Cities on the moon! This will be humanity's crowning achievement. At last, no longer bound to the Earth, the moon, a steppingstone to the stars. The rockets are loaded with supplies and colonists; the robots are programmed and ready. Everything has been planned down to the tiniest detail, and there is no chance whatsoever of failure. To the moon!

Moon Colony Bloodbath is an engine-building, engine-losing tableau game, with a shared deck the players build that makes things happen, many of them bad things that kill people in your moon colony, but some positive, and some that let you build up.

More specifically, each turn one card is revealed from the shared deck, which starts with four work cards, two trouble cards, and two twists. For work, each player takes an action of their choice simultaneously: mining for money, farming for food, research for cards, build a new building, or restock boxes on buildings. Twists vary from one game to the next. Trouble adds a new event card to the deck: hunger, paperwork, glitches, accidents, leaks, power failure, whatever can go wrong will go wrong, then whenever the deck is shuffled, you can prepare for all those events once again.

Players can add cards to the shared deck, too, whether perks that are only for you or developments that affect all players.

The game lasts until one player's moon colony has no people remaining, or until the players reach the bottom of the event deck. The winner will be the player with the most survivors left at the end of the game. If tied, we will use these additional tiebreakers:

  1. Most number of buildings in play
  2. Most remaining money
  3. Most remaining food
  4. Most remaining boxes
  5. Most remaining building plans in hand
  6. Die roll

This is a class C event, so players do not need to know the rules before the event, we can teach and play within the two-hour time frame. 4-player games should take just a little over an hour, so there's plenty of time to teach as well. Games will be 4-player as much as possible, with some 3- or 5-player tables as needed.

For the Semifinal, we will take as many winners as we can, and fill to 16, 20, or 25 players, only accepting alternates to get to one of those numbers as needed depending on how many unique winners there are. Advancement will be based on the Heats: Most Wins-Points standard tie-breakers with GM specific tie-breakers listed below.

For 20 players in the Semifinal, we will play five tables of 4-players, advancing to a 5-player Final.

HEATS: MOST WINS - POINTS (HMW-P):

  1. Most Wins (e.g., total in all heats entered)
