Mouse: P.I. For Hire is a first-person shooter set in the noir world of Mouseburg, and its voice cast is just as sharp as its art style. If you have been wondering who brings the game’s lead detective to life, the answer is someone whose voice you have almost certainly heard before.
Troy Baker Voices Jack Pepper
Troy Baker voices Jack Pepper in Mouse: P.I. For Hire. Baker is one of the most recognised names in video game voice acting, best known for his roles as Joel Miller in The Last of Us, Booker DeWitt in BioShock Infinite, Sam Drake in Uncharted 4, and most recently as the lead in Indiana Jones and the Great Circle. His IMDB credits now exceed 400 roles, making him one of the most prolific actors working in the industry today.
Baker himself confirmed his enthusiasm for the project well before launch. He stated that he had been following the development of Mouse: P.I. For Hire since it was first teased, and that its art style, gameplay, and 1930s film noir aesthetic continued to win him over.
Who is Jack Pepper?
Jack Pepper is the star of Mouse: P.I. For Hire and the character you play as throughout the game. He is a war veteran turned private investigator operating in Mouseburg, a city with a seedy underbelly where corruption and danger run deep. The game begins with Jack investigating what appears to be a straightforward case, but things quickly spiral into a world of mystery and murder.
Despite the game’s cartoonish rubberhose art style, Jack is not a light-hearted character. Baker described him as someone who was offered every opportunity to be a hero and rejected it, until he no longer had a choice and finally found a good reason to step up.
One of the more creative choices Baker brought to the role was the idea that Jack’s classic film noir narration happens live rather than in flashback. So when Jack narrates something like “from the second she walked in, I knew I was in trouble,” the other characters in the scene can actually hear it. Baker pitched the idea to the team at Fumi Games, and they worked together to rework the dialogue to make it fit. It is a small detail that gives the character a distinct personality and comedic edge.
The Voice Cast of Mouse: P.I. For Hire
Troy Baker is the headline name, but the rest of the cast is equally worth knowing about.
| Character | Voice Actor | Known For |
| Jack Pepper | Troy Baker | The Last of Us, BioShock Infinite, Indiana Jones and the Great Circle |
| Wanda Fuller | Florian Clare | Silo, Industry, AFK Journey |
| Tammy Tumbler | Camryn Grimes | The Young and the Restless (1,318 episodes), NCIS, The Mentalist |
| John Brown | Fred Tatasciore | Invincible, Yakuza Kiwami 3, The Super Mario Galaxy Movie |
| Cornelius Stilton | Frank Todaro | Code Vein 2, Borderlands 4, Final Fantasy 7 Rebirth |
Wanda Fuller is the resident journalist of Mouseburg and a consistent presence throughout the game. Tammy Tumbler assists Jack with weapon upgrades. John Brown runs the Little and Big bar, and Cornelius Stilton is a politician who ends up helping Jack navigate the city’s corruption.
Why Troy Baker Was the Right Fit
Baker has spoken openly about what draws him to a project. For Mouse: P.I. For Hire, it was the tone. He explained that the team at Fumi Games had a laser-focused intent with every line of dialogue, every scene, every mechanic, and every piece of art, all aimed at nailing a very specific blend of gritty noir and comedy. He compared the tonal direction to the humour of Police Squad and The Naked Gun, which requires extremely precise timing to land correctly, particularly in a game where the player controls the pace.
Baker also noted that comedy in games is genuinely difficult to pull off well. Because the player has control over the speed of a scene, timing a joke requires real craft to avoid making it feel forced or gated. His experience across hundreds of roles gave him the range to handle that balance.
