Core Mechanic

Roll d100 under your skill percentage to succeed. Matched doubles (11, 22, etc.) are critical successes or failures. Six stats (STR, CON, DEX, INT, POW, CHA) derived from percentile rolls. Bonds represent personal relationships and can be damaged as agents lose SAN. Sanity tracks Breaking Points — cross enough and you develop disorders.

Best For

Groups who want modern-day investigative horror where federal agents sacrifice everything — careers, relationships, sanity — to protect humanity from threats that should not exist.

Highlights

Bonds and sanity mechanics create personal drama, Need to Know quickstart is free and complete, strong atmospheric design, profession-based characters feel grounded, well-regarded published scenarios

Considerations

Dense investigative scenarios require significant GM prep, limited character advancement between operations, bond deterioration can feel mechanically punishing, SAN loss mechanics can remove player agency
