Katarzyna PetruFumi Games Studio has officially confirmed that their stylized FPS shooter, Mouse: P.I. For Hire, will debut on April 16, 2026. The game is coming to Xbox Series X|S and will feature full optimization for handheld devices from the day of release. The title stands out with its rarely seen in 3D games "rubberhose" visual style, reminiscent of black-and-white animations from the 1930s, set in a noir atmosphere.
Combat Mechanics and Retro Style 2.5D System
From a technological standpoint, the game implements the “2.5D” concept, placing two-dimensional, hand-drawn character sprites in a three-dimensional environment – which is a direct reference to the classics of the genre, such as DOOM and Wolfenstein 3D. The combat system is based on high mobility (dodges, double jumps) and a specific arsenal. The player can use, among other things, the “Boomstick” (shotgun) and the unique weapon “Devarnisher,” which shoots out turpentine dealing acid damage, leading to the cartoon world effect of dissolving enemy models down to their skeletons.
Exploration of Mouseburg and Detective Elements
The structure of the game includes an open-world map with a central hub in the form of the city of Mouseburg. The developers have implemented systems that go beyond standard FPSs: the B.A.N.G. workshop for weapon modification (e.g., alternate fire modes) and a evidence board in Jack Pepper's office, used for connecting clues and unlocking additional missions. A mechanical curiosity is the "tail pick" lock-picking system, which is a minigame based on the hero's tail movement, and numerous environmental puzzles requiring the use of explosives to unlock passages.
