About the game
Players build their own squad of monsters from scratch and, entirely alone, take on the wider world of the Crown Nation while standing up to fate itself. Thanks to the True Crossbreeding system, every monster ends up being completely unique to that player. The game is developed and published by Studio Aurum, alongside Red Art Games, and was released in 2026.
