Assimilant Menace!
This science-fiction roleplaying supplement expands the Assimilants, a cybernetic enemy race, for White Star and other d20-based OSR games. It introduces new Assimilant variants, cybernetic implants, Rigs, and three threatening starships, including two fighters and a cruiser. The supplement also presents two player character classes for individuals liberated from the Swarm: the enhanced Free Servitor and the symbiotic Free Node Brain. Guidance supports using Assimilants as stealthy infiltrators and other varied threats rather than only as cybernetic combatants.
