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 fifteen minutes. The goal of the zombies is to turn all the humans; the humans, meanwhile, must outlast all the zombies. 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.
Zombies All zombies wear headbands to distinguish themselves from humans. There is usually at least one original zombie, who starts out the game as a zombie, must start the spread of zombies, and in some rulesets is allowed to be free from wearing a headband for a fixed amount of time. Zombies must gather and input the identification number of all humans that they "turn" into the database to keep track of which humans have been converted. If a zombie is hit with a human's dart or sock, they are "Stunned" for fifteen minutes and cannot interact with the game until that time is up. If a zombie does not make at least one kill in 48 hours of play, then the zombie starves and leaves the game permanently. The different universities have different rules for the game. For example, depending on the number of players at the university, the game may start with more than one original zombie. Also, the amount of time varies as well as the time each zombie has to get at least one bite before dying. Some administrations bring players back, traditionally as a zombie, in order to make the final mission, objective, or overall finale more interesting. The rules for zombies are also known to change in storylines, traditionally after completed missions. This can include alternate stun times, transformation times, or death times. These possibilities make a zombie generally more directly affected by stories than humans.
Non-Players People who are not registered players are not allowed to interfere with gameplay. Under the original rules, this includes spying on the other team, or helping players stay in a safe area by bringing them food or doing something for a player which would otherwise require them to leave a safe-zone. If a non-player is shot with a Nerf dart or attacked by a player in any way, they should report the player(s) involved if the incident was intentional. Players who attack non-players will be banned under most rules. The original rules, and most University custom rules, stress the importance of safety in the game. The rules stress the safety of the players and non-players by not allowing realistic looking weaponry, weaponry which could hurt on impact, or dangerous behavior during gameplay.
Safe zones Since Humans vs. Zombies can last for days, rules establish "safe zones" where gameplay does not take place, and where players can stop participation in the game for a certain period. Safe zones are designated by the administrators in conjunction with University rules and/or other applicable rules. Safe zones include
dorm rooms,
bathrooms,
dining halls, Academic buildings, Health centers and other such places. Safe zones vary by the rules set at each separate University. Some include every building on the campus and all vehicles, others may exclude some, but not all buildings and vehicles. Players are also considered safe attending a mandatory academic or athletic event. They are not safe, however, going to or coming from these events. Some colleges also consider a "
wheel rule" where players are in a safe zone if they are on a
skateboard,
bicycle, or wearing
rollerblades. Generally, HvZ is played on-campus, so off-campus is considered a safe zone as well. Under the original rules, however, all Humans must sleep on-campus and being away for longer than 24 hours warrants automatic death or removal. Every area not designated a safe zone by administrators is considered a free-play area where players may tag or be tagged. Under the original rules, the game is played at all times and never stops until the game has reached the conclusion.
Missions Some universities incorporate missions into the game play to encourage more active participation. These missions usually come with a reward for the winning side. This reward could benefit the winners or it could penalize the losing side, and thus benefit the winning side. Missions can easily be modified in-game to account for how many players are humans and how many are zombies, or to make the mission easier for one side and/or harder for the opposing side. Missions can also be constructed to follow a storyline throughout the game. ==Controversy==
