From the depths of the sea to towering heights, you'll have to become the master of all of the Earth's atmospheres if you have any hope of saving the human race. Taking place in the 24th century, the game casts you as the last hope against four violent leaders who are attacking from the north. Most of the planet has been submerged underwater at this point, and you'll have to employ an array of futuristic weaponry to fend off this quartet of violent factions not to mention a host of environmental hazards. As many as four players can duke it out in this original strategy or adventure.
