Outcast in Mars

On Earth, the androids try to reverse a zombie apocalypse, created by an extremely dangerous multimillionaire and computer genius: Colonel Saklas. Virtually the entire human race has been wiped out from the face of the earth, and the few remaining zombies are dying because there are no more brains to consume. However, this is only the beginning. Before the pandemic, millions of users were obsessed with a new online social media and social networking that allows the user to upload their "soul" into the machine. What they didn't know is that a gigantic server on Mars has been backing up these souls all along. What is Saklas' plan? Why does he want to destroy the human race? Why did he decide to preserve their souls on a server on Mars?
