Grimcoven is a cooperative miniature boss battler set in a dark Victorian universe where the hunt is all that matters.

Players take the role of hunters empowered by lament, bound together in a covenant to face modular boss battles. Each hunter features a unique development tree, allowing players to create powerful combinations of abilities such as teleportation, gaining extra dice, collecting lament, strengthening armor with electricity, or forging magical bullets for devastating attacks.

Every session offers a different experience by combining various arenas, bosses, elite enemies, and adventures. Rather than following a scripted campaign, players jump directly into an intense boss battle designed to deliver a complete 2–3 hour gameplay experience.

During combat, players strategically allocate dice to move, activate abilities, execute combos, and gather lament to grow stronger. However, accumulating too much lament comes at a price, as a hunter may ultimately transform into one of the very beasts they were sworn to destroy.
