 and MINERVA: Metastasis, then playing them in Synergy!

Zombie Panic: Source

The basic idea of the Zombie Panic is to create solid game play that is based on a classic zombie outbreak scenario. The living dead are coming for the last remaining humans, and these survivors must fight them off and live through the day.


The world of Dystopia is a heavily technological future set in an urban jungle of over-industrialised cities and environmental devastation. The MegaCorps control most aspects of everyday life and are often a law unto themselves. They employ all means to gain the advantage over their competitors including hacking, deployment of assets, direct confrontation and covert ops. With access to the latest bleeding edge technologies and weapons the Corporations put profits ahead of anything else.

Goldeneye: Source

GoldenEye: Source is a modification of Half-Life 2, with only one goal in mind; to bring the memories and experiences from the original GoldenEye64 back to life using Source Technology. We want you to look at this mod and remember the first best multiplayer first-person shooter ever made. We are doing our best to bring in the opinions of the community to create a game that everyone is going to enjoy. But, we are not here to recreate the game exactly how it was in GE64, a lot of things have changed since they first designed that game, mainly in technology and gamers experiences. We are here to take the game even further but at the same time provide a lot of those fun elements that hardcore GE64 fans will enjoy. We've got experienced team members all across the board, from professional level, to amateurs looking to make it into the business working hard to make this dream a reality.

Age of Chivalry

Age of Chivalry is a total conversion for Half-Life 2 currently being developed by Team Chivalry. We are a close group of friends who are dedicated to creating a fun story driven multiplayer experience set in a fantasy world in the medieval ages. We are creating a fast paced and fun first person melee combat system that will take the player to a new level of immersion. The players will be able to take part in sieges, town raids and open war in a story driven game. Our goal is to let the players write the history of the game as the teams battle it out over a sequence of user controlled map cycles depending on the victor. We want to take the overall experience to a new level of fun.

Garry's Mod

This latest build fixes one definite crash bug, has decreased load times slightly. Most of the CS:S weapons are in there by default. Weapon selection menu has been redone since it was getting cramped with the adding of the new weapons. This version also adds NPC death notifications. When a player kills an NPC it will show in the top right hand corner just like when a player gets killed. As mentioned above the spawn menu has gone though some major changes. One cool change is that it now stretches vertically with your screen resolution. This should help people with more than 3 mini mods installed - you’ll have plenty of room now.

Gmod gives you the Source engine, a myriad of tools and an empty map. There is no set goal, you are set free to do whatever you want to. You can build obscenely complex vehicles, or you can simply pose the HL2 characters in naughty positions. It's up to you. The game is highly moddable, too, so if you want a prop/ragdoll, you need only look on the official forum, download site or google. This game will not grow old, there's always something else to do...it's up to your imagination to figure out just what that is.

Decadence is a story-driven multiplayer modification based on Valve Software's Source Engine that combines the personal relationship to characters and surroundings of single-player games with an adrenaline filled multiplayer experience. Decadence pits two teams against each other in a fight over territorial control. Each map is designed in stages to offer a more compact and action filled gameplay that puts focus on teamwork and strategy. Decadence is multiplayer with personality, where you play as one of four different characters. The character you pick is specifically for you and will give you certain weapons and other advantages, and you need to use every single one of them together in combination with your teammate to succeed. The environment will also be key to survival, providing cover from enemy fire as you advance towards their flag. Staying close to your teammate is vital in Decadence. They are able to help you in many ways, not only as an extra hand in combat, but they can...
2v2 multiplayer combat. It's ok, there's some balancing issues they need to work out but it's the 1.00 release. Servers are all a long ways away, all ~200 ping for me so I think it's just the modders and their friends with servers atm since they are all very similar ping. Only 2 maps for now, but it is excellent mapping, one even looks like it was done on Unreal 3. Not that unreal is better than Source, it just has a distinct look.


Ragnarok Arena Remastered

It's 1998. You've been playing sidescrolling platform games since what seems like the incarnation of computer gaming. Sure you've played Evil this, Earthquake that, but most games up until this point have lovingly involved a 2d plane. Then, games like Metal Gear Solid and Half Life come out. The face of gaming changes forever. You are happy.

It's 2008. You've been playing FPS games since what seems like the incarnation of PC gaming. Your three hundred dollar graphics card renders in multiple shades of brown. Your monitor can display 32 million colors of retina-burning blooming brown. You've been to underground temples, sewers and caves (brown), ww2 trenches and ruined cities (brown) and post apocalyptic wastelands (brown). It's time for a change.

A sidescrolling, platforming multiplayer deathmatch - A randomly dispersed armory of more than twenty classic and original weapons from across the history of fragging and levels that capture the true essence of a sidescroller: Insane and without logic.

