Monster Sanctuary is a Metroidvania-style monster-collecting RPG that combines exploration and platforming with strategic, turn-based combat led by a team of collectible monsters. Ability-gated map progression opens new areas as monsters gain skills.

Players explore an interconnected world, capture and train monsters, and battle using a deep skill-tree system that lets each creature specialize. Its fusion of Metroidvania exploration with monster-collecting strategy gives it a distinctive identity.
