MOUSE: P.I. For Hire: How to Clear Jack Squat – Full Walkthrough

MOUSE: P.I. For Hire players should treat Jack Squat as a main-story chapter sweep, not a speed section. The safest way through it is to clear each combat space before looting, leave every warp pipe until you are sure the room is finished, check every side path and safe as you find it, and slow down for the assassin fight instead of trying to burst it down. Public guides are consistent on the big points: Jack Squat is a campaign chapter, it is heavily tied to collectibles, and it includes a notable Hitman encounter.

If you are cross-checking different walkthroughs, one useful detail is that Jack Squat is sometimes associated with or labeled as Office Ruins. That matters because collectible routes and creator videos do not always use the same wording, and part numbers in YouTube series are not reliable enough to use as a map substitute.

What Jack Squat is really asking you to do

This chapter seems to be one of the denser cleanup-friendly missions in MOUSE: P.I. For Hire. Community coverage puts a lot of emphasis on “all collectibles” runs here, which usually means the level has enough hidden pickups and route splits to punish players who rush straight toward the next obvious objective. That is the main trap in Jack Squat: it looks like a straightforward story push, but it plays better when you move room by room and assume any optional-looking detour may matter.

There is also some disagreement in current guide terminology. One source may talk about schematics and a comic, while another talks more broadly about cards, newspapers, toys, or other chapter collectibles. Until a fully standardized item list is widely available, the practical answer is simple: do not rely on names alone. If it is a side nook, a safe, a short platform branch, or a dead-end ledge, check it before you progress.

Best route through Jack Squat

Clear enemies first, then loot

Jack Squat works better when you separate survival from exploration. If enemies are still active in a room, finish that problem before you start hunting for pickups. This keeps you from getting tagged while staring into a corner or opening a safe, and it also makes it easier to remember whether a room is actually finished.

A good mental loop is: enter area, identify angles where enemies can shoot from, clear those angles, then sweep the edges of the room. In a noir-styled shooter like MOUSE: P.I. For Hire, getting impatient and pushing the center line is usually what creates messy damage trades. If you play corners and use short peeks, the chapter becomes much more manageable.

Treat every warp pipe like a point of no return

The most useful habit in this mission is to treat a warp pipe as the last thing you touch in a section. Even when a pipe is not technically locking you out, it often changes your orientation enough that cleanup becomes annoying. Before entering any pipe, do a quick room check:

• Look behind the pipe entrance, not just in front of it.
• Check upper ledges and short side platforms.
• Open any visible safe before moving on.
• Confirm you are not leaving a small side room unexplored.

This one habit solves most missed-item problems in Jack Squat. Players usually lose collectibles here not because the game hides them brilliantly, but because the next traversal device is visually louder than the side content around it.

Open safes immediately

If you see a safe, interact with it as soon as the room is secure. Do not tell yourself you will come back after the next fight. In collectible-heavy chapters, safes are exactly the kind of object that gets forgotten once the route loops, the camera flips, or a warp pipe sends you to a new angle. Opening them immediately also gives you a cleaner mental map: safe opened means room checked.

This is especially important in Jack Squat because guide language around collectibles is still inconsistent. Whether the chapter is tracking schematics, comics, cards, or a broader mix, the player-side solution is the same: resolve every interactable the moment it is safe to do so.

How to avoid missing schematics and other collectibles

If you are going for 100%, do not wait until the end of the chapter to start caring about collectibles. Current coverage strongly suggests Jack Squat has enough hidden items to justify dedicated cleanup videos, which is a good sign that blind rushing is the wrong approach.

• Use a clockwise or counterclockwise sweep of each room instead of wandering randomly.
• Check dead ends before objective markers.
• After every combat section, pause for a visual scan of floor level, waist level, and any raised route above you.
• If a route splits into traversal and loot, assume traversal progresses the chapter and leave it for last.
• If you are comparing guides, search both Jack Squat and Office Ruins so you are not missing the same chapter under two labels.

That last point matters more than it sounds. Some players think they are looking at the wrong walkthrough when the naming changes, when really they are seeing the same mission framed by a different area title.

Water platforming: slow down and make it a routing check

The ugly mistake in Jack Squat is treating the water platforming as filler between firefights. It is not. This is where players overshoot jumps, miss side ledges, or rush into the next transition without checking for a collectible branch.

The reliable method is to stop fully on each platform, reset your camera, and line up the next jump from the center instead of the edge. Short, controlled movement is safer than trying to preserve speed. If you are on controller and keep over-correcting, a small sensitivity drop can help more than repeated retries. On mouse and keyboard, avoid big wrist flicks between jumps; the section is easier when you keep camera movement tight and deliberate.

Also, do a quick scan before taking the obvious next jump. Water sections are classic places for developers to tuck a pickup onto an offset platform or a side route that looks decorative at first glance. Even if the chapter’s exact collectible count is still being standardized by the community, the route logic points the same way: platform carefully, then search before advancing.

How to handle the Hitman assassin fight

Published walkthrough coverage specifically flags a Hitman encounter in Jack Squat, so it is worth saving your focus for that fight instead of bleeding resources earlier. Without leaning on unverified move-by-move details, the most dependable approach is to make the fight slower and cleaner rather than trying to win a straight damage race.

• Use cover and re-peeks instead of standing in open lanes.
• Prioritize survival over constant fire; the assassin fight is exactly where greedy damage usually gets punished.
• Strafe and reposition after short bursts rather than holding forward pressure.
• Punish recovery windows, then reset your angle.
• If the arena has multiple sightlines, keep rotating so you are not giving the enemy easy repeat shots from the same line.

The reason this works is simple: boss-like enemies in FPS chapters are most dangerous when the player turns the fight into chaos. Jack Squat already asks for methodical exploration, and the same pace helps in combat. If an attempt is going badly, stop forcing offense and take back space first. A controlled reset is usually better than squeezing out one more risky burst.

If you entered the fight while still unsure whether you cleared earlier rooms, that is another reason the chapter feels harder than it should. Missing a safe or schematic is frustrating on its own, but it also creates the urge to rush the boss so you can go check later. Do the cleanup first whenever the route allows it.

If your walkthrough video does not seem to match your game

Do not assume your run is wrong just because a creator labels Jack Squat as Part 18, Part 20, or Office Ruins. Community series cut chapters differently, and public numbering is not canonical. Match by environment, warp pipe order, safes, water platforming sections, and the Hitman encounter instead of trusting part titles alone.

If your collectible total is short, the most likely misses are the same ones most completionist chapters punish: a safe left unopened, a side ledge ignored before a warp pipe, or a branch during the water section that looked cosmetic on the first pass.
