Maybe this is only a problem for me, but I have a fairly decent computer and even at the lowest quality setting my character was ground surfing and the aiming reticle was having an epileptic fit. Ignoring that, the gameplay seems pretty good, although It's kinda baffling that headshots don't take the zombies down. In every zombie game--hell, every shooter--I've ever played, the headshot is a test of skill for the player, and one that's rewarded with an instant kill. It especially makes sense in a zombie game because of the nature of that particular mythos. All in all it feels like a good game with more than a few bugs and some weird design choices.
