How long does the main story take to beat?

The main story of Mouse: P.I. For Hire is about 7–9 hours on a focused playthrough. This assumes you just follow the main objectives in order.

How much time to 100% the game?

For a full completionist run (all collectibles, side quests, etc.), expect roughly 14–16+ hours. In practice it can reach up to ~15–20 hours for the very thorough player.

How many missions are there?

The campaign has 24 main missions, numbered sequentially. These are the core cases you must finish. There are also about 15 optional side jobs, but they’re not counted in the 24 main missions.

How many side jobs are in the game?

There are roughly 15 optional side investigations. They are offered by NPCs (like Tammy, John Brown, Wanda, etc.) at specific times between main missions. You must accept each one before starting its associated mission, or it becomes permanently unavailable.

Is there a New Game Plus or mission replay?

No. The game has no New Game Plus and does not allow replaying past missions once completed. GameSpot and other guides make it clear there’s no chapter select – once you finish a mission and return to the hub, that level is locked and cannot be replayed. You must complete everything you want in one run.

What are the difficulty settings?

There are three fixed difficulties: Rookie (Easy), Detective (Normal), and Supersleuth (Hard). Rookie is very forgiving, Detective is standard, and Supersleuth makes enemies hit much harder. (In fact, on Supersleuth it’s recommended to carry extra healing cheese and use the best weapons, whereas on Rookie/Detective even basic health packs are usually enough.)

Can I replay missions to get missed items?

No. Once a mission is over, you cannot go back. As mentioned, the game’s design is “strict forward momentum” – after leaving a scene it stays locked. If you missed an item (safe, comic, etc.), you’d have to load an earlier save or start a new game. There is no post-mission replay feature.

How do I avoid missing side jobs?

Always talk to the NPCs in the P.I. Office before starting each mission. If an NPC is offering a side job, you need to accept it immediately. For example, Tammy’s side quest “Show Some Culture, Jack” must be taken before “Gumshoe in the Opera”. In general, check each client and pick up their quest in the hub; otherwise that content is lost.

What is the fastest way to beat the campaign?

Speedrunners skip all side content and use tricks. One known exploit: the very first mission loads the final scene, so by quickly loading and exiting you can warp to the end. Players have done runs in under 20 minutes using that glitch. Without major glitches, an any% run (main missions only) has been done in around 3–5 hours. The key is to skip all optional objectives and run straight through, using any discovered sequence breaks.

Is this game worth playing for its length and content?

Reviews say yes. Many consider it to offer great value at its 7–9 hour story (plus extras) length. Kotaku praised it as “one of the best first-person shooters” after a ~12-hour playthrough. Insider Gaming called its price-to-content ratio “strong return”. Overall, if you enjoy classic FPS games and its unique cartoon style, most players find the content justifies the time investment.

Mouse: P.I. For Hire is a 2026 cartoon‑style first-person shooter in which you play a detective named Jack Pepper. The game was released on April 16, 2026 across major platforms. Players often ask about its length and content. In this guide we cover the main story duration, completionist time, campaign missions, optional side jobs, difficulty modes, replayability, and overall value.

How Long To Beat Mouse: P.I. For Hire Main Story (Average Playtime Explained)

The main story of Mouse: P.I. For Hire is relatively concise. Most sources agree it takes about 7–9 hours to beat the campaign if you only follow the main objectives. GameSpot reports that a straightforward playthrough should wrap up in roughly 7–9 hours. Similarly, NeonLightsMedia’s guide lists the “Main Story Only” time as 7–9 hours. This estimate assumes you move quickly from mission to mission without lingering on puzzles or exploring every nook. In short, expect a focused run through Jack Pepper’s case to land in the high single digits of hours.

Mouse: P.I. For Hire Completionist Time How Long For 100% Completion

If you want to achieve 100% completion, the time investment rises significantly. Completionists who track down every collectable, complete every side quest, and explore the hub area will spend around 14–16 hours. GameSpot notes that seeking out everything pushes playtime into the 14–16 hour range. Likewise, NeonLightsMedia cites a similar figure of 14–16 hours for a full completionist run. In practice, finishing all main cases (7–9h) plus all optional content roughly doubles the playtime. Guides and player reports suggest realistic completionist times can even stretch into the upper teens (around 15–20 hours) depending on thoroughness.

Mouse: P.I. For Hire Campaign Length Breakdown (7–9 Hours vs 15+ Hours)

In summary, Mouse: P.I. For Hire has two broad playtime brackets. A clean playthrough focused on the story alone is about 7–9 hours. In contrast, a completionist run grabbing all collectibles, side jobs, and collectibles is roughly 14–16+ hours. In fact, one guide estimates that thorough players will spend “somewhere between 10 and 20 hours” overall. For its $29.99 price point, this is viewed as a solid length. As Insider Gaming’s review summarized, at that price the game offers “strong return” even calling it “the best pound-for-pound game of 2026”.

