The upcoming Dimension Shellshock DLC, announced back in June, which comes with the character Usagi Yojimbo, is now adding more pepperoni to the already amazing deep dish pizza that is Teenage Mutant Ninja Turtles: Shredder's Revenge. The amazing people at DotEmu and Tribute games have now announced Survival mode, which allows you to hop between dimensions, powering up after each match. It also allows you to "mutate" into other enemies, like Bebop, Rocksteady, and even Shredder himself. By the looks of the trailer, this mode can be played in multiplayer too. How much more could they possibly add? And how do we get 4 player online for Streets of Rage 4? (Yes, I'm that guy!)
