Mouse: P.I. For Hire - Length and Mission List

Released on April 16, 2026, Mouse: P.I. For Hire is an innovative FPS created by Fumi Games and published by PlaySide Studios. It draws inspiration from the "hand-made" black-and-white cartoons of the 1930s and casts the player as Jack Pepper, a private detective mouse. But how long does it take to complete?

Playtime and general structure

The main campaign can be finished in 10 to 20 hours depending on the player. Indeed, while levels last 30 minutes on average, some of them (the most complex ones, often the last ones and boss fights) can go over an hour of gameplay. While Mouse: P.I. For Hire doesn't currently have a New Game + mode or an endgame, the linear experience remains dense nonetheless. Expect 12 hours for a quick playthrough, 15-18 to explore everything, and closer to 20 to find all the secrets.

Full mission list

Mouse: P.I. For Hire features around twenty main levels built thematically into acts evoking 1930s film noir. Each mission alternates between frantic action sequences and investigation phases. Here is the list of missions and their narrative stakes:

• Mission 1: The First Client - Introduction to the gameplay. Infiltrate a shady bar to question a suspect. Learn the basics of shooting and dodging.
• Mission 2: Trails in the Alleys - Explore the hub for the first time. Collect your first weapon blueprint.
