Mouse: P.I. For Hire Review: Noir Never Looked So Animated

Introduction

The first time the Devarnisher hit a gangster cat square in the chest and I watched him dissolve into turpentine – his rubbery limbs melting like a forgotten sketch on a cartoonist's desk – I knew Mouse: P.I. For Hire was something special. Fumi Games' rubber-hose FPS takes the visual language of 1930s cartoons – think Steamboat Willie meets Cuphead – and wraps it around a noir detective story with surprisingly sharp teeth. You play as Jack Pepper, a mouse private investigator voiced by Troy Baker, navigating the crime-ridden streets of Mouseberg across 20-plus chapters of first-person shooting that channels classic Doom through a cartoon funhouse mirror. After completing the campaign in roughly 12 hours, I can confirm: the style isn't just for show. There's a good shooter underneath all that charm.

Gameplay & Mechanics

Mouse: P.I. For Hire understands that the best retro-style FPS games are about movement. You cannot camp behind cover – enemies swarm from multiple directions, and the game's multi-level environments demand constant repositioning. Double-jumping and wall-running keep you airborne and mobile, and the level design consistently encourages vertical play. It's closer to Ultrakill's kinetic energy than Doom Eternal's arena combat, though the difficulty is more forgiving on normal settings.

The weapons are where the rubber-hose aesthetic truly shines. The Micer is your basic sidearm, but the Devarnisher – which coats enemies in turpentine and literally dissolves them – is both mechanically satisfying and darkly hilarious. The James Gin serves as your shotgun equivalent with spread-shot devastation, and the Boomstick delivers the big boom you'd expect. Dynamite rounds out the arsenal for crowd control. Every weapon is designed with cartoon logic – they look impossible, they sound absurd, and they feel great to fire. The weapon upgrade station in Jack's office hub between missions lets you enhance each gun, though the upgrade tree is straightforward and lacks the depth of something like Doom Eternal's mod system.

Boss encounters are the campaign's highlights. Each boss has a distinct personality and mechanical identity – one requires you to dodge attacks while dealing damage in narrow windows, another has you chasing them through a collapsing environment, and a third spawns minions that you need to manage while targeting weak points. The variety keeps you guessing, and the cartoon aesthetic lets the designers go wild with character designs that would look absurd in a realistic game but feel perfectly natural here.

Between missions, you drive through Mouseberg in a top-down sequence to reach your office hub, which includes a dive bar for story exposition and the weapon upgrade station. These driving sections are charming the first few times but become repetitive over 20 chapters. A fast-travel option would have been welcome.

Graphics & Performance

Mouse: P.I. For Hire is one of the most visually distinctive games released this year, full stop. The rubber-hose animation style – hand-drawn character models with fluid, exaggerated movements set against painterly noir environments – is breathtaking in motion. Enemies squash and stretch as they move, projectiles bounce and wobble with cartoon physics, and every kill animation is a miniature piece of visual comedy. The customizable visual filters are a thoughtful touch – you can play in full black-and-white with film grain and flickering for maximum noir atmosphere, or dial it back for a more colorful, readable experience.

Performance is solid across platforms. On PC with a mid-range GPU, the game runs at a locked 60 FPS at 1440p without issue – the stylized art means it's not demanding on hardware. Console versions on PS5 and Xbox Series X target 60 FPS at 4K and deliver consistently. Load times are minimal, and I encountered no crashes or significant bugs during my playthrough. For an indie title, the technical polish is impressive.

Story & Narrative

The story is where Mouse: P.I. For Hire surprised me most. Jack Pepper is investigating corruption and murder in Mouseberg, and while the setup sounds like boilerplate noir, the writing commits to its dark themes in ways that contrast brilliantly with the cartoon visuals. Characters die. Betrayals carry weight. The central mystery involving Steve Bandel's robot-creation scheme weaves through themes of power, exploitation, and identity that give the narrative genuine substance.

