Task Force KGK consists of four members: Simon Ghost Riley, König, Keegan P. Russ, and Sebastian Krueger. Ghost is their leader. The world was thrust into a post-apocalyptic state after nuclear war broke out.

All remnants of previous society and government have collapsed and only very small, scattered settlements remain. Food and clean water are hard to come by and radiation is a big threat. Women are rare due to their survival rate being much lower than men.

The current Task Force KGK members are only a remnant, the previous members either splitting off after a disagreement or some other reason, or simply not surviving. Currently, they are in search of supplies, venturing out from their base camp. They come across a vast, desolate field with a single dilapidated farmhouse on it and decide to investigate.
