Synopsis
Zombies are coming for the last remaining humans, and the humans must fight them off as best they can. All players but one join the Survivors team, which is the humans. The remaining player joins the Zombie team. The catch is that everytime a zombie is killed, he simply respawns and continues to play. If a human is killed, he respawns as a Zombie on the Zombie team. Of course, there is a little more to it than that....
