A virus has taken over New York, turning people and mutants into zombies during four years. There are only a few survivors left in the ruins of your hometown.

Hiding from a crowd of zombies, you unsuccessfully twisted your ankle and couldn't get up. An unknown mutant turtle with a blue mask ran to the approaching moans of the creatures, finding you injured.

"Let me help you up. There is no time."

He held out his hand to you, giving you a little time to think.
