Aon, Rahk, Don and I got into some EYE last night. Game is buggy as fuck, but is surprisingly fun. It's an FPS RPG on Source, and has some of the best gunplay I've ever seen on the engine. It "supports " four players in coop, but from what we played, you couldn't tell. It looks like it's fairly trivial to up the max amount of players, though who knows if the game scales the enemies. I think we all found it a bit too easy, completing the first few levels in about 40 minutes (after 2 hours of trying to get the fucking thing to start).
Hopefully the rest of the idiots who bought it can play tonight before we get bored of it.
