Earlier this month, Splatoon 3 received a hefty new update with Version 10.0.0, adding new weapons, the Urchin Underpass stage from the original Splatoon, gameplay adjustments, bug fixes, and Nintendo Switch 2 compatibility with enhanced resolution and improved framerates. Now, the addictive third-person ink-shooting game has been updated to Version 10.0.1, and while it’s not as exciting as the previous update, some major bugs have been patched out for a more stable experience.
Latest update: Ver. 10.0.1 (Released June 26, 2025)
Bug Fixes
Fixes to Game Operation
- Fixed an issue where the game tended to run slower than before when there were a lot of shots and characters on the stage so that the game will now operate at the same level as Ver. 9.3.0.
Fixes to Multiplayer
- Fixed an issue in Urchin Underpass where players could use unintended means to climb the outer perimeter of the stage.
- Fixed an issue in Urchin Underpass in Tower Control mode where players sometimes clipped into terrain.
- Fixed an issue in Urchin Underpass in Rainmaker mode where the goal distance did not change smoothly at certain places.
SplatNet 3
- Fixed an issue where “Next Freshness Up” did not display in Weapon Data.
Note: Compatible with Ver. 10.0.0 battle replays. Not compatible with Ver. 9.3.0 or earlier battle replays.

Mostly changes to Urchin Underpass. I thought that might be the case.
Yeah, that makes sense! Urchin Underpass has always been one of those maps that benefits from small tweaks rather than major overhauls. Curious to see how the changes affect gameplay — hopefully it keeps the flow balanced without losing that classic feel.