Utilizing the latest Valve Source engine, Ragnarok Arena Remastered aims to bring you the latest and greatest in sidescrolling deathmatch gameplay. Featuring larger maps, vibrant graphics and crowd pleasing technologies that have been around since 2004, RAR aims to bring Ragnarok Arena kicking and screaming into the twenty first century. And best of all, if you own any Source game that supports the Source SDK Base; well, you can play RAR. No Orange Box required! And no longer is it a simple remastering, this is the sequel to sidescrolling insanity.

Forget your third dimension - Welcome to the Ragnarok Arena. Part II.

Arena Harder.
Ragnarok Arena is a shooter where you can only move in 2-d, but it's built in a 3-d world. You then run around and mow down as many other people as you can before you die yourself. Simple concept, great fun.


Not really a mod, since it'll cost money but built on Source


YouTube- NEOTOKYO Official Trailer

Mission Statement:
NEOTOKYO° is a first person shooter that aims to provide a visceral & realistic combat experience in a rich futuristic setting.

Background Story and World:
NEOTOKYO° takes place in and around a fictionalized Tokyo approximately 30 years in the future. Mankind has begun to fuse with technology. Government and corporate corruption have transformed Tokyo into a deadly dystopian nightmare. After a near-successful military coup by ranking members of Jinrai, the National Security Force (NSF) is formed - answering directly to the Prime Minister, it's mission is to investigate and eliminate all threats to Japan, both abroad and at home. The initial core of the NSF is made from an exodus from within the intelligence branch of the military. With this betrayal begins the war in the shadows between the NSF and Jinrai.
Neotokyo is a class-based multiplayer shooter set in the near-future. There are 3 classes, which mainly offer different comprimises of mobility, stealth and firepower. Despite the bland and cliche' classes, each does offer different tactical opprotunities, and discovering a "play" which works to their strengths is very fun. The mapping is very detailed, with no noticeable HL2 props re-used, gameplay is well-balanced and fun despite round-based CSS type gameplay. A must-download.

Minerva: Metastasis

[developer blurb omitted]
Minerva is a FPS mod taking place in the HL2 universe. You play as a ex-combine soldier, who was freed by your employer. Your life now belongs to her. She has sent you to a mysterious island which is under combine control. It is your job to find out what they are doing on that island

Interesting fact: the sole developer of this mod is now employed by Valve.

Playtime: 5-7 hours to the best of my recollection


Research and Development

Research and Development is a puzzle-centric mod for Half-Life 2: Episode Two, featuring an unarmed player but plenty of violent mayhem.

Looks like a great mod, pretty maps, interesting design and good ratings, full review once I play it.

WOW, that's all I can really say. I'm tempted to say this is the best mod I've played yet. It starts off as a collection of HL2-like puzzles, but slowly cranks up the pace to an epic finale. I won't ruin it for you, but you'll be impressed. The story is in the HL2 universe, and uses HL2-type puzzle objects, but in far more varied and fun puzzles than were in HL2. Length is 3-4 hours, and only 80-some megs too.

There are few new textures/objects/sounds in this mod, most of it is tried and true HL2 assets. The mapping is superb, very few glitches, there's even a few scripted events and camera break-outs. Seriously, this is so well-polished Valve could easily have made sections of this fit into HL2, just they don't have the creativity these guys put into it.

If you are by chance some sick Gmod lover, you will have incredible respect for this game. There's a lot of stuff in here that reminds me of some Gmod vids, taken to the next level.

I'm crossing my fingers for this becoming a series.


Nightmare House 2

In Nightmare House 2 you wake up inside an abandoned hospital with no understanding of how you came to be there, only a vague memory of the girl from Nightmare House haunts you. Soon it will be difficult to determine between a dream and reality. How long will it take you to realize that escape is not an option?
Nightmare House 2 is the sequel to the Half Life 2 mod, Nightmare House Remake, which is a remake of the HL1 mod Nightmare House. HL2: EP2 is required from what I can ascertain (lmk if otherwise). NH:R is included in the NH2 install, so no need to install it separately if you want to get caught up on the story.

The mod was pretty long, a much bigger undertaking than the single map NH:R. Graphics are great, very good polish, and not a single bug encountered.



Re-enter the Half Life Universe and revisit City 17 in the time before Freeman, in this fan made single-player mod. The Resistance is threatened by a decisive Combine assault, and as a wanted Resistance member you will need to fight to escape from the Combine's clutch. At the same time, a mysterious force is working towards ends unknown...
Another polished HL2 mod set in the HL universe. Escape from City 17 as the Overwatch starts to clamp down on resistance within the city.



