StarQuest: Rescue at Rigel

In _Rescue at Rigel_ , you take the part of Sudden Smith, a human adventurer
teleported down by transporter beam inside a six-floor, sixty-room complex
inhabited by an alien race, the Tollah. Scattered throughout the base, which
has been hollowed out of an asteroid orbiting Rigel, ten humans are held
captive, one in each of ten different rooms. While you can adjust the
difficulty of the task, the object in all cases is the same: to search the
complex, find and release as many of the prisoners as possible (by activating
the transporter beam, which will teleport them back up to the ship), and get
out alive-in an hour or less.

If the Tollah base can be likened to an iceberg, you begin the game at the
tip: inside the top room, the only one that connects the complex with the
surface of the asteroid. (Since there is no air and no escape on the asteroid
itself, the door to the outside, being “off limits,” is not shown on the
display). From this vestibule there are only two usable exits. The larger
obviously leads to a gravshaft; the smaller looks like an ordinary doorway-but
there are no other rooms on the floor. Whichever way you choose to begin your
quest, there will be no turning back once you walk through the door.
