Splatoon 3 Version 11.1.0 Update Brings Matchmaking and Multiplayer Balance Fixes

Nintendo rolled out Splatoon 3 version 11.1.0 on March 18, 2026, delivering balance adjustments to the game's matchmaking and multiplayer systems across both Nintendo Switch 2 and the original Nintendo Switch.

The update arrived against a backdrop of unusual activity from Nintendo this week. The company also pushed out a new Switch 2 firmware update and introduced a "Handheld Mode Boost" option, making the Splatoon 3 patch the third notable software change in a short stretch. Nintendo's Japanese support account had announced the update was coming at 10 AM JST, a post that drew significant community response, while Nintendo of America's official support page confirmed the March 18 local release date.

Beyond the patch itself, the development team signaled where the game is headed next. The team shared that the update following 11.1.0 will concentrate on "changes to the balance of battles," a phrase that points toward more substantive weapon or combat tuning down the line rather than the matchmaking-side fixes addressed now.

The full patch notes were not reproduced in available materials, so the specific matchmaking parameters or multiplayer variables adjusted in 11.1.0 remain undetailed. What is confirmed is that the changes carry across both hardware generations, meaning players on the older Switch and those who have moved to Switch 2 are on an even footing with this release.

Splatoon 3 has maintained an active update cadence since launch, and Nintendo's willingness to pre-announce the focus of a future patch suggests the live-service pipeline for the title remains deliberate and reasonably transparent. The next update's battle balance focus will be the one to watch for players who feel the competitive layer of the game needs adjustment beyond what matchmaking corrections can address.
