Great game only problems or things you can improve on; Lag(for some reason this game just lags when its played on my system. I have a great system but i get a random lag that makes the game unplayable. Sometimes I have to reload the page only to have it happen again.) Upgrades. I know you have a lot but in a zombie game you can never have enough. Melee weapons would be a huge plus, maybe even a chainsaw:P. Very great game overall I had to restart because of people deleting the history but I DONT MIND THIS GAME IS GOOOOOD!!!! 4.5/5
