Unlike the original "EDF" series, which is drawn in a photo-realistic world, this game is boldly drawn in a voxel world! For people who just hate the look of huge real insects, or who are not so good at some brutal in-game expressions, this game can be your first EDF experience in which you can exhilaratingly defeat gigantic enemies.
A new battlefield appears in the "EDF" series. This time, the world becomes the square Earth. The name of this game is "EARTH DEFENSE FORCE: WORLD BROTHERS". This game takes place in the 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 is fallen apart 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.
Can no one live on a disjointed Earth? Yeah, you know the answer to that. The promise of the world of EDF is that the strongest people are always the general public. The broken Earth is alive in each area that has become parts, and all civilians are waiting for our help.
Cities around the world and those famous landmarks become stages, floating in outer space. Because the areas are disjointed, there exists a broken Earth boundary line (a huge cliff) at the end of each stage.
