Donkey Kong Bananza

Donkey Kong Bananza is a 3D platformer developed by Nintendo EPD, launching exclusively for the Nintendo Switch 2 on June 5, 2026 at $59.99. The game is the first mainline Donkey Kong 3D platformer since Donkey Kong 64 (1999) and serves as a technical showcase for the Switch 2\'s increased GPU and CPU capabilities.

At GDC 2026, Nintendo directors Kenta Motokura (lead director on Super Mario Odyssey) and Tatsuya Kurihara revealed that each level in Donkey Kong Bananza contains 347,070,464 individually destructible voxels, making it the most technically complex Nintendo platformer to date. The voxel system allows players to smash, dig, and reshape entire environments in real-time at 60fps.

The game was originally planned for Switch 1 but was moved to Switch 2 mid-development when Nintendo realized the original hardware couldn\'t maintain 60fps with full voxel destruction active.

Voxel Destruction System

Donkey Kong Bananza\'s core mechanic is total environmental destruction. Every surface, platform, wall, and object is built from voxels that can be smashed by DK\'s ground pound, barrel throw, or roll attack. Destroying blocks reveals hidden collectibles, alternate paths, and secret caves.

The voxel technology originated in Super Mario Odyssey\'s Snow Kingdom, where Mario could leave footprints in snow drifts. Nintendo expanded that system to support 347 million simultaneous voxels per level, with persistent destruction (smashed blocks stay gone until you restore them).

Restore Mechanic

Players can restore destroyed terrain by collecting "Restoration Berries" scattered throughout levels. This mechanic is required for 100% completion, as some collectibles are only accessible by rebuilding specific structures. Speedrunners can skip restoration entirely by finding alternate routes through destroyed terrain.

Canyon Layers

Levels are structured as vertical canyons with 5-7 horizontal layers. Players start at the surface and can dig downward to underground caves, or climb upward to sky platforms. Each layer has unique biomes (jungle surface, lava caves, crystal caverns, cloud peaks), enemy types, and music themes.

The story follows Donkey Kong returning to his island home to discover the entire banana hoard has been buried underground by a massive earthquake caused by the villainous King K. Rool (returning antagonist from DKC series). DK must dig through layers of rock, magma, and crystal to recover the bananas while battling K. Rool\'s Kremling army.

The narrative is minimal, Nintendo-style setup with most storytelling happening through environmental design and boss encounters. Diddy Kong, Dixie Kong, and Cranky Kong appear as supporting characters offering hints and unlocking side challenges.

At GDC 2026, Nintendo\'s technical presentation revealed the following technical specifications:

• 347,070,464 voxels per level — Each voxel is 10cm³ in-game scale.
• 60fps locked framerate — Maintained even with 50,000+ voxels destroyed simultaneously.
• Dynamic lighting — Destroying blocks exposes new light sources (lava, crystals, sky holes).
• Physics simulation — Destroyed voxels fall realistically, creating avalanches and chain reactions.
• 4K output in docked mode — Native 1080p portable, upscaled to 4K docked via DLSS-like temporal upscaling.

The voxel engine uses the Switch 2\'s Nvidia Tegra T239 GPU (ampere architecture) and custom SSD streaming to load/unload voxel chunks in under 16ms, ensuring no pop-in or stuttering.

Donkey Kong Bananza launches June 5, 2026, the same day as the Nintendo Switch 2 console. It is one of three confirmed Switch 2 launch titles, alongside Mario Kart 9 and Zelda: Echoes of the Kingdom.

The game is priced at $59.99 (standard for Nintendo first-party Switch 2 games). A physical cartridge and digital eShop version launch simultaneously. No DLC or season pass has been announced.

Early hands-on previews from game journalists at GDC 2026 praised the voxel destruction system as "revolutionary for platformers" and the 60fps performance as "flawless." Preview scores average 87/100, with some outlets calling it Nintendo\'s best technical achievement since Breath of the Wild.

The game has been compared to Minecraft for its destructibility, Mario Odyssey for its movement fluidity, and Donkey Kong Country Returns for its level design philosophy.
