About this game

MOUSE: P.I. For Hire is an action-packed first-person shooter that draws inspiration from the classic cartoons of the 1930s. Its black and white rubber hose visuals are drawn by hand, frame by frame, delivering a striking vintage aesthetic. Unravel layers of corruption with a thrilling noir-fueled detective story, lively environments to explore, an original big band jazz soundtrack, and a fully-loaded arsenal of cartoon weapons and devastating power-ups.

Meet Private Investigator Jack Pepper, a former war hero-turned-detective in a world where danger lurks even in the smallest mouse hole. Uncover the truth when a simple missing persons case quickly escalates into a complex web of intrigue, with corruption, kidnapping and murder all on the docket. Investigate the seedy underbelly of Mouseburg, battle heavily armed gangs and crooked cops, and discover clues to reveal the conspiracy buried underneath the surface.

From crackling machine guns to explosive firepower, each weapon in Pepper’s arsenal is designed to deploy non-stop cartoon chaos. Arm yourself with an array of classic, creatively twisted and experimental firearms, and consume powerful upgrades when you need that extra spinach-loaded punch! Lethal encounters and manic boss battles await in this boomer shooter-inspired, retro-vibed adventure - and the denizens of Mouseburg never go down without a fight.

Explore a diverse city playground, from dark streets to classic film studios, opulent opera buildings, poisonous swamps and underground sewers. With a myriad of cases to solve and collectibles to find, Mouseburg is truly a detective’s delight! Use every tool at your disposal to wall-run, grapple-hook and double-jump through this unrelenting cartoon world.
