Best Games Like Mouse P.I. for Hire: Retro FPS Picks

If you loved the fast, mouse-driven combat of Mouse P.I. for Hire, the top pick for your next fix is ULTRAKILL. It delivers the same lightning-fast, movement-heavy gunplay and stylish arena combat, but with a modern, polished feel. The reason it wins is its perfect balance of speed, challenge, and pure mechanical satisfaction—it feels like a direct evolution of the retro FPS formula you already enjoy.

What to Look For

When you’re hunting for games like Mouse P.I., a few core criteria matter more than others. First, movement speed and fluidity—the game should let you zip around arenas, bunny-hop, and slide without friction. Second, gun variety and depth: you want a solid arsenal where each weapon has a distinct purpose and maybe a secondary fire that changes your strategy. Third, enemy design that forces you to move, not just stand and shoot—projectiles, melee rushers, and telegraphed attacks keep the combat engaging. Fourth, arena-based level design with verticality and open spaces, rather than narrow corridors. Finally, a satisfying difficulty curve—challenging but fair, with checkpoints or quick restarts so you can jump back into the action instantly.

ULTRAKILL

Strengths: ULTRAKILL is the gold standard for modern retro FPS combat. Its movement is incredibly fluid—you can slide, dash, and wall-jump, and the game encourages stylish combos by rewarding you with health for performing them. The weapons are inventive, from the revolver’s ricochet shots to the nailgun’s magnetized projectiles, and each has a niche. The level design is arena-focused with plenty of verticality, and the enemy AI is aggressive, keeping you on your toes. The soundtrack is a banger, too.

Trade-offs: It’s fast and can be overwhelming for newcomers; the difficulty spikes are real. The story is minimal, and the aesthetic is more industrial/hellish than the noir cartoon of Mouse P.I.

Who it suits: Anyone who wants the closest thing to a spiritual successor to Mouse P.I.’s combat, with a high skill ceiling and endless replayability.

DUSK

Strengths: DUSK is a love letter to 90s shooters like Quake and Doom. It has a gritty, horror-infused atmosphere, but the combat is pure, fast-paced arena shooting. The weapon roster is solid—dual-wielded shotguns, a crossbow with explosive bolts, and a chainsword for melee. Levels are a mix of open arenas and tight corridors, but the movement is snappy with a great bunny-hop mechanic. The enemy variety is excellent, from cultists with shotguns to invisible stalkers.

Trade-offs: The tone is much darker and more violent than Mouse P.I.’s cartoonish vibe. The story is cryptic and optional. It’s a bit more grounded in its movement, lacking some of the advanced tech like dashing or wall-jumping.

Who it suits: Fans who want a pure, no-frills retro shooter with a horror twist and a focus on classic strafe-and-shoot gameplay.

Prodeus

Strengths: Prodeus combines modern rendering with retro gameplay. It looks gorgeous with its particle effects and gore, but the core is classic: fast movement, a big arsenal of punchy weapons, and intense arena fights. It features a level editor and community-made campaigns, giving it massive replay value. The enemy design is varied, and the difficulty modes let you tailor the challenge. The shotgun feels amazing, and the game supports both keyboard/mouse and controller well.

Trade-offs: The visual style is more “gritty tech� than cartoonish, and the game can get chaotic with lots of on-screen enemies. Some players find the later levels drag a bit. It’s less about stylish movement and more about raw firepower.

Who it suits: Players who want a modern-looking retro shooter with a strong community and modding scene, and who enjoy a more straightforward, run-and-gun experience.

Ion Fury

Strengths: Built on a modified Build engine (the same as Duke Nukem 3D), Ion Fury is a true retro experience with a cyberpunk setting. The protagonist, Shelly, is a badass with a unique weapon: a “Loverboy� pistol that can charge up shots, plus a variety of explosives and a shotgun. The level design is intricate, with secrets everywhere, and the movement is surprisingly fluid for the old engine—you can slide and crouch-slide to dodge. The enemy AI is decent, and the game has a great sense of humor.

Trade-offs: The engine shows its age—no true 3D models, and some modern QoL features are missing. The pacing is a bit slower than Mouse P.I., with more exploration and puzzle-like level progression. The combat is less about arena waves and more about navigating spaces.

Who it suits: Fans who want a genuine retro feel with a strong female lead and a focus on exploration and secrets, not just pure combat.

Amid Evil

Strengths: Amid Evil is a fantasy-themed retro shooter that plays like Hexen but with modern polish. It features a variety of magical weapons—a sword that shoots energy waves, a staff that fires homing projectiles, and a trident that creates lightning storms. The movement is fast, and the level design is expansive, with a focus on verticality and open arenas. The visual style is beautiful, with vibrant colors and a dark fantasy aesthetic. It also has a great soundtrack and a satisfying secret-hunting element.

Trade-offs: The fantasy theme might not appeal to everyone if you prefer sci-fi or noir. The game can be quite challenging, and some levels are labyrinthine, which might frustrate players who prefer linear action. The weapon switching feels a bit clunky compared to other modern retro shooters.

Who it suits: Players who want a magical twist on the retro FPS formula, with a focus on exploration and epic scale.

Turbo Overkill

Strengths: Turbo Overkill is all about movement and style. You have a chainsaw attached to your leg that lets you slide and shred enemies, plus a grappling hook and a dash for incredible mobility. The combat is fast, brutal, and encourages you to chain kills for score. The levels are cyberpunk-themed with neon lights and plenty of verticality. The weapons are creative, like a revolver that can be thrown and a shotgun that fires explosive shells. It’s relentlessly fun and rewards aggressive play.

Trade-offs: The cyberpunk aesthetic is very different from Mouse P.I.’s noir cartoon. The game is extremely fast, which can be disorienting for some. The story is minimal, and the difficulty can be punishing on higher settings.

Who it suits: Players who love movement tech and want a game that rewards speed and style, similar to ULTRAKILL but with a more gritty, cyberpunk vibe.

How to Choose

Your choice ultimately comes down to budget and what you value most. If you want the closest combat match to Mouse P.I., ULTRAKILL is the clear winner—it’s a premium indie title, but worth every penny. If you’re on a tight budget, DUSK and Prodeus often go on sale and offer excellent value. For a more traditional retro feel, Ion Fury is a great pick, but be prepared for more exploration and less pure arena combat. Amid Evil is ideal if you want a fantasy setting, and Turbo Overkill is perfect if you crave extreme speed and style.

A common trade-off is between movement complexity and accessibility. Games like ULTRAKILL and Turbo Overkill have a steep learning curve due to advanced movement tech, while DUSK and Prodeus are more approachable. Also consider level design: if you prefer linear, combat-focused arenas, ULTRAKILL and Prodeus are better; if you enjoy exploring and finding secrets, Ion Fury and Amid Evil will satisfy.
