At least, with what little I've played. I've mostly wandered around to police stations and searched, and have found about four clips of ammo and a spare pistol. Unfortunately, I can't seem to aim well enough to shoot anything, so I'll probably need all the ammo I can get. I wasn't aware zombies were quite so difficult to keep aim on (I have something like a 30% hit chance, it looks like, and I started as a cop).
