Genestealer (board game)

Genestealer is a 1990 expansion set published by Games Workshop for the science-fiction board game Space Hulk, adding new rules and miniatures built around the Genestealer Hybrids, human-alien offspring who fight for their alien progenitors using ranged weapons and psychic abilities rather than the melee-focused tactics of the base game's purestrain Genestealers. The expansion introduces psychic combat rules that let the alien side project mental powers across the cramped corridors of a derelict space hulk, adding a new tactical layer to the asymmetric confrontation between the outnumbered Space Marine boarding party and the swarming alien threat. As a supplement rather than a standalone product, it requires the original Space Hulk board game to play and was intended for owners looking to expand its scenarios and forces.
