This is a short tutoral for creating kit files.
The following describes how to customize the main menu guys. The same steps can also be used to create AI kits.
Go to steamapps/common/Ground Branch/GroundBranch/Content/GroundBranch/DefaultLoadouts
Make a backup of MainMenuGuy_01.kit and MainMenuGuy_02.kit
Create a kit in the “Customize Operator” screen.
Open NoTeam.kit in text editor and copy paste the relevant entries to MainMenuGuy_01.kit and MainMenuGuy_02.kit. The .kit files are JSON files.
Use an editor that has JSON support for more comfort (e.g: VS Code or Intellij IDEA). The general syntax of JSON is described on Wikipedia.
ItemBuild references in the JSON need to removed.
In the main menu use console command restartlevel to apply your changes without restarting the game.
The console can be opened with the NumPad * key.
