Submarine Titans plunges players deep into an immense and spellbinding underwater world, where three future civilizations are locked in battle for supremacy. In the year 2047, the Clark Comet strikes the earth with such astounding force that thousands of humans are forced to take refuge in subterranean vaults and makeshift installations beneath the ocean floor. Over the next century, humankind slowly adapts to their oceanic habitat and evolves into two rival civilizations: the White Sharks – who hunger for dominance over the underwater universe; and the technologically advanced and environmentally protective Black Octopi who will go to any extremes necessary to remain in balance with the Earth. As the Sharks and Octopi gather resources and build their forces to prepare for an inevitable clash, an alien race uncoils itself from within a resource-laden crater setting in motion an epic struggle that seems destined to destroy man’s final bid for survival.
