Aliens & Artifacts
A science-fiction roleplaying supplement for the Spacemaster universe, adding alien sentient races, beasts, and advanced technology. It includes 14 fully described alien races, character creation rules for each, nearly 100 alien beasts across 11 ecosystems, and artifacts ranging from time-warping devices to deadly singularity seeds. World descriptions and adventure suggestions support exploration of these settings, while Rolemaster’s Claw Law provides rules for the creatures’ natural attacks.
