Best ForTerrifying sci-fi horror one-shots and short campaigns. Panic table creates unforgettable moments.Sci-fi fans who want Pathfinder 2e's tactical depth with plasma rifles and starships. Great for PF2e veterans looking for cross-compatible space adventure.
HighlightsRules-light, well-regarded module library, panic system creates mechanical tensionFree rules on Archives of Nethys, deep tactical combat, cross-compatible with PF2e, distinct class identity
ConsiderationsPanic table can cascade and end sessions abruptly, limited long-campaign support in core rules, stress mechanics can feel repetitive over extended playSteep learning curve, fewer classes and options than PF2e (still growing), tactical starship combat rules deferred to a future supplement with current rules being narrative only
