Strategy First has announced that Submarine Titans, a real-time strategy game set in a futuristic underwater world, is shipping this week. Developed by Australia-based Ellipse Studios and distributed by Infogrames, the game is set after Clark Comet devastates the Earth in the 21st century and humankind turns to the seas for survival. Two human factions, the White Sharks and the Black Octopi, face off against each other and a recently discovered alien race that makes its way to the sea floor. Submarine Titans features 3D environments with five ocean depths that can be used for tactical advantage.
