For Hire – All Secret Door Codes for The Depths"},"content":{"rendered":"

Deep within the labyrinthine corridors of MOUSE: P.I. For<\/a> Hire lies a secret that has become a topic of quiet conversation among players who have dug past its main case files. It\u2019s a locked door, an unassuming obstruction in the late-game zone known as The Depths, that offers no clues to what lies beyond. Unlike other investigative puzzles in this noir-inspired detective adventure, this particular mystery isn\u2019t something your mouse sleuth can logically deduce from the environment. The door demands a simple, four-digit numeric code, but the game purposefully scatters these sequences across its world, offering them through environmental clues, NPC dialogues, or lore snippets that are easy to miss and impossible to recover. If you didn’t meticulously jot them down during your travels, solving it becomes an exercise in pure, frustrating guesswork. This guide is your definitive key ring, consolidating every known passcode, detailing the precise path to this enigmatic gateway, and explaining the strange rewards that await those who know the right numbers.<\/p>\n

Locating the Locked Door in The Depths<\/h2>\n

Before you can even attempt to crack the code, you must first find the door itself. This area is not accessible from the start of the game or even the early stages of The Depths. It is gated behind specific narrative progress, making it a truly end-game secret for those who have nearly completed their rodent investigation. The single, non-negotiable requirement to even make the journey is having the quest titled “Shrewd Shrews” actively in your log. This quest serves as the narrative key that unlocks the physical path forward.<\/p>\n

Assuming you have this quest, the route is as follows: enter The Depths level and progress through it as you normally would, navigating its industrial, subterranean platforms and dealing with the usual environmental hazards and enemies. Your critical landmark is a massive, industrial elevator\u2014a prominent set piece that is hard to miss. Ride this elevator down to its lowest stop. Upon exiting, do not proceed forward along the main path. Instead, immediately take a hard left turn. This leads you down a side passage that feels intentionally separate from the primary critical path. Continue moving left, hugging the wall, until the environment shifts from open caverns to what appears to be a derelict facility. You will see a free-standing, simple building structure. Approach it, climb the short set of stairs leading to its entrance, and walk through the door.<\/p>\n

Inside, you’ll find a small, stark room with a singular point of interaction: a keypad or code-input device next to a heavy, sealed door. This is your destination. The room offers no other context, puzzles, or enemies. Its entire purpose is to serve as the interface for the secret you are about to unlock.<\/p>\n

The Complete List of Functional Codes<\/h2>\n

Here are all the currently verified, functional four-digit codes that successfully open the secret door. Each code unlocks a different experience; entering them is not a one-and-done activity. You can input each code sequentially to see what each one reveals<\/a>.<\/p>\n
