Frequently Asked Questions
What platforms is MOUSE: P.I. For Hire available on?
The game is available on PC (Steam), PlayStation 5, Xbox Series X/S, and Nintendo Switch 2. It launched on April 16, 2026 across all four platforms simultaneously.
Are there missable achievements or trophies?
Yes — because missions cannot be replayed from the main menu, virtually all collectible-related achievements are missable. We strongly recommend saving frequently across multiple slots and following our Platinum Roadmap before starting.
What is the point of no return?
Accepting the mission "Jack Squat" permanently locks you out of the main hub and all side jobs. Do not accept it until you have completed every side job, collected all newspapers, cards, and comics, and upgraded your weapons.
What is the best weapon in the game?
The James Gun is generally rated the strongest all-round weapon due to its high fire rate and common ammo drops. However, we recommend upgrading the Devarnisher first — its acid damage ticks on bosses even when they teleport, making it invaluable for the late game. See our full Weapons Tier Guide for the complete ranking.
How many schematics do I need to upgrade everything?
You need 72 of the 89 available schematics to fully upgrade every weapon to Tier 3. That means you have 17 to spare. Unlike other collectibles, schematics cannot be purchased from the shop, so try not to skip too many.
Is there a New Game Plus mode?
No. MOUSE: P.I. For Hire does not include a New Game Plus or formal mission replay system. You can use the game's 50 manual save slots as a workaround to revisit individual sections.
Which difficulty should I play on?
There are three difficulty modes: Rookie, Detective (default), and Supersleuth. No trophies are difficulty-locked, so you can earn the Platinum on any setting. Supersleuth is recommended for experienced FPS players who want to engage with the weapon-switching and barrel mechanics intentionally.
Are some trophies currently bugged?
Yes. As of launch, several story-related trophies — including "Our Lesser Brothers," "Misfortunes of the Missing Magician," and "Smoked Cheese and Mirrors" — have been reported as not triggering correctly. The developers are actively investigating. Check our News & Patch Notes page for the latest status.
Does the game have DLC?
Yes. A Story DLC is available as part of a Steam bundle, alongside a Comic Book and Original Game Soundtrack. See our DLC Guide for a full breakdown and verdict on whether it's worth purchasing.
Is MOUSE: P.I. For Hire worth buying?
Reception has been very strong — the game holds an Overwhelmingly Positive rating on Steam with over 3,000 reviews at 95% positive, and earned favorable scores across major outlets. It's particularly recommended for fans of boomer shooters, noir aesthetics, and 1930s cartoon animation. For a more detailed take, see our review summary in the Beginner's Guide.
