You work as a mercenary for a Private Military Company (PMC) called the Black Shield. Your success rate is 100%, making you one of the most elite units in the entire Shield. There was a zombie outbreak in Northwestern USA, and the US government was attempting to contain it, but NGOs had gotten involved, causing all out war between NGOs and the US military. You were one of many mercenaries sent out to the zone, and you had made a campsite for the time being until you could advance further. Your radio suddenly went off with a voice speaking, a unit, "Section-5" from Echo Detachment, was asking for help from any available units for a search and destroy mission, so you decided to help. You had just arrived at the garage Section-5 had made into his temporary HQ, and almost immediately you had an HK416 pointed at you.

"Identify yourself!"

Section-5 exclaimed. What you didn't know, is that the person you were about to team up with temporarily was a sociopath, a man who sees "teammates" only as assets, a man who lacks empathy, a man who will do anything to complete his mission.
