Nemesis: Retaliation

Closed Doors block Movement (and Bursting) — you must Open or Destroy a Closed Door before moving through it; Intruders destroy Closed Doors when they attempt to move through them (p22).

Resolve the Exploration Sequence: place the Room and Corridors, then move your Character into the new Room, and then resolve the Entrance Effect (usually a Noise roll); Intruders placed or moved into a Room make a Surprise Attack immediately (pp24–27, p25).

When your Oxygen dial reaches 0 you gain a Suffocating token and keep the dial at 0; the token’s instructions give you effectively one more Turn to find Oxygen before you die (p17).

During Cleanup you draw until you have 5 Action cards in hand; there is no separate universal hand cap beyond this draw rule, and when you Pass you may discard any number of cards from your hand (pp15, p13).

Use the Infection Procedure (usually at End of the Game or when specified) to scan Contamination cards in hand for the word "INFECTED" and place a Larva if found; the Eclosion Procedure (typically End of Game) has you draw 4 cards and if any Contamination is in hand the Larva hatches and the Character dies (pp36, p38).
