Theories on the zombie story say Samantha, Fluffy and Dr Maxis were all locked into the teleporter room by Ritchofen. Theories say Samantha became this super-nautral being which controls the hellhounds and zombies, and we know Fluffy became a hellhound. So, what abot Dr. Maxis? Well, there are 2 secret radios throught out Shangri-La I have discovered, and it sounds like Dr. Maxis. He must've been teleported to Shangri-La random area, knowing he was one of the patients to survive 115's power on the mind. He also created the teleporter, based on theories. With him is a partner, Dr. Peter maybe? Though, on the iPhone verson, in Shi-Ma-Numa there was a grave for Peter, but not on the xBox and PS3 version. Maybe Maxis and Peter survived? Also, I have theories on other items too, but I'll post em' later. So, give me your thoughts guys and post away!
