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.
Hidden Intruder is a solitaire game – BUT it has 3 “scenarios” or different ways to play that allow for 2-3 players to play.
-Intelligent Intruder (One player plays the Intruder)
-Return to Prometheus (One player plays the Intruder, or 3 players each take a team of 3 troops)
-Science Officers (2 players, each control a separate team, with slightly different win conditions, allowing for one player or both players or neither player to win)
The game includes 54 counters 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.
You can get 3 different versions of the game –
-Basic – A 22″ by 17″ paper map in a ziploc bag with counters and rules.

-Deluxe – A 22″ by 17″ paper map in a box with fully stickered 5/8″ wood blocks for the counters and rules.
