Description

Raise, train, and battle a charming roster of monsters in Mamon King, the strategic monster-raising simulation from LiTMUS, now also coming to Nintendo Switch 2 with a Game-Key Card physical edition while delivering over 170 skills, 38 unique Mamons, and deep turn-based tactical combat.

Mamon King is a monster-raising simulation RPG developed and published by LiTMUS. Players take on the role of a special tamer capable of forming bonds with mysterious creatures known as Mamons, raising them through training, tournaments, and expeditions with the ultimate goal of becoming the legendary Mamon King. Combining life simulation, monster breeding, and strategic one-on-one battles, the game offers an accessible yet surprisingly deep experience for both newcomers and veterans of the genre.

Rather than relying solely on combat, Mamon King encourages players to carefully nurture their Mamons, understand their unique strengths, manage their lifespans, and pass down their abilities through Inheritance Summoning. With 38 distinct Mamons, more than 170 unique skills, randomized growth systems, and board game-style expeditions, every playthrough offers new strategies and opportunities to build the ultimate monster companion. Originally released for Nintendo Switch and PC (Steam), the game later launched on PlayStation 5, with a Nintendo Switch 2 version arriving on October 8, 2026, including a physical Game-Key Card.