Dissolution is a science fiction, single-player mod for Half-Life 2 that mixes adventure and action game-play. Set in the year 2089, in a universe dominated by a mega corporate entity, Xterrier, the player awakes in a hidden lab to the voice of the mysterious Wilson. Guided by Wilson, the player must make their way through the ravaged Xterrier 581c colony, making use of any and all resources they can get their hands on in order to survive, all the while attempting to piece together the events leading to the colony's collapse and their own identity.
An interesting HL2 mod. You explore a space station and attempt to find out what went wrong. It reminds me of Bioshock in a lot of ways. Graphics aren't ultra-detailed like a lot of other mods on here, but they do the job well enough, and the relatively modest mapping has allowed the author to make a much larger mod than is usually seen.


1187: Episode 1

Almost a decade after the Black Mesa Incident which opened up the portal storms you find yourself trying to cope with its aftermath. Creatures appeared which came out of what seemed to be thin air. They came without warning and swept the world. It is during this time that you find yourself in your apartment, alone for no apparent reason. You're been approached as in a dream by a man in a suit. Having no idea of what's going on all you can do is try to stay alive.
This HL2 mod is set in a time which has not been covered much, from the HL universe. It occurs after HL1, as the world is slowly consumed by aliens which randomly teleport in, and humanity is pushed back to fortified cities. The first episode is all that has been released so far, but it's on the longer end as mods go, with pretty good mapping and lots of different gameplay situations than HL2 (ie more than corridor shooting).



Slums is a short mod in the HL2 universe where you fight through City 17-style apartments. The mod is fairly short, but the levels are very detailed and make for very good combat. Story isn't there, as is expected for such a short mod (30 mins- 1 hr).



Slums 2 is out, he basically took his old mod and polished it. The combat is still great (ie. a challenge).



Slums 2: Extended is out. Same old gameplay, with a bit of length added on. Graphics have been improved greatly, it is quite an impressive work for two guys to make in their spare time. In terms of visuals, it is a far cry from what the original Slums looked like.


Riot Act

"Numbness and rage. Fright and anger. I open my eyes. Oh, well. My cell is pitch dark anyhow. "Block E1". I heard their inhuman voices. Lying on this cold metal bed, I stretch my arms along my sides. This must be the right posture to fit in a pod. I do not tolerate the idea of not being ready.
Yes, but ready for what? No, I won't give way to grief.
A squeaky sound... No, no way. It can't be true. The door opens, light replaces darkness. I will ask for a reason later. Now I have a choice to take. An easy one. I will run the hell out of here, whatever it takes. It's time to get a little revenge.
It's time to start my own riot act. "
An excellent mod, one of my faves. Nova Prospekt environment, but combat is very well-done and levels are pretty.


Attempt to Survive

Gameplay features:
No weapons
No enemies

What will you do, when you are scared, alone, and your hope is dead?

An cool adventure mod made in HL2. ~1 hour of gameplay, excellent visuals, interesting storytelling, all that good jazz. Well worth the download.



Curse is a puzzle/combat game in first person perspective. Taking place out of the HL2 universe, you are in an ancient Egyptian complex, finding your way out. Tons of new textures and objects to be created from scratch, so t will look very different from every other HL2 mod you've played.

Has been released, go download episode 1 here



Rock 24

Rock 24 takes place on an abandoned Cliffside prison.
The prison is situated on the side of a sheer cliff face meaning the only real way in and out is by air. The combine have moved in to the facility and are re-using it as a place to hold rebel leaders and other important Rebels.
Gordon is required to infiltrate, free the Rebel leader and hopefully escape from the facility alive. Unfortunately the prison is rapidly deteriorating around him and there isn't much time.
The blurb explains it quite well, so this will be short. The mod's length is about 5 hrs. Story is solid, mapping as well, but the voice acting could use some work. This mod really covers all the bases and delivers a great, engrossing experience.


The Citizen

The Citizen is set parallel to the events of the original Half-Life 2. The player takes the role of an ordinary man, pushed over the edge by the oppressive regime controlling his life. His home trashed, his family dead, The Citizen leaves his apartment for the last time. He seeks new friends, and a way to help the human resistance to smash the iron grip of the Combine. What follows is a winding tale of betrayal, determination and grief. Many obstacles lie in his path which require a sleek combination of agility, stealth, intelligence, and sheer violence to overcome.

stop with those dirty thoughts

The mod story does not consider events in Half-Life 2:Episode 1. After explosion of citadel, G-man immerses Gordon Freeman in stasis, but after a while deduces it from there for the new mission. The target of this mission is penetration into a citadel which is in City 18 (the city located near to City 17). In this citadel there is a teleport in Combine world. Using this teleport, it is necessary to get in Combine World and to destroy their leader.
Story is there, but it isn't as involving as some other mods. Great maps, long length (~4 hrs). A bit lacking on puzzles and story but solid nonetheless.


