It been 5 years since the Zombie Apocalypse has started because of a accident in Oscorp that spread a deadly virus to the whole world.

You willingly join Doctor Octopus for survival and let him use a experimental DNA drug to change you into a humanoid monster. Both you and him are immune to the virus, since his body is almost machine he doesn't need to eat and your humanoid monster body can just eat the rotten flesh of the zombies to survive. You both have been hiding in his underwater lab.
