British publisher Modiphius Entertainment is expanding the world of its flagship tabletop role-playing game Achtung! Cthulhu by bringing the Lovecraftian mythos from the battlefields of World War II to the height of the Roman Empire. The publisher plans to launch Cohors Cthulhu in early 2023, providing rules for Roman legions and Germanic tribes to clash with each other — and with horrors from beyond the stars.
