Almost all players begin the game as humans, and must keep their ID cards with them at all times in case a zombie attacks them. If they are tagged, they must surrender their card, and become a zombie after one hour has elapsed. To defend themselves, humans are allowed Nerf Blasters, socks, or other approved toys. For protection, humans often band together and either stay hidden or attack the zombies directly. Certain areas are declared "safe" and humans can enter these areas without fear of attack. According to the Goucher rules, certain methods of eluding zombies are strictly forbidden; these include use of a car or leaving campus for extended periods. To draw zombies into the open and increase the speed of the game, humans can undertake "missions" with varying objectives.
