Splatoon Raiders debuted on Switch 2 alongside version 1.1.0, a launch update that refines the game's audio mix and corrects technical issues discovered during development. The update is mandatory for online multiplayer access, though users remaining on the prior version will lose the ability to play locally with those who update.

Nintendo is complementing the launch with expanded media support, adding nine tracks from the game to its Nintendo Music service and releasing exclusive cosmetic icons in four staged waves. Though positioned as a single-player treasure-hunting adventure, the title includes both local and online cooperative features for players seeking shared experiences.
