Campaign is almost non-existent but it is fun while it lasts. Has some of the best mulitplayer modes I've played. There are negatives such and most are technical issues in the multiplayer which I'm sure will be patched. This is not a Resident Evil game as you don't have any of the atmosphere attached to the series but it's worth a playthru.
The game was fun but to short, the game play was the best part to me. But the story did not offer Much. I personally would not buy this game it was worth renting for shure. If the multiplayer was better I would say its a good game to own.
