Fantastic game. I grabbed the 360 version, mostly because I enjoy playing multiplayer with friends on Live (I know too few who have PCs and frankly, Steam is annoying). This is, without a doubt, some of the "funnest" multiplayer coop you’ll have yet. The game is designed to require team work; and by require, I mean you better be coordinated because if you aren’t, it only takes second for things to go horribly, horribly wrong.
The game AI is all about surprises. Spawns don’t always come from the same place at the same time, and sometimes a spawn happens just for dramatic effect. The best example of this is when you’re trying to avoid the zombies (I guess you should know this is a zombie survival game wrapped around the premise of it being a zombie survival movie) and your team is about to enter the safe house. You’re the last to enter, and just as you get to the door, a zombie lashes a noose around your neck with its tongue and drags you away from the doorway. Now your teammates either let you die or come out and try to save you.
The drama.
You’ll be talking about the terrifying, exciting and often times stupidest side-splitting moments with your friends for days. Now that’s a fun multiplayer.
