Nintendo has distributed a new maintenance update for Splatoon 3, advancing the game to version 11.3.0 on both Nintendo Switch systems. The patch delivers a fresh weapon alongside adjustments spanning multiple existing armaments and special abilities, as part of the company's ongoing approach to content expansion and competitive tuning.

The update introduces the Plastic-Bottle Shot Replica as its marquee addition, available to players who have completed the Splatoon Raiders campaign on the same profile. Accompanying this are modifications to weapon characteristics including damage falloff, ink consumption, shot accuracy, and area coverage, plus alterations to several special weapons' cooldown costs and mechanics. The publisher has indicated future updates will prioritise balance refinements for the game's multiplayer dimension.
