Intruder is a board game released in 1980 for 1–3 players, 30–60 minutes per game, and ages 10 and up. It was designed by B. Dennis Sustare and its main mechanics are Roll / Spin and Move, Area Movement, and Dice Rolling.
"IT'S LOOSE!!!" "Lab, this is command. WHAT'S loose?" "It broke out of the lab! It killed Jones!" "What is it? WHAT killed Jones?" "I don't know, but it's headed your way!" The Intruder is an alien being of unknown power. During the course of the game the Intruder will move through the space station as both the hunter and the hunted. One or more players must cope with a monster that moves rapidly and changes continuously as it undergoes metamorphosis into a more powerful being, and possibly divides into two or more clones. The game includes 54 multi-color die-cut playing pieces representing the crew and their weapons, lab animals (which confuse the search) and the Intruder. The playing map shows in detail the interior of deep space station 'Prometheus'. The map also contains special charts to record the development of the Intruder. Intruder is an exciting game of terror and suspense for one, two, or more players.

Intruder supports 1–3 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Intruder is 30–60 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Intruder for ages 10 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Intruder has a complexity rating of 1.9 out of 5 from BoardGameGeek players, which makes it a light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
