Learn how to play This Game is KILLER: Alien On Board, the hilariously deadly party game about surviving an alien threat aboard a cramped cargo vessel.

Quick Answer

To play This Game is KILLER: Alien On Board, each round you play two cards: a Position on the ship and an Action. The goal is to survive by containing the alien threat without getting killed.

Why the Two-Card System Matters

Unlike many social deduction games where you rely solely on bluffing or hidden roles, This Game is KILLER: Alien On Board forces you to commit to a location and an action each round. This adds a layer of strategy and consequence—you must anticipate what the alien might do and where it might strike. The two-card system also makes each player's choices visible (though the alien's identity remains hidden), creating tension and suspicion among the crew.

Step-by-Step Rules: How to Play This Game is KILLER: Alien On Board

  1. Setup and Deal: Shuffle the Position cards and Action cards separately. Each player receives a hand of Position cards and Action cards (exact number depends on player count). The alien player is secretly assigned—they keep their identity hidden. Tip: Make sure everyone knows the alien's win condition before starting: kill enough crew to take over the ship.
  2. Play Two Cards per Round: Each round, all players simultaneously choose one Position card and one Action card from their hand and play them face-down. Position cards indicate where you are on the ship; Action cards indicate what you do there. Common mistake: Forgetting that your Position and Action must make logical sense—some action cards have restrictions on where they can be played.
  3. Reveal and Resolve: All players reveal their two cards simultaneously. Resolve actions in order: the alien's action first, then any crew actions that might affect the alien. The alien can attack anyone in the same position as them, unless a crew member uses an action to defend or escape. Checkpoint: If the alien kills a crew member, that player is out for the round. Crew wins if they identify and eliminate the alien before it kills everyone.
  4. End of Round and Scoring: After resolving all actions, remove spent cards from play. Players draw back up to their hand size. The game continues until either the alien is killed (crew wins) or the alien kills the entire crew (alien wins). Tip: Pay attention to which cards other players have played—the alien might be forced into revealing themselves by playing a suspicious combination.
