MOUSE: P.I. For Hire Trophies
This platinum guide focuses on what can be verified right now: trophy totals, launch-week missable risks, the point-of-no-return around Jack Squat, and the hotfixes that changed clue and side-job reliability after release.
Trophy Shape
Launch-week trophy coverage agrees on the headline structure: 35 PlayStation trophies including 1 Platinum, 3 Gold, 18 Silver, and 13 Bronze. Steam shows 34 achievements, which is the same set minus the platinum.
Difficulty
Current roadmap coverage consistently reports no difficulty-specific trophies. If your goal is efficiency rather than style points, a low-stress cleanup run on Rookie-style settings is the safest way to protect the platinum.
Route Risk
The biggest threat is not combat difficulty. It is route discipline: side jobs, clues, combat misc trophies, and hub-only progress such as Baseball Cards become much easier to lose if you push the story carelessly toward Jack Squat.
Roadmap
This is a conservative route based on launch-week guide consensus plus official hotfix notes. It favors one careful playthrough with manual save protection over speculative shortcuts.
Step 1
Use the easiest setting you are comfortable with. Current trophy coverage indicates there are no difficulty-specific requirements, so there is no reason to make the collectible and misc cleanup harder than necessary.
Step 2
Before starting a main job, sweep the P.I. Office for new side jobs and keep a manual save. Launch-week roadmap writers repeatedly treat side jobs and in-mission collectibles as the main platinum killers.
Step 3
Knock out barrel kills, heavy-object kills, and other combat-specific trophies whenever the environment gives you a clean opportunity. They are easier to stack naturally than to force late.
Step 4
The case-related silver trophies sit close to clue logic and side-job completion. Because clue behavior was patched after launch, staying current on every available lead is safer than relying on endgame backfill.
Step 5
S'all in the Cards and Everybody Loves Rayguns both become more dangerous once the hub is about to close. Build card progress before pushing into the point-of-no-return phase rather than after.
Step 6
The cleanest roadmap consensus is to treat Jack Squat as the final commit point for hub tasks. Finish side jobs, clue-sensitive cleanup, card progress, and upgrade planning before starting it.
Missable Focus
The launch-window community consensus is that side jobs, clue-dependent case trophies, and hub-gated Baseball Cards progress are the biggest platinum risks. Current third-party walkthroughs consistently list 14 side jobs, and multiple roadmap sources warn that missing one can block Real Deal Gumshoe.
The safer mindset is to play MOUSE like a structured investigation. Between every major job, return to the P.I. Office, check for NPCs with new work, and avoid assuming the game will hand you a second chance later. If you are also tracking upgrade progress, pair this page with the Weapons guide and the future schematics pages rather than trying to improvise resource planning blind.
For collectible chains, treat newspapers, comic strips, and Baseball Cards as platinum-critical. Several launch guides describe the shop as a safety net for many misses, but they also warn that not everything is equally recoverable, especially when side-job rewards or late-game content are involved.
Patch Watch
Unlike some evergreen roadmap pages, this one is written after launch hotfixes had already started changing clue and side-job reliability. That matters for anyone reading older trophy advice.
Hotfix v1.0.4
Official notes say players could now correctly collect clue progress tied to the jailed Cop in Clergy Row and the Cheeselegger Foreman in The Old Subway, both feeding into Our Lesser Brothers and Secrets of the Shrew Shortage.
Hotfix v1.0.5
Official notes then fixed quest issues in Fart Harbor, including a missing NPC for Friends in Deep Places and a quest item for Slugs in the Shell. Those are side-job fixes, so they matter for completion planning even if they were not described as trophy fixes outright.
The practical takeaway is simple: if you are using any platinum roadmap written on or before April 17, 2026, compare it against the latest official hotfix notes first. Some launch-day warnings were about genuine route risk; others were about bugs that may already be partially addressed.
Version Note
This page uses official Steam achievement data, official Steam hotfix notes, and launch-week roadmap coverage published between April 16 and April 22, 2026. That makes it strong for a current platinum plan, but some exact edge cases remain patch-sensitive.
If your goal is a clean one-and-done platinum, pair this page with the Walkthrough, Collectibles, and Weapons sections rather than relying on memory between missions.
