Our Take

Moon Colony Bloodbath is a darkly comedic deck-building game from Donald X. Vaccarino, the designer of Dominion. Players build moon colonies that are constantly losing population to the bad cards in the shared deck — engine-building and engine-losing in the same box. The last player with any colonists left wins.

Build a moon colony. Watch it implode. Outlast everyone

The rockets have launched. The colonists are loaded. The robots are programmed. Everything has been planned in exhaustive detail, and there is no chance of failure. There is, however, every chance of catastrophe, and the deck of Event cards waiting in the middle of the table is going to make sure of it.

Moon Colony Bloodbath is a deck-building game where the deck you're building is shared with the table, and the table has been making bad choices. Every card someone adds to the central deck stays there — including the ones that kill colonists. You'll engine-build with the goal of growing your population on the moon, but every shuffle through the Event deck triggers something, and the something is rarely good.

What makes it sharp is the engine-losing layer. Most deck-builders reward growth. Moon Colony Bloodbath rewards growing while the engine itself decays under you, and the dark humor of watching everyone's colony quietly collapse is the heart of the game. It's a Donald X. Vaccarino design, with the same precision you'd expect from the designer of Dominion, just pointed at a much darker target.

Deck-building groups, fans of darker-themed games, and players who like a bit of bite to their board games will all enjoy this. Plays 1 to 5, with the community calling 4 the sweet spot, and runs 45 to 90 minutes.

It's the kind of game where the table is laughing for all of the wrong reasons. If that's your humor, you'll love it. If it isn't, give this one a pass.

Frequently Asked Questions

How many players can play Moon Colony Bloodbath?
Plays 1 to 5 players. Community feedback most consistently lands on 4 as the sweet spot, with the shared deck filling up at a satisfying rate and the events hitting more frequently. Solo and two-player are both supported and play differently.
How long does a game of Moon Colony Bloodbath take?
About 45 to 90 minutes depending on player count and how aggressively the table adds disaster cards. Higher player counts trend toward the upper end of that range.
How does this compare to Dominion?
Same designer, same core deck-building mechanics, very different feel. Dominion is a clean engine-building game with no shared deck. Moon Colony Bloodbath uses a shared deck and an engine-losing layer that creates a darker, more interactive game with more direct fallout from your opponents' choices.
Is the dark humor a problem for younger players?
Probably. The theme is colonists dying in mostly-comic but consistently-grim ways. The game is rated 14+ for a reason. Pick a different deck-builder for family game night.
Is this beginner-friendly?
If you've played a deck-builder before, yes. If you haven't, Moon Colony Bloodbath is workable but a friendlier first deck-builder like Star Realms or even Dominion itself would be the gentler ramp.
Is there a solo mode?
Yes. Solo Moon Colony Bloodbath plays as a survival run against the Event deck — can your colony outlast the disasters before the deck runs out? Different feel from multiplayer but plenty of replay value.
