Nemesis

Each round starts by drawing up to five cards. Players repeatedly take turns of two actions, one action and pass, or simply pass. Passing prevents further actions that round. After everyone passes, resolve time and self-destruct, Intruder attacks, fire damage, an event and bag development in order.

Basic actions normally cost one discarded Action card; Careful Movement costs two. A card ability requires discarding its own card plus the printed additional cost. Contamination cannot pay action costs. Room actions normally cost two cards and cannot be used in combat or in a malfunctioning room.

Entering an unexplored room reveals its tile and exploration token before resolving their effects. Normally roll for noise only when entering a room containing neither Characters nor Intruders. A numbered noise result targeting an occupied noise corridor causes an encounter; Danger instead moves eligible neighboring Intruders, or fills connected empty noise corridors if there are none.

An encounter clears connected noise markers and draws an Intruder token. Fewer cards in hand than its number, counting Contamination, causes a Surprise Attack. When the first Intruder miniature appears, everyone immediately keeps one Personal or Corporate Objective before that encounter is resolved; eggs are not Intruders.

Shooting spends ammunition and rolls a combat die. Melee first adds Contamination and a miss also causes one Serious Wound. A basic move out of combat lets every Intruder in the original room attack before a surviving Character moves. Careful Movement cannot be used to escape combat.

Every three Light Wounds become one Serious Wound; a Character with three Serious Wounds dies upon taking any further wound. Dressing disables a wound effect but retains it toward that limit. Ending your own turn in a burning room causes one Light Wound, rather than one wound per action.

The ship is destroyed when a ninth Fire or ninth Malfunction marker must be placed, not upon placing the eighth. A normal jump requires at least two working engines. Hibernating crew normally need Earth, with the Quarantine objective allowing its Mars exception. Launched pods count as reaching Earth but still face contamination and objective checks.

At the end, scan every surviving Character’s Contamination cards. At least one Infected card, or a Larva already on the Character board, triggers shuffling all their Action and Contamination cards and drawing four. Any Contamination drawn means death; otherwise they survive. A Larva skips scanning and directly triggers this draw, rather than automatic death.
