Fortnite’s next big partnership with Teenage Mutant Ninja Turtles is here. Epic Games already lets players dress up as the Turtles, and now, creators can publish experiences built with TMNT assets and the Unreal Editor for Fortnite.

As a demonstration of what’s possible, Paramount teamed up with Spiral House (which has made other Fortnite experiences), to make a TMNT-themed beat-em-up / roguelike, TMNT Dimensions [Rougelike], that you can play inside Fortnite right now. (You can find it by searching for code 8651-4809-2485.) A lot of user-made Fortnite experiences look somewhat amateur, but this seems like a game you might actually want to play outside of Fortnite, especially if you’re already a fan of TMNT’s other arcade-y brawlers.
