I've been working on a zombie mod. Basically, everyone intially spawns on a human team except for 1 (or a couple, depending on settings) zombie(s). Everytime a zombie kills a human, they become a zombie. Once everyone becomes a zombie, the round ends. There are a few other little features that can be tweaked. It's currently running on [Wazu] Zombie Mod. Take a look and tell me what needs fixing

Edit:
A few other things that are worth mentioning: the mod is entirely server side, so it works with vanilla RE. Also, there are some new vars to play with that are explained in the README. My original intention was to only let zombies melee. Unfortunately, the AI code melees very poorly, so the server is currently running zombies with swords. This can be changed with the sv_zombieweapon variable.
