The Nintendo Direct September 2025 showcase was one of the longest in the company’s history, packed with surprises for Mario’s 40th anniversary. The event brought a mix of nostalgia and fresh content, headlined by a Donkey Kong Bananza DLC, Super Mario Galaxy remasters, and updates for Nintendo Switch 2.
DK Island & Emerald Rush DLC now available

Nintendo opened the show with a reveal that caught fans off guard. A new paid DLC for Donkey Kong Bananza, titled DK Island & Emerald Rush, is now live on the Nintendo eShop for $19.99. Switch 2 players can jump in immediately, but only after completing the base game’s storyline.
The expansion takes players back to DK Island, the lush jungle setting from Donkey Kong Country. Donkey Kong, Pauline, and familiar faces return as players tackle new challenges tied to Void Kong’s Emerald Rush Company.
Emerald Rush mode brings roguelike gameplay
Emerald Rush mode adds a roguelike twist to the game. Timed runs send players across DK Island and areas from the base game to collect emeralds, fossils, and Banandium Gems. These gems unlock unique power-ups for Donkey Kong, encouraging multiple runs to earn:
- New character outfits
- Collectible statues for DK Island
- Additional skins and rewards
The update blends classic platforming with replayable roguelike elements, giving fans more reason to keep returning after the credits roll.
Nintendo Direct September 2025 highlights for Mario fans
To celebrate the Super Mario Bros. 40th anniversary, Nintendo packed the Direct with first-party news. Among the biggest reveals:
- Super Mario Galaxy 1 and 2 remasters coming to Switch
- Super Mario Bros. Wonder is expanding the franchise
- Confirmation of a packed 2026 release lineup for Switch 2
Nintendo also offered a free demo of Donkey Kong Bananza, letting undecided players try the base game before buying the new DLC.
Switch 2 gains momentum heading into 2026
Released in July, Donkey Kong Bananza already earned universal praise for its inventive 3D platforming, destructible voxel-based environments, and deep move sets. The new DLC cements its status as an early Switch 2 masterpiece.
Meanwhile, the showcase made it clear that Nintendo is loading the Switch 2 library with heavy hitters by mid-2026. Between Galaxy remasters, Wonder, and anniversary content, fans now see a clear roadmap for the console’s next era.
The Nintendo Direct September 2025 wasn’t just a birthday celebration—it was a statement that Nintendo is ready to fuel both nostalgia and innovation for years to come.
