A new world is emerging

The Pangu Virus has been unleashed in San Francisco, turning thousands of innocent lives into mindless beasts that feel no pain and have no fear of death. With each passing hour, the Pangu Virus evolves, creating new and ever more horrific mutations with one goal in mind… Spread.

You are Captain Winter, a military officer fighting alongside the Center for Epidemic Research and Control(CERC). With a massive arsenal and the resources of the US Government behind it, you and CERC will stop at nothing to ensure the terror of the Pangu Virus does not escalate beyond containment, even if a whole city and millions of lives must be sacrificed.
