Summary: A really enjoyable multiplayer experience on both Live and local co-op. Graphics are ho-hum and characters are not particularly enjoyable. I've been hit with some saved game bugs where if you max out all of your characters and then jump in a local multiplayer game your character stats will reset. Still this is a really fun game that I would recommend, especially if you are a zombie fan.
Summary: It starts out like it is going to be fun but this game is one of the most tedious, repetitive, annoying games I have ever played. Only 5 or 6 areas. No big difference between the 4 players you get to choose from. Just really really annoying and tedious. Especially past level 7. It isn't even fun! The only reason I even went through this hell hole of a game was to get the achievement at the end. The 7 days of hell was The regular game!!
