Volzerk: Monsters and Lands Unknown is an action-packed RPG game developed by COLOPL for Windows. The game takes place on the mysterious island of Fort Lemuria, where strange animals known as monsters roam free. As the protagonist, Fina, you join the Research Commission to explore the island and raise legendary monsters. However, the island guardian, Volzerk, has disappeared, leaving the monsters vulnerable to extinction.

The game features genuine action gameplay that combines characters and monsters in epic battles. You can mix and match monsters with different riders to master different skills, use different weapon types, and switch out characters at the right time to bring down powerful foes. The game also features a deep monster breeding system where you can crossbreed two monsters to give birth to a whole new monster that inherits its parents' abilities. Raise monsters to fit your own personal play style and take down the powerful enemies that stand in your way.
