Survive and satisfy your retained Objective. In this semi-cooperative game the shared Mission Task matters to some objectives, while other private goals can conflict with it. Escape alone does not establish victory: Infection, Eclosion and the final Objective check can still change the result.
Players take turns clockwise, normally resolving two Actions and then Oxygen loss and Fire damage, until everyone has Passed. The round then resolves Intruder burning and attacks, the Event phase and bag Development, followed by Cleanup. Cards pay for basic Actions or supply their own chosen printed effect; paying a card does not activate its effect.
This original four-player mission uses standard difficulty, Primebloods and the Primary Samples Mission Task. It follows nine rounds and all 72 turns through escape and the real endgame checks, with fictional players Mara, Nia, Tomas and Ivo. The route has fixed recorded outcomes and commentary; suggested alternatives do not generate another game.
