Launcher command line arguments

What are command line arguments

Command line arguments, or short CLI Args, are used to tell a program to do a specific task or behave in a certain way.
Arguments generally override values set in the launcher config - but they don’t get saved to it.

Using command line arguments

You can create a shortcut of the IW4x Launcher by right-clicking it and selecting “Create shortcut”. You can then right-click the shortcut, select properties and append the arguments in the Target field like this:

E:\iw4x\iw4x-launcher.exe --help
