Cthulhu Rift 2026

Strange rifts are opening throughout Arkham, allowing unspeakable horrors to enter our world.

In Cthulhu Rift, 1–4 investigators must work together to locate and seal these eldritch portals before the Old Ones break through. Every turn, players roll custom dice, record the results on their investigator sheets, and combine their abilities to close the rifts spreading across the city.

Cooperation is essential. Every decision matters, every action must be carefully coordinated, and every sealed portal brings humanity one step closer to survival… or one step closer to inevitable madness.

Arkham Files includes the complete Cthulhu Rift core game together with two additional cases that introduce new challenges, objectives and gameplay twists, plus a dedicated solo mode for investigators brave enough to face the Mythos alone.
