In the early 21st century a virus has wiped out nearly the entire population. People that were infected by the virus were killed but woken moments later into a new life. A life that lives off of human flesh and tissue. A mercenary has been sent by his village/people to find a cure and look for signs of survival to restore humanity. This has been called the ‘mission’. Many people have tried and failed in the past. There has never been a person to return to their village after attempting to accomplish the mission.
