Good, but has issues.
It started off well, but when you get to the business end of things you start to really feel how little room there is to dodge zombies, which ended up being frustrating. The lack of large amounts of ammo for some weapons was annoying, especially the uzi. For a gun with such a fast rate of fire, you had to treat it like a rifle, squeezing off one shot at a time in order to conserve your ammo.
