The game plays like a simplified version of the Shredder boss level of the Super NES version of Teenage Mutant Ninja Turtles: Turtles in Time, only using the 2012 designs of the characters.  The game's title is a pun, referencing that it's an allusion to an older product (a "throwback"), and the method in which Shredder is to be damaged by throwing the Foot Soldiers back at him.
