It's been just over two years since Dotemu launched Teenage Mutant Ninja Turtles: Shredder's Revenge, the throwback beat-em-up tribute to Konami's TMNT arcade games. And now, the developers are launching the game's latest DLC, Radical Reptiles, with two familiar faces from the franchise's past: Mona Lisa and Mondo Gecko.

Mona Lisa was one of the characters created for the first TMNT animated series that premiered in 1987. She was originally human before exposure to a nuclear reactor turned her into a mutant salamander. In the animated continuity, Mondo Gecko was an ordinary gecko before he was mutated into a humanoid form. Although Mondo initially aligned with the evil Mr. X, he reformed and befriended the TMNT.

The game is also getting a new remixed original soundtrack from Tomoya Tomita, Keiji Yamagishi, Jake Kaufman, Sean Bialo, Anamanaguchi, and Button Masher. That updated soundtrack will be available as a free update for all players.
