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 three six-sided dice, two matched and one differently colored Drama Die, and add an ability score plus a focus bonus of +2 if applicable. The total must equal or beat a target number set by the GM or an opponent's result. Rolling doubles generates stunt points spent on combat, exploration, or social effects. The Drama Die's value sets the degree of success.

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.Groups who want a character-focused science fiction campaign of crew jobs, faction pressure, and danger across the Solar System. It suits tables that want structured action, investigation, and social encounters alongside ship travel.
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 settingBackgrounds, professions, talents, and focuses build characters with mechanical ties to their lives before the campaign begins. Action, exploration, and social encounters each use dedicated stunts, giving different kinds of scenes procedures beyond a single skill roll. The Churn turns accumulated complications into escalating story events, giving the Game Master a structured way to introduce setbacks.
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 editionCombat stunts are drawn from six separate category tables covering roughly sixty options, requiring both players and the GM to check charts mid-fight to keep pace. Ground and air vehicles receive no example statistics, leaving their combat rules almost entirely improvised. The forty-page setting guide summarizes the solar system's factions and history at a survey level, so groups wanting deeper political detail need outside reading of the novels.