Cinematic Mod

Cinematic mod is a mod which improves the visual fidelity of HL2/episodes. HL2 and Episode 1 are ported into Source 2007 engine and many textures and objects are replaced with high-resolution ones. Much more computer-intensive than HL2 is, 64 bit operating system is required for it to run properly, 4 gb or more ram as well. A 8800GT or better will run it well, but more than 512 mb vram is recommended. The newest version is v9.51 . To get V9.51, you must first download CM9 base. You can download CM9 HD-addon for better character models. Then you must put the v9.51 hotfix ontop of it all. Requires around 20 gb of hard drive space.



The atmosphere in the original HL2 game was both interesting, and terrefying, and that is the driving force behind our choice on creating a modifacation on that enviroment alone. All maps from this modifacation have a very similar kind of feel of atmosphere and gameplay from the original Ravenholm, but with an different and expanded story, and many new locations. So, you will find yourself battleing many more Zombies, Headcrabs, and more.
[spelling errors left intact, english is not the developer's first language]

Ravenholm is a mod for those who can't get enough of the Ravenholm chapter in Half-life 2. You are trying to escape from Ravenholm, which is zombie-infested (duh). This mod is quite long (~6 hrs from what I remember) and has more emphasis on combat than HL2 (as opposed to puzzles or story building). Not that it lacks them, it has plenty of head-scratchers.

Now the bad. It can get to be a bit tiring, the scenery doesn't have a great deal of diversity for such a long mod. (there is more than Ravenholm streets and buildings though). It can also be frustrating to find your way out of an area. A tip: if you can't find your way, think vertically and start stacking boxes to use as a staircase.


City 7: Toronto Conflict

City 7: Toronto Conflict, is an action packed Half-Life 2 mod with a variety of unique levels and game play. Explore what has become of City 7 in areas like Dundas square, Eaton Center , Mel Lastman square, St. Michael's Hospital and TTC system under the Combine rule. This version features Gordon Freeman as the main character, stuck in Toronto due to a teleporting accident in Kleiner's lab. Try to escape this war torn city by finding any type of teleporting technology and send him back to City 17.
See Toronto like FPS_Doug does! Exterminate combine scum from teh best city ever.

Not much story, but good mapping and attention to detail. I was around 2 hours in when my computer broke down, so it's longer than 2 hours.

Something funky with the download from the moddb site, I'll post the one I used later.

Download here:

Casualty Effect

What if everything that went wrong on "A Red Letter Day" was not caused by what you thought? What if your teleport ripped a hole in space and time? Now you must travel through time to correct the events and set right your past.
Haven't played, just posted it because it looked good.


The Island

The island is a singleplayer, first person shooter mod. There are no puzzles here, just pure, intense action. And who are your enemies? An army made up solely of zombies, particularly fast zombies, and their headcrabs. Where is this taking place? Any random island; the location is irrelevant.
This mod will be best suited to skilled action-oriented gamers. The mod is eight maps in length and includes many of the Source engine's advanced features and effects.
You are on a random zombie-infested island. Your goal, get the hell off of it.

A fun zombie blaster. ~1 hr long.



"The last thing I remember was our train being stopped in the woods. OVERWATCH told me I was needed for questioning, so they locked me in one of those cold pods and stuck me on the next train to NOVA PROSPEKT. I can still see my WIFE watching me drift away.

Now, here I am... Only things are not how I expected them to be. How long have I been unconscious? A few days? A WEEK? Something has gone HORRIBLY WRONG..."
Union is a short (45 mins-2 hrs) map pack in the HL2 universe. It is very well-done, and takes place in Nova Prospekt. You and a Vorunigant ally must battle your way out of the prison.



A short trip, an ode to the shotgun, and a game made to celebrate the ever-blissful gutfilled splash of shotgun + antlion. Made in two weeks, + another week of tweaking. Comments and criticisms appreciated. Note: requires Half Life 2: Episode 2 to play.
Intrusion is a short mod (30 mins-1 hrs) where you fight your way through an antlion-infested building complex. No story to speak of, but great fun nonetheless.


The Lost City

In single player mod The Lost City you should get out of the city grasped by Combine forces.
With it you will be helped by one of few survived insurgents.
The basic emphasis was done on study of maps and gameplay.

Missing Information

Missing Information aims to recreate Valve's original Half-Life 2 storyline found in Raising the Bar.

