Battleminer is an open-world block game set in a world where giant, mutant ants have taken over. Your mission is to rescue survivors that are hostage to the ants. A rescued survivor will reward you with items or teach you the ability to craft new items yourself.

While exploring the world you can mine for resources such as wood, copper, zinc and other materials to craft items to help you survive. As you progress you will encounter many different types of ants, each with their own challenges for the player.

There is also a Creative Mode where you can build your own structures and share screenshots of them via Miiverse.

The game features the first procedural voxel world with an infinite map size on Nintendo 3DS. Battleminer supports stereoscopic 3D and has a dynamic night and day cycle.

You wake up in an underwater cave.

Near the bottom of an enormous abyss, there's only one way out. Swim in a dark world under attack by frequent earthquakes and famine. This vast undersea kingdom is filled with both dangerous and hamless denizens. Its fearful inhabitants are led by a reluctant fish who has no answer to the impending disasters.

Take to the sea and help your new friends flee their home and find a new one. Their fate rests with you, Ikachan. You must help them find a way out before it's too late. Use whatever tools you can and try to escape. Swim, Ikachan, swim!
