Humans vs. Zombies is a survival game of tag, where “human” players fight off increasingly large numbers of “zombies”; if a human is “turned” (i.e. tagged), then that player becomes a zombie in turn. At the game’s beginning, there are only one or two zombies; the zombies multiply by tagging humans, turning them into zombies after a period of one hour. Humans can defend themselves from zombies by using socks, marshmallows, Nerf Blasters or any other toys deemed safe and appropriate; if a zombie is hit by one of these methods of defense, they are stunned (not allowed to interact with the game in any way) for 15 seconds. The goal of the zombies is to turn all the humans; the humans, meanwhile, must outlast all the zombies.
