Humans V. Zombies

I didn't have enough time to completely finish, so I classify this as a joke game.

Follow these rules:

1. don't become a zombie. if you do, don't let the humans kill you

2.  use 1, 2, and 3 keys to switch weapons

3. enjoy, if you are able to. also don't play too long. just alt-f4, command-q, or whatever.
