Steam Branches – Arma 3
Overview
Arma 3 is distributed as several branches on Steam.
These branches are accessible by opening the application Properties in Steam client. In the BETAS tab, you'll find a drop-down menu with publicly available branches. Some branches require an access code to be input before appearing the list. Those codes are shared via channels such as Twitter and the forums when appropriate. You may need to restart the Steam client to see recently created branches.
After selecting a branch, Steam client will begin downloading the differences in data. It can be recommended to do a local file verification afterwards to be sure the correct update was downloaded. Note that Steam client does not allow you to maintain multiple parallel branches on your hard drive. Our Game Updater tool does allow this for certain branches.
