Get bored during ZA? Make up a game with other survivors

Say like you already have a safe area during the zombie apocalypse, weapons as well, but you get bored after a certain amount of time, right? Well, gather up some friends (preferably of the human variety) and see who can get the most kills in a certain amount of time. Additionally, play human vs zombie with your friend that just got bitten... oh no what do you do now?! well its simple, just try to experiment on your half human, half zombie friend. Now any more questions?
