"Expedition to the Barrier Peaks's" 32-page adventure guide is divided into six sections. These describe the crew's quarters, the lounge area, the gardens and menagerie, and the activity deck. Along the way, the characters find colored access cards and futuristic devices such as blaster rifles and suits of powered armor that they can use to aid their journey. The first two sections involve various monsters, vegepygmys—short humanoid plant creatures—who have commandeered the crew's quarters, and a repair robot that follows instructions before its batteries run out. There is also a medical robot trying in vain to find a cure for the virus that killed the ship's crew. In the lounge area, a "Dining Servo Robot" still works, although the "food" it serves is now moldy poison.
