To edit difficulty settings in OpenCAGE navigate to View > Configuration Editors > Core Game > Difficulty Settings.
From here you will be presented with a variety of modifiers applied to various game systems depending on the difficulty level selected in-game, including alien configs, character senses, character attributes, and viewcones.
Pick a difficulty from the dropdown at the top of the window. Its modifiers are on four tabs: Alien Config, Character Senses, Character Attributes and Viewcones. The Character Senses and Character Attributes tabs each have a dropdown for the character type, and the Viewcones tab has one for the viewcone set.
There is no Save button: changes are saved as you make them. A difficulty's file can name another difficulty as its template. Where the selected difficulty doesn't set a value itself, the editor shows the value from its template. When the editor opens it saves every difficulty, writing the values each one inherits into its own file. A box with no value in the difficulty or any of its templates is greyed out and isn't saved.
The game reads these settings when it starts, not when it loads a level, so a change reaches it the next time it starts. With Live Link connected, and the game started with the Debug Menu on, each change also has the running game read the settings again, and every character takes them up straight away (the difficulty you're playing stays as it is), as the line at the bottom of the editor says.
