Once Upon a Katamari Hits Switch 2 Oct. 8 With Mouse Controls and DLC

For Katamari players, the practical change is control precision. Mouse input should make steering Le Prince’s growing ball of collected clutter feel more direct, particularly when threading through dense rooms or quickly changing direction to grab one more object before a timer ends.

Bandai Namco and RENGAME will release Once Upon a KATAMARI for Nintendo Switch 2 on October 8, 2026. The new version brings improved graphics and a smoother frame rate alongside mouse controls. That makes the Switch 2 edition the clear pick for newcomers choosing where to play, while preserving the series’ simple, strange central loop: roll up small objects, grow larger, then take on progressively bigger parts of each stage.

Existing Nintendo Switch owners are not being left with the original control setup. A free update will add mouse controls and performance improvements to the Switch release. The announced upgrade details do not promise every Switch 2 visual enhancement for the older hardware, so players mainly moving over for sharper presentation and smoother play should expect those benefits to remain tied to the newer version.

What Rolling LIVE Highlights adds

The paid Rolling LIVE Highlights DLC also lands October 8. It expands the game with 10 new quests, 12 songs drawn from Katamari Damacy Rolling LIVE, six new Cousins, and 18 accessories. Its headline gameplay addition is a magnetic tool that pulls nearby objects toward the Katamari, reducing the time spent lining up every small collectible and helping maintain momentum during a roll.

That package is most relevant to returning players who want more stages and customization rather than just a technical upgrade. Watch for final pricing and the exact Switch 2 upgrade path before launch.
