A rare four-page rules update for the independently produced boardgame The Conquest of Space. The update includes new scenarios, rules corrections, and variant rules.

The rules modifications include changes to scenario conditions, a rule to deal with "closed loops" in warp connections, and an optional rule for technology improvements.

Two new scenarios are included in the update:

Invasion of the Drecks is a solitaire scenario in which the player must fight off a fleet of alien spaceships.

The Cyborg Menace is a two-player scenario which adds a new type of spaceship, the Starstation. The designer credits the stories of Fred Saberhagen as the inspiration for this scenario.
