Nemesis: Lockdown

Setup and objectives: prepare the base map, rooms, exploration tokens, power, Intruders, and Contingencies; give each player a character and two objectives. When the first Intruder miniature appears, secretly discard one objective and keep the other. Normally you must survive and fulfill that objective; other players’ results do not directly determine your victory.

Player Phase: draw to five cards, then pass the first-player token left except in round one. Take turns of two actions, continuing around the table until everyone passes. Taking only one action requires passing as the second; passing ends your actions for this phase and allows any number of hand cards to be discarded.

Costs and restrictions: basic actions, character cards, items, and rooms offer actions. Discard Action cards to pay the printed cost; using an Action card also discards that card itself. Contamination cards cannot pay costs. Room actions require your presence, no combat, and no malfunction; Computer actions have further power and other requirements.

Movement and Noise: reveal an unexplored room and resolve its Exploration token on entry. Normally roll Noise only when entering a room without another character or Intruder. Placing Noise into an already marked numbered corridor triggers an Encounter. Careful Movement chooses an eligible corridor instead, but does not cancel a Danger Exploration token.

Combat and darkness: sharing a room with an Intruder puts you in combat. Shooting spends ammunition and must use the Advantage die in a powered section. Escaping first resolves attacks from each Intruder in the starting room; move only if you survive. Darkness uses the higher Night Stalker Encounter value and may add event or attack effects.

Events and systems: after everyone passes, resolve CSS launches, time advancement and power thresholds, eligible Noise removal, Intruder attacks, Intruder fire damage, an Event, and bag development in order. Power declines at relevant thresholds. Research and other effects raise Knowledge; discovered weaknesses still require their Knowledge thresholds.

Survival routes: enter CSS pods only during an eligible time window; the launch token determines evacuation, and unsuccessful occupants return with a Serious Wound. Reaching the Bunker requires the Exit Room, an open Main Gate, no Intruder, and a Rover or Enviro-Suit. Isolation normally opens at time eight, or earlier through Alert; it does not protect against the facility exploding.

Ending and victory: time expiry, facility destruction, or no remaining active survivors can end play. A required thirteenth Fire or eleventh Malfunction marker also destroys the facility. Resolve Contingency, Contamination, then objectives; evacuation or Isolation does not bypass these checks. Surviving players who fulfill their objectives win, possibly together.
