When alien threats descend upon the planet, you embark on a grand adventure. Born from a massive stone, you know nothing of this world. During your open-world exploration, every corner of the land hides mysteries and pleasant surprises. The creatures you meet along your journey can be either foes or allies. Gather clues from all manner of monsters to track down powerful bosses hidden deep beneath the earth. Loot materials from defeated creatures and craft them into loyal pets to fight by your side.

This game features a unique monster system unlike most traditional games. Neutral creatures spawn randomly across the map, offering crucial hints to help you explore and progress. They will also reward you with rare items, and may even join your party as companions by rare chance.

Every monster can be acquired in diverse ways. You can collect monster drops to craft corresponding creatures and upgrade their strength. The maximum number of companions you can carry is limited by your health. Most monsters can be encountered naturally in the world, while only a handful require special conditions to spawn.

Each category of weapons boasts unique practical functions. Swords clear overgrown weeds, axes cut down trees, and hammers are used for mining and quarrying. Trimming weeds, logging wood, and mining resources all have a chance to summon hidden monsters that do not appear through regular map spawning.

As your exploration unfolds, you will traverse distinctive biomes with unique scenery. You will also face regional puzzles exclusive to each land. Master elemental weapon abilities to solve environmental challenges — for example, using fire-based weapons to melt ice. When faced with obstacles you cannot overcome alone, turn to your loyal monster companions for aid.

Fantasy Workshop allows you to combine various map puzzle mechanics and terrain models to create your own creative maps; saved maps can be directly shared with friends to let them rack their brains and solve your puzzles, every player can become a game creator, and you are welcome to make puzzle maps even more amazing than the official game itself.
