Catalyst Announce He Who Fights with Monsters TTRPG and Board Game

Catalyst Game Labs is bringing the bestselling litRPG series He Who Fights with Monsters to your game table - both as a tabletop roleplaying game and a board game.

He Who Fights with Monsters, by Travis Deverell (aka Shirtaloon), is a immensely popular series that was first published in 2021 and has the thirteenth book in the series coming out on 6th October 2026.

The series follows Jason Asano, an ordinary Australian middle-management retail worker, who is magically transported to an alternate video game-like fantasy world after an accidental ritual. Waking up naked, confused, and lost in this magical world, Jason spends his first day dodging cannibals, cultists, and low-level monsters while hunting for a pair of trousers. What is with litRPG series and their leading characters lack of trousers?

Grab some spirit coins, unlock some new essences, and head for the nearest gateway to astral space, because Catalyst Game Labs is partnering with Travis “Shirtaloon” Deverell to bring the bestselling He Who Fights with Monsters litROG series to your game table.

With twelve epic books already released and a thirteenth soon to come, He Who Fights with Monsters tells how Australian office-supply worker Jason Asano is transported to the world of Pallamustus and quickly learns the ways of becoming an adventurer and fighting the monsters that regularly appear. The books include compelling characters, fast-paced action, and of course a whole host of ways to fight monsters, making them great for tabletop excitement.

Catalyst Game Labs plans to publish a tabletop roleplaying game and a board game to help players get into the action. The roleplaying game will use catalyst’s Dice Core roleplaying system, modified in a way to allow players to build powers as they go from Iron rank to Bronze and beyond, becoming increasingly powerful as they fight. Three books are currently planned - a core rulebook, a monster guide (of course!), and a guide to the world and societies in it, including the all-important Adventure Society,

The board game is a competitive game where teams of adventurers fight monsters. Set in Greenstone and its surrounding areas, players must balance their resources to train their teams, acquire more gear, and beat the other players to the monsters springing up all over the realm.

You can sign up to receive updates on the games as they progress, and to access the alpha playtest for the roleplaying game rules, here.

For anyone attending Gen Con later this week, Travis Deverell will be on the Catalyst stand (booth 1611) signing authographs and giving our chocolate Spirit Coins.
