MOUSE: P.I. For Hire casts players as Jack Pepper, a former war hero working as a private investigator in Mouseburg. A missing-persons case grows into a story of corruption, kidnapping and murder, sending Pepper into the city’s criminal underbelly to investigate clues and expose a conspiracy. Its detective premise gives the action a noir frame, while the hand-drawn, black-and-white rubber-hose animation draws on 1930s cartoons.
Combat follows the fast-moving rhythm of a boomer shooter: Pepper faces armed gangs, crooked cops and manic boss battles with a cartoon arsenal of firearms, equipment and consumable power-ups. Movement is part of the toolkit, too, with wall-running, a grapple hook and double-jumping, plus unlockable abilities for traversing levels. Mouseburg ranges from dark streets and film studios to opera buildings, swamps and sewers, with cases and collectibles to find along the way.
The listed format is single-player, built around a campaign rather than a shared multiplayer arena. Big-band jazz, expressive vintage animation and crime-solving exploration complete a design that mixes retro FPS action with a distinctly cartoon-noir identity. The documented description frames its play around that solo campaign and its city-spanning cases.
