MONOCHROME Roblox Full Walkthrough: Four-Key Escape Guide

Scope and Evidence

Editorial review: October 8, 2026. This walkthrough covers the Part I four-key escape described in September gameplay sources. The official listing now includes Part 2; fresh Part 2 routes and puzzle mechanics have not been checked here. The official description still specifies four keys and one code. The scene image is official promotional media, not an annotated route capture.

Part I Escape Checklist

Use these steps as a written companion to the reviewed Part I walkthroughs. Follow the visible interaction prompts if your session differs.

• Orient in the elevator lobby: locate the elevator, four-lock panel, keypad, and boarded DO NOT ENTER doorway.
• Use the doorway interaction to remove the boards and open the route downstairs.
• Search one corridor branch at a time, checking interactable dressers and drawers for keys.
• Leave searched drawers open where possible and keep a clear route back to the lobby.
• Insert recovered keys at the elevator panel and check progress against its four indicators.
• Record the four-digit clue visible in your run and enter those digits at the keypad.
• Check both lock requirements, then use the elevator interaction when available.

Open the Downstairs Route

The reviewed September walkthroughs begin in an upstairs elevator lobby. The boarded doorway marked DO NOT ENTER opens the route into the lower corridor network. Those sources describe a hold interaction to remove the boards. Use the prompt in your build rather than assuming a particular keyboard or mobile control.

Before entering the maze, identify the stairs or return route. This gives you a reference point when the corridors begin to look alike.

Search Furniture and Track Keys

September sources describe key searches in dressers and drawers. Clear one connected section before moving to the next. Leaving searched drawers open provides a visual marker where the session preserves that state.

Return to the four-lock panel when the route is safe, install recovered keys, and count the green indicators. The sources do not establish four guaranteed named spawn rooms. This guide therefore recommends a repeatable sweep instead of fixed coordinates.

Read the Clue in Your Run

The reviewed sources describe a four-digit clue displayed on a slip or pale block in the lower maze. Record the digits exactly as they appear, including any leading zero, and use that clue for your keypad attempt.

Different reported runs contain different numbers. That evidence does not establish a universal code or a documented rule for how often the number changes. Entering a published example is less reliable than checking the clue in your session.

Manage Corridor Encounters

The reviewed gameplay sources use wardrobes as temporary hiding places. If a threat interrupts your search, stop the furniture checks and use the available hiding or retreat route. Resume from the last unchecked section when it is safe.

We have not verified a complete monster-sensing rule, noise threshold, or guarantee of item persistence after death. After an interruption, inspect your actual key-panel and keypad state before continuing.

Check the Exit

The reviewed escape sequence requires both the four installed keys and an accepted keypad entry. If the elevator is still closed, inspect each requirement separately: count the green indicators, compare the keypad digits with your clue, and check the elevator prompt.

Missing keys are a reason to revisit unchecked furniture. Four installed keys with no exit are a reason to check the code and interaction state. A closed elevator by itself does not prove that the keypad rejected the number.

Using This Guide as a Companion Resource

The October editorial review updates the scope and wording; it is not a claim of a new playtest or Part 2 completion.
