It's 2005 and Dr. Kimberly Stride has not had a good year. First, some freak scientist cooked up some homebrew DNA. But he blew it, and now it's a life-mutating supervirus! Dr. Stride tried to develop an antidote, but time ran out. Luckily, you have 15 missions to try to kill everything that's infected. Dr. Stride built a smart bomb, but just before launch, Orville (Dr. Stride's assistant)went ballistic and strapped her to it! Now you're steering this bomb over what's left of Earth, a slave to Orville's bizarre agenda!
