I loved it, I love the mouse based control system, makes things very easy to learn. Reminds me a lot of basically a more mature version of Cooties (anyone who liked this control scheme I highly recommend that game) The slower motion when you jump makes for some awesome looking scenes, you can just put your fist in front of you and be a human battering ram or spin around as a meat grinder. DO NOT INCLUDE GUNS!!! I think it is fine without them, and really, I always hated in zombie games when you magically found military grade hardware and massive amounts of ammo in a civilian office building, it made no sense and cheapened things. Maybe some environment based weapons once you beat the game once would make things fun, like beating zombies with a fake office plant, computer keyboard, things like that. But don't start throwing in katanas or things that would make no sense. Sure, zombies are fake, but it doesn't mean you have to ditch any possible realism. A brilliant game, a great stress reliever, I love it.
