Yeah it's nothing like the SNES and Sega games but it was never meant to be. There's no single player but they really could have made a rich campaign.
I wonder just how the development time was affected by the inclusion of cross-platform play. And whether or not the original idea for the game has been altered. Perhaps they originally planned a single player campaign but just couldn't finish it within the deadline.
It's not an auto-aim so much as "slow down when the reticule goes over someone."
It slows down the movement so you can be more precise but it does get annoying.
The no ladder climbing animation is similar to other online shooters, especially Counter Strike. I don't mind it because I don't use ladders a lot but it is somewhat distracting.
Anyway, if you couldn't tell by now, yes I have it. I've been playing it nonstop for 2 days so I got quite a few achievements already.
I only rented it because I didn't want to blow my money but I'm debating whether or not I should buy it. I'm just not sure it has the staying power I need for a $ 60 game. It's certainly fun though.
