Previously revealed as a PS3 exclusive in 2008, Tecmo has announced that Quantum Theory is exclusive no longer. The sci-fi third person shooter will now release on Xbox 360 and PS3 in Spring 2010.

At first glance, Quantum Theory looks like a Japanese made Gears of War with the partner A.I., cover mechanics and third person shooting all present. Perhaps the constantly shifting environment will provide some semblance of differentiation.

Many years have passed since the world war inflicted catastrophic damage on the human race, leaving only a few survivors. In their new community “Cocoon,” life has been threatened by a black material called Erosion, creating a post-apocalyptic environment. Surviving humans recruit a militia to conquer the Erosion and set out to take down the evil, “Living Tower”. Arriving at the scene is the stalwart warrior Syd, whose only intentions are to destroy the Tower. He meets the beautiful and mysterious Filena as they both ascend to the top in their search for answers. The erosion of the Tower intensifies as the players climb up through the moving landform.
