Destiny 2's plot basically is the plot of the TMHT movie from 1990: The Footclan finds and destroys the Turtles hideout and kidnap master Splinter, forcing the Turtles to flee to an abandoned farm. While Splinter is in captivity talking sense into one of Shredders students, they meet a likable outlaw who helps them getting back into the city, exacting revenge on the Footclan and freeing master Splinter. They also find a new home in the sewers. Only difference is the Speaker dies while Splinter doesn't.
