The developer posted the information on its official Japanese website ahead of the game s October 8, 2026 launch on Nintendo s next-generation handheld-console hybrid.
Performance and display
Bandai Namco states the Nintendo Switch 2 version of Once Upon a Katamari targets a maximum output of 4K when the console is docked and up to 1080p in handheld mode.
The company also indicates the game can run up to 60 frames per second, with 60 FPS described as the target performance level.
These figures represent a clear improvement over the original Nintendo Switch release, which was capped at 1080p docked, 720p portable, and a 30 FPS frame-rate ceiling.
Multiplayer, saves, and DLC
The publisher clarified platform compatibility and content policies for the Switch 2 release.
Online multiplayer will be supported between Nintendo Switch and Nintendo Switch 2 systems, allowing players on both consoles to connect.
Bandai Namco also confirmed there will be no cross-platform save support, meaning save data will not transfer between Switch and Switch 2 versions.
Additionally, the Switch 2 build does not include HDR support, and downloadable content purchased for the Nintendo Switch version will not carry over to the Switch 2 edition.
What's in the game
Once Upon a Katamari continues the series tradition of whimsical, object-collecting gameplay.
The release introduces new stages spanning eras such as the Jurassic and Ice Age, a new soundtrack, a magnet support tool to attract nearby objects, and a roster of 69 playable characters including the Prince and his cousins, each with customization options.
The title also features a four-player KatamariBall competitive mode with both online and offline CPU play.
