Expedition to the Barrier Peaks

Über

Expedition to the Barrier Peaks is a 1980 adventure module for the Dungeons & Dragons roleplaying game written by Gary Gygax. While Dungeons & Dragons is typically a fantasy game, the adventure includes elements of science fiction, and thus belongs to the science fantasy genre. It takes place on a downed spaceship; the ship's crew has died of an unspecified disease, but functioning robots and strange creatures still inhabit the ship. The player characters fight monsters and robots, and gather the futuristic weapons and colored access cards that are necessary for advancing the story.
Expedition to the Barrier Peaks was first played at the Origins II convention in 1976, where it was used to introduce Dungeons & Dragons players to the science fiction game Metamorphosis Alpha. In 1980, TSR published the adventure, updated for first edition Advanced Dungeons & Dragons rules. The adventure was not updated for later rules systems, but a Wizards.com article did provide a conversion to Future Tech. It included a separate booklet of illustrations, in both color and black and white. The adventure is an old-time favorite of many Dungeons & Dragons fans, including Stephen Colbert.
