The 1930s return as a first-person shooter in Mouse: P.I. For Hire

The new game pays tribute to the animation, music, and crime fiction of the era, without ignoring its politics.

The 1930s return as a first-person shooter in Mouse: P.I. For Hire

Less than an hour in Mouseberg makes it clear this is a city where people shoot first and ask questions never—and that Mouse: P.I. For Hire is a game with a lot on its plate. It’s a fast-paced first-person shooter where movement is key. It’s a platformer at times, and a little clunky about it. It’s a loving homage to the 1930s, from its animation to its jazz to its hardboiled crime fiction. Most importantly, it’s a game with such explicit parallels to the pre-World War II rise of the 20th century’s most notorious losers that you’d have to be ignorant or in denial to miss it. 

Developed by Polish studio Fumi Games, Mouse: P.I. For Hire immediately establishes its Depression-era fixation through “rubber hose” animation, a swing score, urban landscapes dotted with Vaudeville posters, and newspaper stories about strikes and mass immigration. It wastes no time moving from the cultural to the political, introducing its version of Nazis in an early mission. The degree to which the game’s Big Mouse Party mirrors infamous historical fascists—from its rhetoric, to its iconography, to its hostility to the law—is immediate and unmistakable, even before it digs into the oppression that the shrews (get it yet?) face compared to their mouse counterparts. Players will spend much time learning about all this as they solve several big cases that land at private eye Jack Pepper’s doorstep. Getting to know Mouseberg is to watch a city on the precipice of a familiar nightmare from our past, as subtext simply becomes text.

It’s far from a proper history lesson, if all the anthropomorphic mice didn’t tip you off. Mouse offers a unique story with often predictable but amusing twists that eventually diverges from its historical inspiration, but the takeaways will be similar. Still, Mouse approaches the subject matter in a commendable way. In 2026, it’s very easy to point at fascism and all but point a finger while screaming “Bad!” all day. Fumi Games does a bit more by showing how a deep hate for people based on identity isn’t the only way stupid and cruel systems are born. Moments throughout Pepper’s adventures show how opportunism and profit-seeking perpetuate those same systems too, making their apathetic devotees just as responsible for evil as those who fervently believe in race science. Mouse doesn’t use the ’30s solely as aesthetic reference points, but gives ample space to the political currents of the era—which is good to see, especially given how those ills have flared up so much this century.

Mouse: P.I. For Hire

As a game, Mouse is a familiar but entertaining ride. Each level is a pattern of climbs and descents where the slow pace of looking for clues, lockpicking safes with Pepper’s tail, and talking to micefolk is interrupted by enemies who come crashing in (often literally) with guns blazing inside makeshift arenas. The dashing and jumping required to survive these sections will ring a bell for anyone who’s dabbled in the ’90s-indebted “boomer shooter” space, and Jack Pepper has a sizable arsenal at his disposal to fend off the waves of mobsters, corrupt cops, and cultists that ambush him. While the enemy diversity is relatively slim and the loop quickly grows repetitive—especially the safe cracking—a few progressively unlocked mechanical twists and a modest playtime of about 12 hours prevents Mouse from turning into a bore. And, should you ever need a break from all the lead unloading, there’s a neat card-based baseball minigame where pitchers and batters face off based on assigned values and booster cards. 

Mouse knows how to keep things loose despite its more serious elements. Every mouse is always hopping a little in that Steamboat Willy kind of way. The weapons in Jack Pepper’s hands bend like rubber pencils while idly waiting for their next target. Dying doesn’t look as simple as sporting a new orifice; heads blow up like popped balloons with a shot to the head, bones collapse and stack after skin is melted off with acid, and piles of ash blink furiously when bodies burn alive. It’s more Itchy and Scratchy than Felix the Cat. Some enemies are literally pancaked when Pepper shoots down a hanging anvil or other heavy object. A special nod should be given to the boss fights, which feature not only some of the best character art in the game, but also some of the more creative battles. 

Despite its copious references, Mouse: P.I. For Hire feels best when doing its own thing. While it’s nice to have the nostalgia bone tickled when Jack Pepper throws back some spinach and gets to walloping like a certain sailor, the “rubber hose” style works best to sell Mouse‘s unique blend of zaniness. The animation style, while guilty of having racist origins like so many things rooted in America, encourages artists to follow their wackiest whims, and Mouse plays it a little conservative on that front. It’s hard to get tired of falling pianos and anvils, but there are as many ways to flatten a miscreant as there are artists with pencils and a dream. As a result, the moments spent on older fictional references like Popeye feel too safe, too predictable. They become “surprises” in the way that Star Fox being in the latest Mario movie is a “surprise”—you might not guess they’re coming, but when they do they’re not exactly unexpected. Once references are an established part of the package, any subsequent references won’t be as shocking or impactful. Mouse‘s references are never so egregious as to be deflating, especially given how brief and naturally woven-in most of them ultimately are in an affair so invested in the 1930s. Still, you might wonder what this game would look like if it spent even more time being original than playing the hits. 

Fortunately this doesn’t distract from the unique and smart gags Mouse does have. The game pulls off jokes that could only work when this particular story, this kind of rubber hose animation, and video games as a medium are combined by people who have a clear punchline in mind. Fumi regularly lands the set-up and the punchline, sometimes making the player part of the joke and treating you like any other cartoon character. 

It’s also a joy to talk to the characters throughout Mouseberg. While many will fall under familiar tropes, the main cast has a ton of personality boosted by accomplished voice acting work. Tammy Tumbler’s bratty young spirit and pub owner John Brown’s oh-you’ve-seen-some-shit attitude are highlights, but Jack Pepper is the clear standout performance. Even with the occasional cringe-worthy one-liner or cheese-laden monologue, Pepper’s a very human mouse with an imperfect but understandable worldview, one that’s fairly challenged by other characters even when the outcome of Pepper’s actions is good.

In many ways Pepper reflects Mouse: P.I. For Hire as a whole. Despite its reluctance to stray too far from its influences, it’s hard not to root for it all the way through. It tells a high-stakes story with a timely and sincere message, presents combat that borders on repetitive but is frequently a bombastic adrenaline rush, and doesn’t forget to lose its stiffness when the time to be deeply unserious arrives. It might be a cartoon game about a gumshoe mouse, but it’s also a worthy tribute to a scrappy but deeply troubled time whose cultural and political ramifications are still felt today.
