The Sentinel Project

For many years now, man and machine have collaborated to develop the ultimate biological weapon- a virus so powerful that it could erase life from half a continent in the span of only a few weeks. As time progressed into development, the Artificial Intelligence Unit (AIU) responsible for the safety containment protocols in the facility went rogue and deliberately started exterminating all human personnel. Survivors of the mutiny were eventually captured by the AIU and infected with the virus as experimental test subjects. Of those captured, you are the only survivor. For some unknown reason, you have become immune to the virus...  

Upon waking from unconsciousness, you realize that it is now your responsibility to decipher the deactivation code, while also avoiding the AIU, to prevent the complete desolation of humanity before time runs out. The fate of humanity is now in your hands.
