Hey, soldier, listen up! There’s no repeat to this. The T12 virus has shattered containment at the Horizon research station. All the researchers have become walking carcass.
The virus is localized for now, but it could break out and cause a catastrophe anytime. You have to walk into that hell hole and decontaminate the station. Don’t try to save bullets – kill every last zombie.
The station’s corridors are full of enemies. It’s a good thing that you have a recoil less machine gun. Mop up and come home. Over and out.
