In Quantum Theory, players will experience Syd and Filena’s adventurous ascent through a treacherous tower in this dark fantasy, third-person/action shooter! Navigate through intense, shape-shifting battlefields, and perform powerful, two-character combo attacks with Filena in your quest to take down the “Living Tower.”
Many years have passed since the world war inflicted catastrophic damage on the human race, leaving only a few survivors. In their new community, life has been threatened by a black material called the Diablosis. The Diablosis infects everything it comes into contact with, tainting soldiers and the surrounding environment with its cancerous matter.

Surviving humans recruit a militia to conquer the Diablosis and set out to take down the evil, “Living Tower” that it is spewing forth from. Arriving at the scene is the stalwart warrior Syd, whose only intentions are to destroy the Tower. He meets the beautiful and mysterious Filena and they embark on their ultimate quest to take down the tower.