Zombie Stress

ombie stress is a Half Life 2 Single Player modification, which instead of giving you some complicated story or long winded puzzels to over come gives you what you want... zombies!

Removing the need for stories to interest you, this small mod is designed to just allow you to relieve some stress by giving you 3 different styles of zombie destruction with many weapons.

This mod is not aimed to be amazing, just a bit of fun. Though a lot of it is turning to be a turret frenzy but you can choose your game play. The machine gun and shot gun are pure favourites for pure slaughter and maximum stress relief.
Developer blurb sums it up well. You get a gun, zombies spawn. What to do...?


Half-Life 2 Old-School

You love the old fps, HALF-LIFE² old-school is for you !
Find every keys in each level, find some secret, kill everyone and push a big button to finish the level !


eXterminate is a FPS type mod in pure kill-everything-that-moves style. I'ts very similiar to the classical game Phobia II, with the exact same same point: Kill as many things as possible before you die.
The epitome of this section of mods. You spawn in a level, enemies are spawned, you get points for each kill.


Nightmare House Remake

Yes, the classic horror map is back with a modern, sharp new level design, plus a couple of new surprises. This tribute should hold you up until the next full 'episode' comes out

Note: You need both HL2 and CS:S installed to run this mod.

Good mod, perfect length to cover all of the modder's ideas, but doesn't do any concepts to death (heh) ~1 hr


Eh.. its OK

Prepare to have your retinas burned

Might be alright looks strange

More strangeness

Mission: Improbable

A Resistance listening post suddenly goes off-air and you are sent in to find out what happened to the original support crew and get the station back online. Your journey begins as a rowing boat coasts towards the landing point. Who knows what you will encounter, both on the way up to the tower and on your way down.
Another mod in the HL universe. Very nice mapping, decent combat, a short story to go with it. About an hour in length.

Nice panoramic shot:

Title might not be self-explanatory, so I shall explain

This section is for mods which are not yet completed, and yet still have something playable released. This might consist of the first couple chapters in a completely playable and polished state, or is could be a couple levels mishmashed together without any real idea of what you're trying to accomplish.

Eye of the Storm

Eye of the Storm. Picking up the story after John's escape from Ravenholm, you will visit new locations and meet new characters as you are taken prisoner by the Combine in City 24 and are reunited with an old friend from your resistance fighter days in City 17. Now he appears to be the key to unlocking the next chapter of your forgotten past.

Does it not seem there is a greater power behind the curtains?
EOTS is a highly-polished demo release. You play the first 30-45 minutes of the game. Levels are beautiful, and there are gameplay mechanics that break the same old "copy Valve" approach many mods use.

This is the sequel to a mod called Ravenholm. however, this mod is far more polished than its predecessor, so don't assume it's more of the same.




Altered Transmission

Every city left on Earth are under combine control, whether they know it or not. In some of these cities resistance have been observed. One may notice things are different in City 12.
Non-combine television was reintroduced.
The telephone system and thus the Internet were restored.
Half the Civil Protection are corrupt.
Thanks to the resistance in City 12, the Combine is slowly losing control.
In Altered Transmission the player arrives at City 12. Several forces are soon aware of his presence. As you probably imagined, the resistance has a mission for him: reduce Combine influence.

Black Mesa: Source

The upcoming mother-of-all mods. Aims to recreate the HL1 plot on the Source engine, the way that Valve would have if they had use of the Source engine when HL1 was created (ie. they are giving themselves some artistic license to change it for the better). Follow the link, watch the EPIC trailer.



City 17: Episode 1

Mod spanning in all of the Half Life world. You play as a Rebel named Jack with help of a friend throughout the game.
Much like in Episode 1, your main Goal is to get away from CIty17 as fast as you can. However the game plays out from a different perspective. That of a rebel. While having the same timeline of events in CIty17, the main game plays out in a totally different way from Episode 1.
You really need to check out some of the neat things these guys have done on source. There's an asston of pics in the link, and there's a really neat vid showing some of the stuff they have added (yes, you read right) to their customized source engine.



Curse is a puzzle/combat game in first person perspective. Taking place out of the HL2 universe, you are in an ancient Egyptian complex, finding your way out. Tons of new textures and objects to be created from scratch, so t will look very different from every other HL2 mod you've played.


Lost Hope

"It's approximately a hundred years from now... the aftermath of the Third World War.
Countries all over the world are suffering an economic crisis which has led to a dramatic food and water shortage. The countries that do have enough resources are under martial law, food and water are not being divided equally, consequently civil war has broken out.


