Super Meat Boy 3D Adds MOUSE: P.I. For Hire's Jack Pepper in a Free Update
Meat Boy has a new ally who may soon regret taking the assignment. As of October 19, 2026, Jack Pepper, the detective from MOUSE: P.I. For Hire, is playable for free in Super Meat Boy 3D. Sluggerfly, Team Meat and Fumi Games have celebrated the crossover with a stylish noir trailer. Alongside the unlikely guest appearance, the update introduces DLSS, FSR and several technical improvements to the platformer.

A Private Detective Enters Meat Boy's Deadly World
Jack Pepper is usually associated with investigations in Mouseburg, dangerous firearms and a world inspired by 1930s animation.
Now he faces a rather different problem: surviving the levels of Super Meat Boy 3D.
On October 19, Headup and Sluggerfly announced a collaboration with MOUSE: P.I. For Hire, the first-person shooter developed by Fumi Games.
The crossover introduces another guest character. Jack Pepper officially joins the roster of playable characters in Super Meat Boy 3D.
The addition is free for owners of the platformer.
It is not a paid story expansion or a separate adventure.
An official trailer shows Pepper redesigned to match the exaggerated proportions of Meat Boy's world while retaining his recognizable detective appearance.
Black-and-White Noir Meets Colorful Platforming
The collaboration could have been limited to replacing Meat Boy's character model with a mouse wearing a trench coat.
Instead, the developers also explored the presentation of the two different games.
MOUSE: P.I. For Hire uses a monochrome style inspired by early sound cartoons and crime films.
Jack Pepper brings that identity into Super Meat Boy 3D.
The promotional artwork presents both characters together in a black-and-white environment.
French outlet ActuGaming also reports that selecting Pepper applies a film-noir visual treatment during gameplay.
This makes the crossover more distinctive than a simple appearance swap.
One game features colorful precision platforming and gruesome humor. The other is a detective shooter populated by cartoon rodents and gangsters.
The combination is unusual, but both projects share an enthusiasm for exaggerated animation and dark comedy.
Who Is Jack Pepper?
Jack Pepper is the protagonist of MOUSE: P.I. For Hire, developed by Fumi Games.
His original adventure follows his investigations in Mouseburg, where crime fiction meets classic animation.
The game is a first-person shooter with fast combat and a strongly recognizable monochrome aesthetic.
Some of that identity carries over to Super Meat Boy 3D, particularly Pepper's black-and-white appearance and detective accessories.
However, there has been no announcement that MOUSE's firearms or FPS mechanics are being fully integrated into the platformer.
The confirmed addition is Pepper as a playable guest character.
A Collaboration Built on Mutual Admiration
Fumi Games founder and CEO Mateusz Michalak believes the two games have more in common than their appearances suggest.
He describes the partnership as an opportunity to bring Mouseburg's distinctive atmosphere into the Super Meat Boy universe.
Sluggerfly co-founder and art director Dominik Plassmann emphasizes the process of adapting Pepper and his monochrome art style.
The challenge was not merely including the detective but making his visual identity work within another game's established presentation.
Both developers discussed the collaboration in statements distributed on October 19 and reproduced by several specialist publications.
Guest Characters Are Part of Meat Boy's Tradition
Crossovers are not entirely new to the Super Meat Boy series.
It has previously featured characters originating from other independent productions.
Super Meat Boy 3D continues that tradition with guests including The Kid from I Wanna Be The Guy and Pumpkin Jack.
Introducing a detective from a first-person shooter therefore fits an established tradition of celebrating independent games.
It works particularly well for a platformer built around short, repeatable attempts.
A guest character can change the visual identity of a run without requiring an entirely new campaign.
DLSS and FSR Join the Update
The crossover is not the patch's only addition.
The official changelog confirms support for NVIDIA DLSS and AMD FSR.
These image reconstruction technologies can help improve the balance between performance and visual quality on compatible configurations.
They are particularly relevant to players interested in additional PC graphics options.
However, the announcement does not identify the exact versions of either technology or provide measured performance improvements.
It would therefore be premature to promise specific frame-rate gains on individual systems.
Controller Vibration Is Now Supported
The update also introduces controller vibration.
In a platformer built around rapid movement, jumps and collisions, physical feedback can contribute to the experience.
Its precise implementation will need to be evaluated across different controllers.
The announcement does not promise specific DualSense adaptive-trigger functionality.
The developers also mention additional bug fixes.
However, the official announcement does not provide a detailed breakdown of every issue addressed.
A Meat For Hire Bundle Offers Both Games
Alongside the crossover, the developers have introduced a bundle called Meat For Hire.
It combines Super Meat Boy 3D and MOUSE: P.I. For Hire.
This commercial offer is separate from the free update.
Existing Super Meat Boy 3D owners do not need to purchase a new campaign to receive the announced character.
The developers advertise a bundle discount, although actual pricing depends on regional conditions and current promotions.
Interested players should check their storefront for the applicable price.
Super Meat Boy 3D Continues to Evolve
Released March 31, 2026, Super Meat Boy 3D represents a significant transformation of the original formula.
Moving into three dimensions required Sluggerfly and Team Meat to rethink movement and camera design.
In a PlayStation Blog development article, the studio describes spending considerable time refining movement readability and control.
That context helps explain why technical improvements continue to matter after release.
In a precision platformer where a small mistake can mean death, responsive controls and smooth performance are particularly important.
The guest character attracts attention, but the additional performance and usability improvements may also benefit regular players.
An Unusual Free Crossover Available Now
The Super Meat Boy 3D and MOUSE: P.I. For Hire collaboration has been available since October 19.
Super Meat Boy 3D is available on PC, PlayStation 5, Xbox Series X|S and Nintendo Switch 2.
Players can use a specially adapted version of Jack Pepper within the platformer's deadly environments.
The patch also introduces DLSS, FSR, controller vibration and several fixes.
This is not a complete gameplay overhaul or a major story expansion.
It is a free crossover whose appeal lies in bringing together two highly recognizable independent games.
Jack Pepper may be accustomed to dangerous investigations, but surviving Meat Boy's obstacle courses could make him miss the streets of Mouseburg.
