It was a dark night when Shredder decided to use the time machine to destroy the Ninja Turtles and travel through time to finally destroy the Ninja Turtles. But suddenly after the time machine was activated, Hun and Shredder were exiled to a parallel world. Suddenly they realized that they were alone in this world, just them and the zombies that surrounded the whole world. Now they must fight to survive and win, and if they can, return to their own world.

Oroku Saki : We need to return to our own world as soon as possible.