8. September 1997, somewhere in Russia. 58 years have passed since living breath was felt in this place. You wake up in an abadoned tunnel, without even a name ...
Looks like S.T.A.L.K.E.R., smells like S.T.A.L.K.E.R., tastes like S.T.A.L.K.E.R., but is on Source. Whats not to love

More pics here


Update: Raindrop has moved to be an indie title. Hopefully it delivers.

Opposing Force 2

Seven Hours War aftermath... An year after the war that defined the fate of mankind. Set on an Earth that's slowly falling appart, you take control of Adrian Shephard, a marine who once fought for mankind... With the objective of eliminating a dimensional rift between Aliens... And humans.

The Citizen Part II

Set in and around City 17, "The Citizen Part Two" contains the final three chapters of our citizen's story. After the events of the previous two chapters, you find yourself rescued from the grave by rebels, among whom you are now a valuable asset. Taken to a makeshift field hospital, you recover in the hands of rebel medics. But the Combine are determined to crush the rebels out of existence, and the peace can't last long. You will face many choices, and how you decide to proceed will ultimately dictate how the story plays out for you. Some choices are less obvious than others, and require you to take initiative where you otherwise might be distracted. One way or another, it's time to take back the city.


Fedora is a Half-Life 2 Total Conversion focusing on an Indiana Jones - style atmosphere and puzzles. You're sent into a temple to retrieve an idol. Sounds simple? Traps, critters and rolling boulders might make you think otherwise.
The player takes the role of Philip Maxwell Fedora, last of the Fedora bloodline. It's been decades since the mysterious disappearance of his relatives - now 27 years old, Philip finds the notebook of his uncle Thomas. With it the last Fedora has the possibility to find them.

The Gate 2

Operation Black Mesa

Operation Black Mesa is a total Source conversion of Half Life: Opposing Force.
Half-life: Opposing Force is still an amazing game, although its not nearly as amazing as it was when it was released. Using the Source engine, the developpers plan to recreate the Black Mesa research Facility as it was seen by Corporal Adrian Shepard of the H.E.C.U.
VALVe Software originally had plans to port Half-life: Opposing force into the source engine (announced at E3 2004) much like they did Half Life: Source, but after seeing the results of Half life: Source the Operation Black Mesa devteam decided that it wouldn't be worth the wait, and thus took the task into our own hands.

The Tower

Yes, the world need you again. The citadel's destruction don't represent the end of the war, it's only the end of their supremacy. Somewhere, in the middle of the boreal forest, they prepare their riposte and this time, nobody can save himself.

The Tower is a singleplayer mod developed by me, Xitis, taking place in a giant industrial complex including many environments distributed in six chapters, with one to three maps for each ones. This mod is mainly based on the gameplay and level's atmosphere,and I don't expect to revolutionize by my storyline or by the level of difficulty.
Just had its first media release, so it's probably a while off still. Looks sweet though.


Looks wicked

Nice mapping

Pretty HL2 expansion type mod

Demo is good

Awesome and Stalkerish

Shows promise


Zeitgeist. A single player modification playing in the futuristic 1930s of a fictional time line. "... for the wise man looks into space and he knows there is no limited dimensions." - Lao Tzu



TEAR is a total conversion Single-Player modification to Half-life 2 which based on source engine. It takes player to the medieval world filled with zombies and other disgusting creatures.
The stroy:
Our main character Tabito is a travelling merchant in the lands of Mexiria. He decides to go a tavern in the town of Riverdale. There he gets in the middle of a fight, resulting in our hero being knocked unconscious. Believed to be dead, the tavern keeper decides to get rid of him but there is too much crowd on the street, therefore he throws him in the basement so he can burry his body in the night. After 5 days He awakes in the basement with a big headache and he can't remember anything of what happened. After he stumbles around for a few moments he hears a growling noise, unlike he has ever heard before. He then sees the terrible creature, something that looks like a human but with a big parasite on him that pierced tentacles throughout the humans' body...

This section is for mods that don't follow the same old thing the Source engine is built for (killing in FPS perspective).

Dear Esther

Dear Esther is part of a research project, creating experimental game mods, based at the University of Portsmouth, UK. The aim was to use Source to create something radically different from normal: an interactive story that dispensed with traditional gameplay and focused instead on an open-ended, semi-random narrative.
Dear Esther is a "interactive ghost story". Don't let that turn you off, just because there's nothing to shoot at doesn't mean it's gonna suck. In this game, you walk around, piecing together the clues that consist the story. Story, concept and voice acting are all top-notch. Length depends greatly on whether or not you take your time. It took me around 3.5 hrs, but I tend to lolligag about.


