Publisher PlaySide and developer Fumi Games showed up for IGN Fall Fan Fest 2025 to premiere a behind-the-scenes gameplay trailer for its black-and-white boomer shooter, Mouse: P.I. For Hire.
The minute-long video takes a peek behind the curtain to show fans how Fumi utilized hand-drawn visuals to create a stylized FPS that looks like a mix of Cuphead, Doom, and old-school Disney cartoons. It comes with an updated look at Mouse: P.I. For Hire’s many locations, characters, and weapons that call back to shows of the ‘20s and ‘30s ahead of its yet-to-be-announced 2025 release date for PC, Nintendo Switch, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X | S.
“It’s hand-crafted entertainment full of love, made for real people, by real people,” the Mouse: P.I. For Hire team says in the trailer.
Today’s IGN Fall Fan Fest 2025 sneak peek is also only a taste of what’s to come. Fans can expect to take a deep dive into the development of Mouse: P.I. For Hire when an in-depth making-of presentation premieres as part of the next ID@Xbox showcase Tuesday, October 28, at 10 a.m. PT / 1 p.m. ET. That elusive release date, meanwhile, will also finally be revealed as part of the Galaxies Gaming Showcase come October 23, which you can watch via IGN.
Fumi revealed its eye-catching shooter with a brief teaser trailer in 2023. Then, it was simply known as “Mouse,” with its full Mouse: P.I. For Hire title not arriving until its re-reveal in late 2024. Fumi and PlaySide have since added The Last of Us and Indiana Jones and the Great Circle star Troy Baker to their cast as rodent detective Jack Pepper, as players wait until next week for that PC and console release date.
We’ll learn more about Mouse: P.I. For Hire when its deep dive presentation arrives in a few weeks. In the meantime, be sure to check out our preview to see why we feel the upcoming boomer shooter fully embraces its hand-drawn aesthetic.
