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.GUMSHOE engine. Investigative abilities auto-succeed: if you have the skill and there's a clue, you find it. General abilities (combat, athletics) roll 1d6 + spent points vs. difficulty 4. Point pools refresh between sessions, creating resource-management tension. Four play modes (Burn, Dust, Mirror, Stakes) tune mechanics to your preferred espionage tone.

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 spy-thriller action fused with supernatural horror: burned agents unraveling a vampire conspiracy through investigation, chases, and tradecraft.
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 settingInvestigation never stalls: clues flow automatically, Conspyramid campaign structure is a well-designed GM tool, four tonal modes let you dial in the spy genre you want, highly modular vampire creation system, works stripped of vampires for pure espionage
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 editionNPC combat math can feel unbalanced against PCs, multiple point pools to track can bottleneck play, narrow genre focus limits reuse, requires significant GM prep for conspiracy networks
