Half Life One, Half life One: Blueshift, half Life One: Opposing Force, Half Life One Deathmatch, Half Life Two, Half Life Two: Lost Coast, Half Life Two: Deathmath, Half Life Two: Episode One, Half Life Two: Episode Two. But I haven't completed Episode Two yet lol, haven't played in ages. I got to the bit with all the Walkers. I may play all of them in order from the start again lol, with all the Half Life threads popping up, it's inspiring me!
