Earth Defense Force: World Brothers takes place in a 3D voxel world in which everything is made up of square pieces. In this world, the Earth is not round but square. And now, this voxel Earth has fallen into square pieces, breaking its blocky peace. But whether round or square, the Earth must be the Earth. So now, the player and the “EARTH DEFENSE FORCE” must rise to the occasion and save the day to restore a shattered Voxel Earth to one peace.
