In a small rocky cove off the mainland, a city bobs on the top of the ocean, powered by an old and failing power source; the cores.

Once a bustling fishing hub and a center for deep-sea oil drilling, the machines have long since stopped, and all that remains of the now-sunken city is a single platform, barely staying above the waves. This is the last bastion of life in the rich waters here, the rest of the city's power has failed, and long since descended into the depths.

Far below the water surface, the generator for the city flickers and sputters. Those who rely on it for their power, and their lives, have activated the defense grid. The aliens have come. Defeat them, or lose the defense grid, and the lives of those who you've sworn to defend.

Waterworld is a large, fixed-path map, and is the first in a series of campaign-like maps. The map is (mostly) mirrored, and winds through the sunken portions of a once illustrious metropolis. Its power failing, and the city sinking, aliens have arrived to de-activate the defense grid, steal the cores, and put an end to the valuable lives here.