All Missions List in Mouse: P.I. For Hire (Complete Case Order Guide)

The campaign consists of 24 main story missions in a fixed sequence. For example, the first three missions are “Big Mouse, Little Hope”, “The Vanishing Act”, and “Gumshoe in the Opera”. In total, there are 24 cases to complete. Official guides list them all in order. NeonLightsMedia notes that the story actually “comes full circle, starting and ending with ‘Big Mouse, Little Hope’”.

(Indeed, the last mission shares the name with the first.) So the game begins with Big Mouse, Little Hope, then The Vanishing Act, Gumshoe in the Opera, and so on through Jack Squat, The House of the Empty Mouse, and finally Fair Enough back to Big Mouse, Little Hope. In other words, expect 24 sequential levels covering Jack’s case from start to finish.

How Many Missions Are in Mouse: P.I. For Hire? Full Campaign Overview

There are 24 main missions in the campaign. These are the chapters you need to complete to see the story through. (Many guides list “24 main missions” explicitly.) In addition to the main cases, the game features a number of optional side jobs assigned by NPCs in between. In total there are roughly 15 side missions that tie into the story flow. (These are not counted in the 24. They unlock only at specific points more on those below.) The main campaign is linear and takes place fully over those 24 missions. As noted, the narrative loops back around, beginning and ending with “Big Mouse, Little Hope”.

Mouse: P.I. For Hire Full Mission List With Side Jobs Explained

The full mission list includes all main cases and their linked side quests. GameSpot’s breakdown shows every mission name with any associated side jobs listed underneath. For instance, before the mission “Gumshoe in the Opera,” Tammy in the hub will give you the side quest “Show Some Culture, Jack”. After “Bandel’s Laboratory,” a note appears in the office unlocking the “B.A.N.G.” side job.

Every optional case is tied to one of the 24 main missions, and guides like GameSpot/NeonLightsMedia attach each side job to the mission where its objective is found. Consult those mission lists for full details. In short: complete each main mission, and whenever you see an NPC offering a side job beforehand, take it that way you’ll retrieve the necessary item (the unlock trigger) during that mission.

All Main Missions in Mouse: P.I. For Hire Ranked by Difficulty

The game itself does not provide an official difficulty ranking of missions. However, difficulty generally ramps up as you progress. The early investigations (like “Big Mouse, Little Hope”) introduce mechanics gently, while the final missions pose the greatest challenge. For example, GameSpot’s list flags “Jack Squat” with a “Critical Warning” (starting it permanently locks you out of the hub), indicating a major endgame test. On higher settings (Supersleuth), later missions require careful play GameSpot even recommends carrying extra healing (cheese) in those cases. In practice, boss encounters and large enemy fights peak in the final chapters.

If you find a mission extremely tough, consider switching to Detective or Rookie mode, or reloading a save before difficult sections. (GameSpot’s tips explicitly say Rookie/Detective are very forgiving, while Supersleuth demands stockpiling healing.) In short, expect difficulty to progressively increase, with “Jack Squat” and the bonus “House of the Empty Mouse” standing out as the toughest missions.

Mouse: P.I. For Hire Side Jobs Guide Unlock Conditions and Missables

The optional side jobs are offered by NPCs at the hub between certain missions. It’s crucial to accept them at the right time, or they become missable forever. NeonLightsMedia warns that “if you do not talk to [the NPCs] and secure the job before starting the next main level, you will permanently miss the quest”. Likewise, GameSpot explains that each side job’s unlock condition is listed (usually an NPC and timing) in their mission breakdown. For example, Tammy must give you “Show Some Culture, Jack” before you head into “Gumshoe in the Opera”. John Brown appears before “A Bit of Curd and Pepper,” Wanda appears for a mission later, etc.

The key tip: always scan the office for talkable characters before jumping into a mission. Failing to do so will close the door on that side job.

In sum, side quests unlock via NPC dialogue (or finding notes) in the hub talk to all clients and grab their quests before starting the associated main mission.

Can You Replay Missions in Mouse: P.I. For Hire? What You Need to Know

No once you complete a mission, you cannot go back and replay it in the same save file. Both guides make this clear. GameSpot says the game is “stingy about revisiting areas,” so wrap up all objectives before leaving a level. NeonLightsMedia similarly emphasizes that the game runs on “strict forward momentum”: once you clear an area and return to the P.I. Office, that level is permanently locked down. Any collectibles, clues, or side-job items you didn’t grab are gone unless you reload. In short, there is no mission-select or replay feature in-game. You must complete everything you want in a mission before exiting it, or else you’ll have to replay from an earlier save (if available).

Does Mouse: P.I. For Hire Have New Game Plus Mode or Replay Options?

No, there is no New Game Plus or any special replay mode. GameSpot explicitly confirms that finishing the campaign “does not unlock any additional modes” beyond the standard difficulties. NeonLightsMedia similarly states that there is no New Game Plus once you finish the story, the game ends. The only variations after beating the game are choosing a different difficulty (Rookie, Detective, or Supersleuth) on a new playthrough. So you cannot restart with powered-up gear or carry over progress.

