It all started when a group of scientists wanted to find a cure for cancer. After years of studying they developed a substance. The substance was able to strengthen immune systems to a freakishly high rate but the substance wasn't stable. A month later after they studied the substance they thought it was stable and brought in patient to test on. The test was good so far after the substance was injected into the patient but, the patient eyes turned completely white, lost his ability to speak and all he craved was warm flesh and brain. The undead is upon us.