Ultra-late update: DE has been in redevelopment for some time as a HL2 mod, the resulting vistas are quite incredible. After winning some ModDB mod of the year awards, it has gone to a indie development.

A Corny Voyage

This is a racing game, but not like you'd expect. You control a kernel of corn and you have been eaten. You must race your way toward the circle of light before you are digested.


HL2: wiimote mod

Half Life 2 : WiiMote Mod aims to bring the new Wii remote technology to Half Life 2 while also allowing full customization of the wiimote input and offering new gameplay centered arround the Wii Remote!
I wouldn't be caught dead owning a wii, but it looked like an interesting concept


Crates and Barrels

Crates and Barrels is a single-player "minigame" mod for Half-Life 2. It is a unique mod for several reasons, most notably for what it is not: it isn't a shooter (first or third person) - it isn't an RPG, strategy, or adventure game - and it doesn't use the Source game engine. What it is, though, is a collection of mini-games which use the Half-Life 2 characters, objects, and textures in several simple and classic video games that are intended for a few moments of comic relief. Written entirely in Visual Basic 2008 and using Managed DirectX 1.1, it is a first for Half-Life 2 mods. You will need Half-Life 2 installed in order to play this mod, as all game content is loaded as needed during gameplay from the Half-Life 2 GCF files.

Portal: Prelude

Portal: Prelude, as its name states it, is an unofficial prequel to the game Portal. Its story revolves around the pre-GlaDOS epoch, even before she was plugged in. At this time, test subjects were monitored by real Aperture Science employees, whose work was tedious, lengthy and repetitive. This is why they decided to build a great artificial intelligence that could both replace them in these difficult tasks, and also take responsibility for many other tasks within the complex and compete with Black Mesa's superiority. All employees of the Aperture Science complex are now eagerly awaiting GlaDOS. Maybe even a little too eagerly, as the upcoming events will tell... This game is totally free. It offers a bit more gameplay hours than the original Portal, with 8 chapters, 19 test chambers, 48 challenges, 6 advanced maps, a brand new storyline and more than 400 lines of english speech with dozens of subtitles translations.
A great mod, can be frustrating due to the complex manuvers needed, but a good solid story and great mapping make this a must-have.

Portal: The Flash Version Mappack

Based on the Portal: The Flash Version (Portal.wecreatestuff.com)
This Mappack brings all of the 40 levels plus some more originals.
The story takes place before the events of Portal and shows you the enrichment center from another perspective.
This Mappack includes ALL 40 levels from the Flash version, additional bonus levels and features. All together, we've got here over three and a half hours of amazing gameplay.


- Based on Portal:TFV
- More than 40 test chambers.
- Level design similar to the original Portal style
- Level difficulty is balanced, like the original
- New gameplay elements, such as the Electric Floors, Crushers, Blue and Red frizzles from the Flash version
- Isn't a test chamber after a test chamber, much more than that.
- Awesome storyline that connects to the Portal and the Half life 2 story
- Epic moments.
- Boss battle.
- Epic ending.
- The longest custom map so far, at least as far as I'm aware.

*More info in the readme.txt

More info and Screenshots here: Portalmaps.wecreatestuff.com

Have fun.
Another great mod for Portal. Has less story than Prelude, but has more focus on puzzles than acrobatics. This is the mod that became an XBL arcade stand-alone, so based on that alone, it's pretty damn good. Plus its free for you unlike the consolites.


Gear map pack

The Gear Portal Map Pack is a series of Portal Maps, all revolving around Gravity as their main puzzle mechanic. After a promising that we would fix the last map pack, nearly 7 months later we've finally done just that! This time you can download the fixed map pack with challeneges included. Hopefully sometime later this Year, we'll get back to making more Portal maps using Gravity.
A fun couple of levels. Uses a gravity switch mechanic which I believe is part of Portal, but just unused. I had to noclip a few sections of this because some of the switches refused to work, but still worthwhile to check out.


Left 4 Dead

I Hate Mountains

No, it's not a joke, and no, we don't really hate mountains. "I Hate Mountains" is the name of a brand new Left 4 Dead campaign made by three french friends. This campaign is built the Valve way, we are not trying to revolutionize anything, we just want to provide more content to this awesome game. And if you're wondering why we're making a mod profile, ask INtense!
Made by the Portal: Prelude crew. Looks promising.

Team fortress 2

The Great Class Dash

The Great Class Dash is a single-player modification for Team Fortress 2 that transforms the game into a side-scrolling platformer. Players will have the chance to play four challenging levels. Additionally, the levels are filled with class-specific obstacles, meaning all nine classes will need to be used to beat the game.

