MOUSE: P.I. For Hire looks like slapstick until schematics, manual saves, boss tools, and point-of-no-return choices start stacking up.

This is case prep: track the upgrade pieces, save before ugly stretches, feed one reliable weapon, and clean up before the story locks doors behind you.

Track The Upgrade Trail

Schematics are the route you do not want to redo later.

Track Schematics Early

Schematics feed weapon upgrades, and you cannot just buy back a bad route later. Mark them as you go before cleanup becomes detective paperwork.

Save Like A Paranoid Pi

Missions are not cleanly replayable from the menu. Use manual slots before big choices, collectible rooms, and boss stretches so one mistake does not own the file.

Save Before The Case Bites

Manual slots are cheap insurance.

Use James Gun For Pressure

The James Gun is a steady all-rounder when groups start crowding the room. Pull it out when suppression matters more than fancy single-shot heroics.

Bring Damage That Sticks

Bosses that move or teleport punish slow aim. Damage-over-time tools like the Devarnisher keep working while you reposition and stop panicking.

Bring Tools That Keep Working

Bosses punish slow aim and weak pressure.

Do Not Rush Jack Squat

Jack Squat is flagged as a point of no return. Finish side jobs, collectibles, and upgrades before you accept it, unless you enjoy locked doors.

Feed One Core Weapon

Spreading schematics across everything feels flexible until every gun hits like a stern memo. Upgrade one reliable weapon first, then diversify.

Clean Up Before The Lock

Point-of-no-return warnings deserve respect.

Clean Up Before Story Lock

Side jobs, newspapers, cards, comics, and upgrades can get locked out by progress. Treat cleanup like mission prep, not a retirement hobby.

Check The Route First

Some achievements are missable, and launch bugs have been reported. If you are trophy hunting, read the route before the case eats your weekend.

The Short Version

Track schematics, save like trouble is coming, upgrade one dependable weapon first, and finish side work before Jack Squat locks the case.
