yeah, I have someone doing up different skins for the zombies, and I'll randomize them to get more variation.

But I like the "enemy projectiles" idea. What do you have in mind? rocks? knives?

You must understand something, that is not the only game mode. There are two others, one where you are in the open, and they come from all sides, and another where you must take the flag from one zombie infested base, to another.
