Assassin
A game in which there is much paranoia.
The names of all participants are randomly arranged in a circle and each player given a target- i.e., A would hunt B, who would hunt C, who would hunt D, who would hunt A. When the target has been eliminated, the killer then goes after their original victim's target. If B successfully kills C, they would then hunt D.
Games have been played by many people at many times. During Spring Term of 2009, multiple games involving over thirty people were played, and will continue being played in the fall. Particpants could be killed with a plastic spoon, a water gun, or a bomb- an alarm clock/phone alarm with the victim's name attached to it. They could also be killed by their own victim fighting back in self-defense. A lot of people foolishly died that way.
Faces and Facebook are both incredibly useful in this game, as they allow stalking of the target. Although played in fun, many people have been angered by this game due to the manner in which people use bombs. Since a bomb only has to be in the same room as the victim, they might not even realize one is in the room until they're dead. Also, since the assassin can't be in the same room as the bomb, they use third parties as a delivery method, sometimes angering a target who was naively trusting.
Sam Lewis won the first game by hiding in his dorm room until there was only one person left and then sending someone else after them with a bomb. The second game was won by Matt Rosso after a (failed) water gun shoot out and several days of cat and mouse.
