Game Information

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.
