The currently confirmed PC requirement for MOUSE: P.I. For Hire is light on paper: 11 GB of storage, Windows 10 64-bit minimum, and Windows 11 recommended.
This page keeps the public PC specs, native OS support, and current Steam Deck wording in one place.
Short answer
MOUSE: P.I. For Hire needs 11 GB of storage on Windows. The public minimum OS is Windows 10 64-bit; the public recommended OS is Windows 11.
Confirmed PC requirements
| Storage | 11 GB |
|---|---|
| Minimum OS | Windows 10 64-bit |
| Recommended OS | Windows 11 |
| Native PC platform | Windows |
Native OS support
There is no public native macOS or Linux version. For desktop PC, the official support target is Windows. Linux players are looking at Proton; Steam Deck players are also relying on that layer.
Steam Deck status
The developer FAQ says the game is "fully verified as Steam Deck Compatible for launch". The important nuance is that the Steam store page still does not show a public Valve compatibility badge, so this is a developer statement rather than a visible store certification.
What we still have not verified ourselves
We still have not verified frame-rate behavior, CPU load, shader stutter, or how aggressive the graphics options are in our own testing. Until that work is done, this page stays at the level of store-listed requirements and official wording.
