Setup: Put Call of Duty or any other 1st person shooter in your game system and enter online multiplayer mode. Gameplay: Allow as many people as the game supports to join (Call of Duty games are either 1 or 2 players, Halo is 4). When you are playing, you drink when you die. If you are not playing, you pick a partner and drink when they kill someone. Switch after each game. We recommend playing game types where deaths are not important, so that everyone will play aggressively.
