Trollhunters: Tales of Arcadia is an animated series on Netflix that was created through a collaboration between Guillermo del Toro and Dreamworks. The series started in 2016 and wrapped with season 3 in 2018, but it has since spawned spin-off books and more. Now it appears a game is in the works.
Australian ratings boards have just added a listing for Trollhunters: Defenders of Arcadia, and as usual, the Aussie listing mentions the game as multiplatform. Doing a bit more digging, we can see that a Brazilian listing for the same title gets a bit more specific, and mentions Switch as one of the platforms getting the game.
It's likely we'll hear full details on this one soon, so we just have to hang tight. Thanks to Sephiroth_FF for the heads up!
