Donkey Kong Bananza is a 2025 3D platformer developed by Nintendo EPD for the Nintendo Switch 2, released on July 17, 2025. It breaks from tradition with fully destructible environments, letting players smash through terrain to find hidden paths and collect golden Banandium Gems, while exploring sandbox-style underground worlds with teenager Pauline. Drawing inspiration from Super Mario Odyssey, the game features five animal-themed power-up transformations (like gorilla, ostrich, and elephant) that alter Donkey Kong's abilities. Development began after Odyssey under the input of Shigeru Miyamoto and Yoshiaki Koizumi, and it shifted from the original Switch to the Switch 2 due to technical constraints. Critics hailed it as the console's killer app, praising the visuals and gameplay (despite minor camera issues), and it sold 4.52 million copies, making it the second-best-selling Switch 2 game. As the first original Donkey Kong game since Donkey Kong Country: Tropical Freeze (2014) and the first 3D platformer in the series since Donkey Kong 64 (1999), it earned multiple Game of the Year nominations.
