Portal Revolution is a fan mod the size of a full sized expansion that serves as a prequel to Portal 2, with eight hours of gameplay, brand new mechanics and original fully voiced characters.
It came out on January 6th, and recently was given an update that allows players to invert their mouse controls, so they can play in a way more comfortable for them. This guide will show you exactly how to find and change the setting that allows this inversion.
How To Invert Mouse Guide
This guide starts where every good story starts, at the main menu. Alternatively, you can pause your game at any point to see this menu. Click the highlighted “Options” button to be taken to the options menu.
You will be then greeted by this menu, with a view on the top showing the different tabs responsible for showcasing different options present in the game.
We need to click the “Keyboard & Mouse” tab, the second one on the left.
From there we will navigate to the “Invert Vertical Look” option, and click the drop down arrow.
From there we choose the “Enabled” option, and then we’re all done. This was a quick way to invert mouse aiming in-game. Settings save automatically so you can just exit out of the menu and resume your puzzle-solving adventures!
