The gods of the four Elements - Water, Fire, Earth, and Wind - inhabit an asteroid belt, a remnant of their former world shattered into pieces. They are waging war on each other, each trying to reclaim the throne of Gaia. The player can choose to command any of the armies, taking it to victory through four campaign missions.
Additional game modes include versus and team fighter modes, which remove strategic elements, retaining only action battles. An editor is also available, allowing players to create and customize their own soldiers and units.