Plan accordingly, since missed items or quests won’t be salvaged later. Once the credits roll, you’re done the only way to replay content is by manually starting a new game or reloading earlier saves, as neither mission replay nor NG+ are supported.

Mouse: P.I. For Hire Difficulty Settings Explained (Rookie to Supersleuth)

The game has three fixed difficulty levels:

Rookie (Easy): Enemies are less aggressive, and you recover faster. On Rookie mode you can generally rely on basic health pickups GameSpot notes that on Rookie “the amount of damage enemies deal is rarely more than you can handle”. It’s recommended for players who want a relaxed experience.
Detective (Standard): The default setting, offering a balanced challenge. Enemies hit harder than Rookie, but still reasonably fair. Most players will use this for their first run.
Supersleuth (Hard): For veterans. Enemies deal significantly more damage and ammo/heals are scarcer. GameSpot specifically advises that on Supersleuth (or during tough boss fights), you should stock up on extra cheese (the healing item) to survive. Likewise, you’ll want to optimize your weapons (for example, using the shotgun on large foes and the Devarnisher on shielded enemies, as mentioned in guides). In essence, Supersleuth mode makes combat more punishing, so use it only if you want maximum challenge.

These three modes are the only difficulty options completing the game unlocks no new modes beyond toggling between Rookie, Detective, and Supersleuth.

Fastest Way to Beat Mouse: P.I. For Hire Campaign (Speedrun Tips)

Speedrunning Mouse: P.I. For Hire is still new, but the strategies are straightforward. To finish quickly, skip all optional content (side jobs, collectables, even most dialogue) and press on through the missions. Players have discovered major shortcuts as well: notably, the first mission is essentially the final one, so by repeatedly loading and exiting you can warp straight to the end. Reddit speedrunners report that the intro mission is a version of the final mission, allowing an “any%” glitch that reaches the final boss almost immediately.

Those glitch runs can clock in under 20 minutes. In a more normal run (no major glitches), early times are around 3–5 hours: one runner posted a 4:33:12 full-game time and expected sub-3 hours once optimized.

General speed tips include: stick to the main path and ignore side objectives entirely, use fast travel (propeller wings, grappling hook) to zip through areas, and exploit any clipping or load tricks players find. Also, carry minimal inventory to save time (sell unwanted guns in hub). In short, there’s no official speedrun category yet, but skip side quests and use available glitches to minimize playtime.

Tips to Complete All Missions in Mouse: P.I. For Hire Without Missing Content

For a thorough playthrough, meticulous saving and exploration are key. As noted above, you cannot backtrack once you leave a level. So GameSpot advises saving in the office before each mission (“Save at your office after every level”) to preserve progress. NeonLightsMedia likewise strongly recommends dropping a manual save before every mission. This way, if you accidentally leave something behind (like a hidden collectible or an NPC), you can reload and grab it.

Always scan every room for clues, secrets, and power-ups before exiting. Use a checklist: many guides (and this article’s mission list) serve as definitive checklists to mark off each newspaper, card, comic, side-objective, etc. In fact, NeonLights explicitly says to keep a mission list up and “leave no stone unturned” while playing. Talk to all side-job givers before missions, search vents and high places for secrets, and exhaust dialog options at the hub. As GameSpot notes, missing even one hint or collectible can’t be fixed later. In summary: save often (especially in the P.I. Office between cases), explore every area completely, and refer to mission guides so that nothing is accidentally skipped.

Mouse: P.I. For Hire Mission Order Guide for Beginners

Mouse: P.I. For Hire is a linear, hand-holding experience story-wise. Beginners should simply follow the missions in the order given. Numerous walkthroughs list the cases in chronological order as a checklist. In other words, start with “Big Mouse, Little Hope” (Case 1), then do “The Vanishing Act” (Case 2), then “Gumshoe in the Opera” (Case 3), and so on. There’s no way to get lost or take the wrong branch each case unlocks the next. If you want guidance, use NeonLightsMedia’s “exact chronological mission list” as your roadmap.

That will tell you when each side job should be picked up as well. The main takeaway: play the 24 missions straight through and talk to any side-job NPCs as you encounter them. New players need not jump between missions just press forward in the intended order.

Is Mouse: P.I. For Hire Worth It Based on Length and Content?

For most fans of classic shooters, the answer seems to be yes. Mouse: P.I. For Hire delivers a unique, polished experience that many find worth its playtime. Critics praised its charm and gameplay: Kotaku’s review declared it “one of the best first-person shooters I’ve played in many years” after about a 12‑hour playthrough. Reviewers highlight the gorgeous hand-drawn noir art, variety of levels, and satisfying gunplay. Combined with 7–9 hours of main story (and ~15+ for completion), it offers solid bang for the $30 asking price. According to one guide, that runtime at $29.99 is a “strong return,” even naming it the “best pound-for-pound game of 2026”.

In short, if you enjoy cartoonish FPS action, the general consensus is that the length and content of Mouse: P.I. For Hire justify the purchase, provided you don’t mind replaying for collectibles (since there’s no NG+ or easy replay). With an 81 Metacritic score and happy players, it’s widely regarded as a worthwhile game.
