ok now i know alot of ppl are thinking wtf this game is short most of the campaigns are only 1 hour game 4 campains so at least about 4hrs 10 minutes but theres always online and the zombies are controlled differntly avery time they dont stay in the same place so that good and online is great dont get this game if you arent connected to internt just a waste of money always play online on this game theres also a versus mode which is amazingly addcitive and fun u can choose betweed the boomer smoker hunter and sometimes tank but its rare u have to tr to kill the survivors byu climbing walls to leap or grab them and sometimes throw a big chink of cement at them the campaign is fun too theres Dead Air Death Toll No Mercy and Death Harvest u can choose from an auto shotty shotty uzi m16 dbl pistols and sniper rifle u can get a molotov and pipe grenade now i know there are some down falls on this game like its toos hort not muhc weapons to choose from but im SURE there going to get patches or whatever for this game they'll have more guns and lvls maybe more boss infected to play as too so you should rent this first just to feel how the gameplay is some ppl are just stupid and rate them 3.0's because they either: havent actaully played it yet dontknow they will have patches for it or they just dont like zombie games or fps games or they just simply hate games in general and are trying to get ppl to not but this game well im here to tell you that u NEED this game
