The world has fallen to the dead, and creatures made by man. The CDC had been working on new creatures to release unto the world, for protection, they were to be used by the military. However, this experiment got out of hand and, well, all hell broke loose. These creatures, variants, brought the end of the world, turning people into the living dead, and now, only a few last survivors remain among the world. With these few remaining survivors, there's not much they can do, except survive. Sometimes, people don't like what must be done, but it must be done. Especially if they are to lose the people they care and love for, or even, themselves.
