There are still more than a few bugs in this "game preview" Even though I paid $60 for it a year after it's release it shuts down every ten minutes and even when I'm not near a zombie (a good 6-7 yards away) I'm still being hit by them. The game lags out and throws me into crowds of zombies on occasion as well all around this game needs to have the creators to go back and Redo a lot of the game!!
