MOUSE: P.I. For Hire is a single-player first-person shooter set in a 1930s-inspired world of anthropomorphic mice. Players take on the role of Jack Pepper, a private investigator navigating the bustling streets and shadowy corners of Mouseburg while unraveling a web of crime and corruption. The game blends fast-paced gunplay with investigative elements, all rendered in a distinctive hand-drawn rubber hose animation style that evokes classic cartoons of the era.
Gameplay
Core gameplay revolves around a combination of exploration, clue gathering, and intense combat encounters. Jack moves through hand-crafted levels using wall-running, grappling hooks, and double jumps to navigate vertical spaces and reach hidden areas. Combat emphasizes constant movement, with players facing waves of enemies in arena-style shootouts that reward quick reflexes and positioning. An arsenal of cartoonish firearms, melee options, and experimental gadgets keeps encounters varied, while power-ups provide temporary boosts during tougher fights.
Investigative sequences break up the action. Players search environments for clues such as notes or photographs, then return to an office setting to piece together leads and advance the story. Side activities expand on this loop, including information gathering for allies and resource collection that ties into the larger narrative. The original soundtrack, composed by Patryk Scelina with contributions from Caravan Palace, underscores the jazz-fueled atmosphere throughout these sequences and battles.
Game Modes
The game centers on a single-player campaign structured around a main mystery that branches across multiple cases. Over twenty levels guide players through Mouseburg's districts, mixing linear story progression with opportunities for optional exploration. Side gigs serve as additional content, offering focused tasks that reward thorough investigation without altering the primary path.
No multiplayer components exist. All content stays within the single-player framework, allowing players to focus on the campaign's pacing and the integration of combat with detective work.
Visuals and Atmosphere
Black-and-white rubber hose animation defines the presentation, with every frame hand-drawn to capture fluid, exaggerated movements true to 1930s cartoons. Environments range from lively city streets to tense interiors, populated by mice, rats, and shrews that react dynamically to events. The big-band jazz score enhances the noir tone, shifting between energetic tracks during combat and more subdued pieces during quieter moments of deduction.
Is It Worth Playing?
Player reception has been strongly positive since the April 2026 release, with Steam reviews holding at Very Positive across thousands of entries. Many highlight the satisfying gunplay, memorable art direction, and engaging mystery as standout features. The campaign delivers a complete experience with replay value through collectibles and side content.
This title suits players who enjoy stylish single-player shooters that prioritize atmosphere and story alongside solid combat. Those seeking a fresh take on boomer-shooter mechanics wrapped in a unique visual package will find it rewarding, especially at its current price point. The blend of investigation and action creates a distinct loop that stands apart from pure run-and-gun titles.
