 The game encourages cooperative gameplay, as the player will have to use each turtle's special abilities to navigate through their environment.The game's plot is based on the 2007 film "TMNT", but is told in the form of a flashback by the Turtles and Splinter.Unlike the console counterparts, the PSP and DS versions of the game are relatively similar to each other, though each in different ways makes use of the individual system's strengths.
