Fear of the Unknown
1st EditionBest For
Groups who want a rules-light collaborative horror mystery that plays to completion in a single session, especially fans of horror films who want to investigate a mystery and face escalating dread without any GM prep. Works well for convention one-shots and players new to narrative RPGs.
Core Mechanic
Roll 2d6 and add tags: invoke up to three of your character's tags for +1 each, while the Oracle invokes up to two against you for -1 each. On 10+ you fully succeed, on 7-9 you succeed at a cost, and on 6 or less the Oracle chooses a consequence. The Encounter True Horror move instead adds your accumulated Horror to the roll, where a higher total is worse, so encounters grow more dangerous as dread builds.
The core loop is quick to learn: roll 2d6, invoke tags for bonuses, and read a short list of outcomes. The depth lives in three experience currencies (Horror, Humanity, Foreboding) that each build from a different trigger and unlock a different narrative move. Horror compounds the pressure: every supernatural encounter raises the danger of the next.

Highlights
Every successful Investigate roll hands the player a clue tied to the question they asked, so the mystery advances from what characters do at the table rather than from clues the Oracle hid in advance. The tags a player invokes on a roll become the fictional elements of the resulting scene, so each character's specific traits, not just the dice result, shape what happens in play. Each supernatural encounter permanently raises a character's Horror, which is added to future horror rolls, building escalating dread without a separate countdown.
Considerations
A single Face Peril roll resolves every dangerous situation, from a fistfight to a fall, with no initiative or enemy stats, so groups wanting tactical combat must build it themselves. The Oracle prepares no clues and improvises every answer to investigation questions live, which demands real on-the-spot creativity rather than prepared structure. The three-act structure and epilogue are built for self-contained one-shots, with no advancement loop for ongoing characters beyond gaining and losing tags.
