The world has gone to shit. The apocalypse has come. And it wasnt some nuclear explosion or anything like that. No. It was a disease, spread by fear. Humans finally did it. We killed all other life that had a beating heart. All animals are dead. On top of it, over the last 1000s of years we have cut down more trees and plants then we have put back. Because of this, some humans were the products of test experiments. They were used to see if humans could live without air. This ended horribly. They didnt mutate or kill. They just.. went completely mad. Years later human kind has somewhat.. adapted to less oxygen. However there are side effects to the loss of oxygen. For one, sometimes humans may.. see things. Other times they simply pass out. However because of this spreading fear of no food and less oxygen, humans became desperate. They began killing eachother as a source for food.
This is our apocalypse. A man eat man world. Canibals caused by fear. No one trusts eachother anymore.

And we are the last of this world of hatred. We've survived this long. Now some of us have banded together.however.. we still must hunt. If you are lucky you may find some animals that survived, but for the most part we hunt humans. Or, we farm vegetables.

Prepare yourself. You are stepping into a world of fear, hatred, chaos, and canibalism. If gore freaks you out, i advise you to step away.
