Core MechanicRoll a d6 dice pool (attribute + skill). Each 6 is a success. Stress adds extra dice — better odds, but stress dice that roll 1 trigger panic. Push rolls to reroll failures but gain stress. Cinematic mode for one-shots, Campaign mode for long-form play.Roll 1d6 (action die) + stat vs. two d10 challenge dice. Beat both = strong hit, beat one = weak hit, beat neither = miss. Momentum meter (-6 to +10) can be burned to replace your action score. Moves resolve fiction; progress tracks measure quests, expeditions, and combat. Oracle tables generate story prompts for solo and co-op play.

Best ForSci-fi horror campaigns and one-shots in the Alien universe, with a stress/panic system that mechanically drives tension. Supports both deadly cinematic one-shots and long-form campaign play.Solo or small-group sci-fi campaigns driven by sworn vows, with rich oracle tables, starship exploration, and collaborative worldbuilding — no GM required.
HighlightsStress and panic system mechanically reinforces horror tension, two distinct play modes (Cinematic and Campaign), Evolved Edition streamlines rules and improves layout, well-supported licensed settingStrong solo RPG design, 'Choose Your Truths' worldbuilding tailors the setting, large oracle chapter for emergent story, momentum system creates dramatic tension, three flexible play modes (solo/co-op/guided)
ConsiderationsTightly bound to the Alien IP with limited genre flexibility, stress mechanics can feel punishing at high levels, Evolved Edition changes are modest over 1st editionDense 400-page rulebook despite narrative focus, large move count to internalize, setting is human-centric by default, oracle-driven play can produce disjointed narratives without careful interpretation
