When it receives its Dimension Shellshock DLC later this year, Teenage Mutant Ninja Turtles: Shredder’s Revenge will add a survival mode.
The Survival Mode will incorporate collectible crystals, which allow you to jump between differently themed dimensions. The trailer shows a Japan themed one, as well as the characters inside of the local TV station. As you progress through these different dimensions, you’ll level up and grow stronger, and can use crystals to unlock new lives, ninja power bars, Radical Mode and extra hit points.
The Dimension Shellshock DLC will be released later this year, and will also feature new character colours.
