Meccha Chameleon Guide: Forcing Inverted Mouse Controls
It's frustrating when you accidentally stare at the floor instead of the ceiling, but a tiny file edit will fix your camera right up.
Right now, version 2.5.0 doesn't have an official menu toggle for the Y-axis. If your brain defaults to flight controls, playing a chaotic round of hide and seek feels nearly impossible. You'll hear your friend running above you, pull back on the mouse, and suddenly you're inspecting the carpet while they tag you. It's a huge relief to finally point your camera exactly where you want it under pressure, and you don't need to wait for a patch to fix it.
Tracking Down the Config Folder
Locating the game's save data is your first step. You don't need any weird third-party modding tools for this part.
Open File Explorer on your PC. Click the address bar at the top, paste in %LOCALAPPDATA%\Chameleon\Saved\Config\Windows, and hit Enter. If an error pops up saying the folder doesn't exist, you just haven't booted the game yet. Launch it once, close it completely, and those required folders will appear automatically.
Building Your Settings File
Once you open that Windows folder, you need to create a specific document that tells the engine how to handle your mouse inputs. Right-click any empty space in the folder, pick New, and click Text Document. Name this file exactly Game.ini.
The File Extension Trap
Windows loves hiding file extensions by default. If your settings do this, you'll accidentally name your document Game.ini.txt and the engine will completely ignore your hard work.
To fix this, click the View tab at the top of File Explorer, choose Show, and make sure "File name extensions" has a checkmark next to it. Alternatively, just copy any existing .ini file already sitting in that directory. Paste it, rename it to simply Game, open it up, and clear out all the old text inside.
Dropping in the Code
Now that you have a blank configuration file ready to go, you just need to drop in the raw input commands. Open your Game.ini file using Notepad. To invert your vertical look, paste these two exact lines into the document:
[/script/engine.playercontroller] InputPitchScale=2.5
If you want to go all out and invert your horizontal look on the X-axis too, add a third line right below the pitch scale:
InputYawScale=-2.5
Save the file and close Notepad.
Securing Your Changes
If you start the game right now, the engine will probably overwrite your file and delete everything you just did. You need to lock it down so your custom inputs stay put.
Right-click your Game.ini file and select Properties. Find the Attributes section at the bottom, check the box labeled Read-only, and click OK. This explicitly blocks the game from touching or removing your custom modifications.
Now you can jump back into a lobby and actually look at the ceiling without fighting your own hands. Getting your controls comfortable turns the focus back to the fun of outsmarting your friends. Whenever the developer eventually patches an official toggle into the user interface, just uncheck Read-only, delete your Game.ini file, and set up your preferences normally.
