They enlist the help of their old ally, April O'Neil, and travel to the city's many parts to gather intel on Shredder's base of operations. Their journey brings them to the city's underbelly, where they find themselves in the middle of a turf war between different factions trying to take down the Foot Clan.

As they make their way closer to Shredder's lair, the turtles cross paths with familiar faces, including Casey Jones, Leatherhead, and the Mighty Mutanimals. Together, they launch an attack on the Foot Clan stronghold, facing off against familiar foes such as Bebop, Rocksteady, and the new mutant recruit Tremblor.

The stakes are high as the turtles fight to take back their home, but they soon realize that Shredder's plans run deeper than they had ever imagined. With the city in peril and their enemies closing in, the turtles must use all their training and skills to save New York from Shredder's control and restore justice to the city they love.
