I didnt particularly like it all that much.. its much too short of a game to pay 50 dollars for... the online play is 'okay' ... theres some really annoying lag at times and in a game where it is pretty crucial to be aware of the hordes of enemies youre thrown at you... you really NEED a lag-free game.. more so than other games. It's an ok game, probably not worth 50 bucks is my say. I did enjoy the online play, both the team and the versus modes.
I still like dead rising more in terms of zombie based games.. tho i do like that the zombies in this game were fast (well some of them). Also it could have used more varieties of enemies.
I'd say wait for it to go down in price then get it.
