Mouse: P.I. For Hire Nintendo Switch 2 Update Details and Bug Fixes

Owners of the Nintendo Switch 2 can now download a significant update for Mouse: P.I. For Hire, developed by Fumi and published by PlaySide. This patch, released shortly after the game's April 16, 2026, launch, addresses a wide array of technical issues, including specific error code triggers, Joy-Con input quirks, and general stability concerns. While this initial update focuses primarily on squashing bugs and refining gameplay mechanics, the developers have confirmed that a more extensive performance and optimization update is scheduled for release in the coming weeks. For those tracking the latest developments at our Nintendo coverage, this patch represents the first major step in stabilizing the platform-specific experience.

Mouse: P.I. For Hire Switch 2 Patch Notes Summary

The latest update for Mouse: P.I. For Hire on the Nintendo Switch 2 is designed to improve the quality of life for players experiencing technical hurdles. According to the official announcement, the team has worked to resolve several progression-halting bugs that were previously reported by the community. Below is the breakdown of the specific fixes implemented in this version:

• Crash and Stability Fixes: Resolved a crash occurring when the game language was set to Traditional Chinese during startup or within settings.
• Progression Blockers: Fixed a logic error in the 'Far Wetlands' level where a door would fail to open, and resolved a blocker in 'Curdsville' that prevented level completion.
• Graphical and Collision Issues: Addressed a black screen issue in 'The Reel Deal' when lens distortion was disabled and corrected collision geometry in the 'Mouseburg Opera' mini-boss arena.
• Combat and Enemy AI: Improved enemy pathfinding in 'Quagmire' to prevent snagging on doors and adjusted movement patterns for the final boss in 'The Reel Deal'.
• Audio and UI: Removed corrupted sound effects from menu sliders and the weapon wheel, and added an option to exclude licensed music when the toggle is set to 'Off'.
• Quest Logic: Fixed missing quest items in 'Fart Harbor' and ensured the jailed Cop in 'Clergy Row' can be freed to collect the necessary clue.

Addressing Performance and Optimization

While the current patch serves as a necessary response to immediate stability issues, Fumi and PlaySide have acknowledged that the Nintendo Switch 2 hardware is capable of further refinement. We reported earlier that the team is preparing a secondary update specifically targeting performance. This upcoming release aims to optimize frame rates and engine efficiency, ensuring that the noir-inspired action of Mouse: P.I. For Hire runs smoothly across all handheld and docked configurations. Players who have encountered minor stuttering or inconsistent performance are encouraged to keep an eye on our patch notes hub for the official deployment date, which is expected within the next fortnight.

Beyond performance, the current update also introduces better background process management, which should help with overall system stability when closing the application. The developers have also updated the in-game Privacy Policy and added a feature allowing players to opt out of data and analytics tracking directly from the Settings Menu, expanding upon the initial onboarding options.

Refining the Player Experience

The adjustments made to the user interface and input handling are particularly relevant for those playing on the Nintendo Switch 2. Players who previously found themselves in a loop while attempting to rebind their Joy-Con controls will find this behavior resolved. Furthermore, the consistency of the D-Namite throwing animation has been improved, and a bug causing shotgun-wielding enemies to occasionally deal zero damage has been corrected, ensuring that combat encounters feel fair and responsive.

For those navigating the levels of Mouse: P.I. For Hire, the removal of geometry-based traps is a welcome change. Players should no longer find themselves stuck in the environment in 'Wallop Bay' or the six-door sequence in 'Tinsel Ave.' These fixes, combined with the improved quest handling, significantly reduce the likelihood of softlocks, providing a more seamless experience for players aiming to complete all side quests, including the 'Blueprint, please' objective which was previously inaccessible for some users.
