The latest addition to Sonic Racing: CrossWorlds arrives today on PS5 and PS4, this time adding a quartet of new characters to the dimension-hopping kart racer. The Teenage Mutant Ninja Turtles join the fray in a premium DLC pack, and they're based on their appearance in the 2023 animated film, Mutant Mayhem. Here's a trailer showing them in action:Leonardo, Donatello, Michelangelo, and Rafael are all playable, and they bring with them the Pizzafire Van vehicle. Following the arrival of this add-on, there's still a fair amount of planned crossover DLC on the horizon. Avatar Legends is up next, launching in October, but in future we're seeing some pretty wild collabs with the likes of Godzilla and Evangelion.
