FOR IMMEDIATE RELEASE
London, England: 30th September 2025
Modiphius Entertainment, publisher of tabletop roleplaying games, wargames, and board games, has today released the core rulebooks for the tabletop roleplaying game, Cohors Cthulhu.
Initially funded on Kickstarter, Cohors Cthulhu is a tabletop roleplaying game of Lovecraftian horror set against a backdrop of epic heroism, intrigue, and strife during the height of the early Roman Empire.
Launching today, the Gamemaster’s Guide is available for £45 / $60 and the Player’s Guide for £35 / $47, along with the PDFs, collector’s editions, dice pack, and tokens. For those looking to dive straight into the game, the printed Quickstart is also available, featuring an abridged summary of the 2d20 System rules and six pre-generated PC characters ready to experience the included adventure.
Amid a war-torn and fractious world, in which Roman legionaries bent on conquest face off against barbarian warriors protecting their tribes, players take on the roles of diverse heroes from regions across the empire.
Enter a world of stalwart Roman legionaries, brave Germanic, Gaulic, and Celtic warriors,
shrewd schemers from Greece and Britannia, and valiant archers and mystics from lands
like Parthia, Aegyptus, and the island of Hibernia. Embody these heroes and forge unlikely bonds with former enemies to confront the Cult of Mormo, minions of Nyarlathotep and Yog-Sothoth, and other nefarious eldritch cabals.
This is the time of legends. This is the time of Cohors Cthulhu.