Troy Baker's voice performance is perfectly calibrated – world-weary enough for noir credibility, wry enough for the humor. The supporting cast of cartoon animals playing hardboiled archetypes – the femme fatale cat, the corrupt police dog, the loyal but dim-witted sidekick – are genre cliches executed with enough personality to feel fresh. The tonal shifts between slapstick comedy and genuine menace are the game's strongest narrative trick, and they work precisely because the cartoon aesthetic lets you lower your guard before the story twists the knife.

Audio & Soundtrack

The jazz-fueled soundtrack is exceptional. Smooth saxophone lines during exploration, frantic brass during combat, and moody piano in the dive bar – it's a noir score that could have come from a 1940s film with a budget upgrade. Weapon sound effects are satisfyingly cartoonish – pops, bangs, and splats that complement the visual style without undermining the combat's weight. The spatial audio is competent, and Baker's vocal performance anchors every scene. It's one of those soundtracks you'll want to listen to outside the game.

Value & Replayability

The campaign runs approximately 10-12 hours on normal difficulty, which is appropriate for the genre but might feel thin at full price for players used to longer shooters. Higher difficulty settings add replay value, and hunting for hidden collectibles in each chapter extends exploration. The lack of a new game plus mode or meaningful post-campaign content is the biggest gap – once you've solved the mystery and upgraded your weapons, there's limited reason to return unless you want to replay favorite chapters at higher difficulty.

Compared to Cuphead, which offers similar visual spectacle but focuses purely on boss encounters, Mouse provides a more complete package with its full campaign, exploration, and narrative. Against full-priced FPS competitors, the shorter runtime is a consideration, but the quality per hour is high.

Final Verdict

Mouse: P.I. For Hire is proof that a strong aesthetic vision can elevate an entire genre. Fumi Games has crafted an FPS that looks like nothing else on the market, backed by satisfying gunplay, creative weapon design, and a noir story that knows exactly when to be funny and when to be dark. The 10-12 hour campaign has some pacing issues in the middle, and the between-mission hub world could use more depth, but the highs – the boss fights, the visual spectacle, Troy Baker's performance – more than compensate. An 8 out of 10 for one of 2026's most original shooters.

Buy if: You love Cuphead's visual style and wished it was a full FPS campaign, or you appreciate noir storytelling with a twisted sense of humor.

Skip if: You want a long-form shooter with deep progression systems, or the cartoon aesthetic doesn't appeal to you – it's the entire identity of the game.

Technical Performance

The PC version offers the highest ceiling for image quality, with support for DLSS and FSR scaling technologies. Load times are generally stable, and the overall experience is framed by mostly stable performance with occasional dips. Fumi has clearly invested in optimizing for available hardware, with occasional minor hiccups that rarely disrupt the experience.

Frame pacing holds up well during standard gameplay sequences. More intensive set-pieces – large-scale combat encounters, densely populated environments – occasionally stress the engine, but these moments are brief and do not undermine the broader experience. Players on PC, PS5, XBOX SERIES X can expect a polished, well-tested build at launch.

Bug density is low for a release of this scope. The most commonly reported issues at launch involve minor visual glitches and edge-case collision errors that Fumi is likely to address in post-launch patches. Overall, the technical state reflects a developer that has spent proper time in QA, and the performance score of 8/10 reflects an honest assessment of what players will encounter on day one.

Who Should Play Mouse

Mouse is a solid recommendation for enthusiasts for players who favour competitive reflexes and tight gunplay mechanics. If rubber-hose art style is jaw-dropping and unlike anything else in the fps genre appeals to you, this title will likely deliver exactly what you are looking for across PC, PS5, XBOX SERIES X.

Players new to the fps, retro genre will find Fumi Games's design approachable enough to serve as an entry point, while veterans will appreciate the depth hidden beneath the surface. The game rewards patience and exploration in equal measure, making it a strong fit for those willing to invest time in understanding its systems.

On the other hand, if 20-plus chapter campaign feels stretched thin in the middle sections is a dealbreaker for your play style, temper your expectations accordingly. Casual players looking for a low-commitment experience may find certain sections demanding, though the overall experience justifies the effort. For those on the fence, a trial run or watching early hours of gameplay footage is recommended before committing to the full purchase price.
