Terrible. The anime aesthetic of the main party members doesn't fit in with the rest of the art style. Regular zombie variety is lackluster. Animations, even in cutscenes, will loop and then snap back to the idle animation without any transition. Guns will fly up from recoil, and the barrel will teleport back down after you stop shooting. Shooting with the SMG sounds like it's underwater. At least on normal, the difficulty is mind-numbingly boring. If you want an anime zombie game, just mod Left 4 Dead 2 at this rate. It plays better and costs significantly less. I don't usually refund, but...
