A genetically-engineered virus, originally created as a cure for the common cold, turned into a lethal strain. It killed 75 percent of those injected and mutated 23 percent into nocturnal, blood-thirsty creatures attracted to sounds. They have incredible strength and speed and are now known as the “Virals.”
Only 2 percent of the human race appears to be immune.
In order to save the human race the uninfected must get to the nearest research bunker and be evacuated, by subway, to the next uninfected city known as “Safe Zones.”
As each safe zone gets overrun by the Virals, and the subways get derailed, the only way to stay alive and uninfected is to travel by foot to the next Safe Zone.
In order to do this, you must work your way through a maze of dark subway tunnels, old over-grown power stations, and small evacuated towns AS QUIETLY AS POSSIBLE, all the while avoiding the Virals that could be lurking around every corner.
Will you survive… ?
