Edit: All games can be played on single player, for extreme epicness
Survive: survive until a certain time limit or as long as you can hold out. Takes place in any map. 4-10 players
Outlast: Stay alive until you are the last person alive. Nonstop waves of zombies, no friendly fire. See who lives longest. Those who die will turn into a zombie? and attempt to kill others for (possible achivements?) Exp, cash and for fun.
5-20 players
Escape: Survive in a house for 5 minutes. Then, whenever you think it is safe, exit through main door ( barricaded at start, destroyed if zombies/humans deal too much damage to it, same with windows) Then take the fight into the streets and get onto a rooftop? to become evacuated. Will not take off if people are still alive, and not on the chopper. Friendly fire on/off 2-15 players
Deathmatch: See who kills the most amount of zombies in a certain time limit. Random starting point, friendly fire on. cant be turned off. 2-10 players
Edit: V.I.P: Players protect a civillian ( can possibly be a player?) From zombies, If Vip dies, everyone loses. Either get to a helecoptor ( faaaaaaar away) or escape the city/forest/rural area/ect. (Is also far away)
My rough draft as of now.
