and i will make the zombies faster to spawn when there is that many of them, witch makes it harder to gather that much ammo.



yes, at the start of the game they should spawn faster, but later when zombies get killed they shouldn't raise again very fast, to leave some time to get ammo.

definitely the headshots need to make more damage, because it's very hard to defend yourself with pistol from more than four zombies. Also when you shoot to the zombie's knee they should stand up a little bit slower, allowing you to shoot other incoming zombies.

one more thing i noticed, when zombie is eating you, he's so close that you can't shoot him because all your bullets are starting to fly from behind him
