There will be a 48-hour signup period for each game. Any number may participate.
Each round, you must PM the moderator with one of the following options: Shoot another player: Normally, this kills the player in question, but... Shoot yourself: If nobody shoots you, you die, but if anybody does shoot you, he or she dies instead of you. Shoot in the air: If nobody shoots you, you live, but if anybody shoots you, you die.
You have 48 hours to PM the moderator in each round. If you run out of time, you default to whichever of the last two options kills you. After the end of the round, the moderator will post who sent in what action and who is left after that round. A new round will be played with the remaining players. The last person standing wins and moderates the next game; if there is a tie, the mod of that game will start afresh with signups for a new game.
I know what you're thinking. "Did he fire six shots or only five?" Well, to tell you the truth, in all this excitement I kind of lost track myself. But being as this is a .44 Magnum, the most powerful handgun in the world, and would blow your head clean off, you've got to ask yourself one question: Do I feel lucky? Well, do ya, punk?
