The listed playing time for Aliens: Expansion is 90 minutes. This is the publisher’s estimate for a full game.

The catalogue lists Aliens: Expansion for ages 10 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone.