A fun little side-scrolling TF2 mod. You pretty much just run along some levels in a TF2 setting, the vid can explain better than I can. Has a few minor glitches where players get stuck in the floor, typing "kill" in console can fix it.

Far Cry

The Delta Sector

The Delta Sector is a modification for FarCry which will meet the highest quality expectations and will use the full capacity of the Cryengine 1. There will be new weapons, new vehicles and new enimies in this mod. You are a member of a special forces team. It's your job to check what's happen in eastern europe, because many military forces accumulate in one area.
The Delta Sector is one of those few games that surpasses the visual fidelity of the game it is built on. Yes, that screenshot is in Cryengine, not Cryengine 2.

It's a pretty long mod, around 4 hours (I'm partway through, so that's a guess). Story: not anything really. Very difficult, AI has the same behaviour as far cry's so they can see you from 500 yards away through 10 trees and such. With all the extra graphical orgasm they added, it's really hard for you to see them.

S.T.A.L.K.E.R. Shadow of Chernobyl

Oblivion Lost


What is the purpose of this mod?

The purpose of this mod is to get closer to the old Oblivion Lost, and give the best performance possible, while implementing the best mod features:

Total free play, modified A-Life, reality enhancement, better AI, faction wars with cooperative game play.

It is recommended to play in HELL difficulty!
This mod works properly only with 1.0004 and 1.0005 patch!
Although the 1.0005 version is working with the 1.0006 patch as well, but that is just an MP Patch
Oblivion Lost was the original title for Staker:SOC. It modifies the Stalker campaign mode.

Oblivion lost adds a bunch of removed features from the game.
There are blowouts like in Clear Sky, so you have to find somewhere to wait it out first. This sometimes involves clearing out a enemy outpost very quickly so you get to shelter before the blowout hits. If you're lucky enough to have it happen in a safe zone like the bar, there might be a few stray mutants which your friends mop up. If you're in the military warehouses like I was once, you might have 3 controllers spawned. (yes that happened to me, and yes it was one of the greatest bits of gaming ever)
Revamped A-life:
A-life is much more random now, you can't just follow a path that used to have no resistance, as the NPC's are constantly moving and spawning, ans have much less restrictions than before.
There's also vehicles, artifact transformation, weapon repairing and a slew of other features I can't remember.


Stalker Complete 2009

This mod has been created with a thought of bringing the beautiful and immersive game of STALKER from the last generation era, when it was created to an up-to-date experience you'd expect from games you play in 2009. I did not try to include every single mod out there that changes the game beyond recognition, that was not the point. The following list is the carefully chosen essential collection of most advanced and aesthetically pleasant modifications, created by talented concept artists and programmers in the past 2 years. These are meant to technically and artistically enhance the game without compromising the original feel and atmosphere developers meant you to see. You'll notice every single detail has been retouched and has a polished feel to it.

This is ideal for first time players or people who have beaten the game when it first came out and now are coming back to replay it on new rig with higher resolution and better graphics.
Stalker Complete is a great mod to use if you're just getting into the crack cocaine that is Stalker, but are underwhelmed by the dated visuals. SC is basically a collection of mods, all put into one and tweaked to work together to produce visuals rivaling stalker clear sky. The gameplay changes are fairly minor, so you still get to experience stalker in all its' crazy post-soviet goodness, the way the developers meant it to be.


Unreal Tournament 3

FPS Terminator

A WIP mod for UT3. This initial release is just a taste of what direction the mod is going in. Hopefully it will not run into any legal issues, it looks great. UDK release, therefore UT3 is not required to play (mod is standalone).

Not really. They are different games in themselves for the most part built from the HL2/OB engine. They ARE NOT mods to tweak a games play style, appearance, etc.

Ill write up a review on Zombie Panic and Zombie Master within a few days. Have been playing both almost since release of them both.

1197 of them at this time (including under-production and dead mods)

The point of the thread is more to show the better mods, since it takes a long time to find something worth playing.

Added more mods:

City 7:
See Toronto like FPS_Doug does! Exterminate combine scum from teh best city ever.

Not much story, but good mapping and attention to detail. I was around 2 hours in when my computer broke down, so it's longer than 2 hours.

Riot Act
An excellent mod, one of my faves. Nova Prospekt environment, but combat is very well-done and levels are pretty.

Casualty Effect

HL2: wiimote mod

You spawn in a level, enemies are spawned, you get points for each kill.

The Island
You are on a random zombie-infested island. Your goal, get the hell off of it.

I have now gone through the entire moddb list, there are a few to add from fps banana still but it's pretty much complete in terms of the number of mods.

I can make a installation video or something for people who afraid of messing up their HL2 installation or something. Is there any need for this?
