BattlEye is anti-cheat software used by Arma 3. BattlEye initialization progress is presented on the progress bar.
BattlEye Status

  • Enable BattlEye anti-cheat software - When enabled (default), it will launch BattlEye anti-cheat service before launching Arma 3.
  • BattlEye Log Messages - Displays the BattlEye messages and status updates. Messages can be copied to a clipboard.

NOTE: BattlEye EULA needs to be accepted. If not, the service is not launched.


Servers page contains an integrated server browser. It contains five tabs which contains a specific set of Arma 3 Servers.

  • Favorites - displays only Arma 3 servers you've marked as a favorite (with a star).
  • Recent - displays the servers you've played on recently.
  • Friends - the servers where you Steam friends play right now.
  • Internet - all the reachable internet servers.
  • Units - the servers related to Arma 3 Units that you are member of.

On each tab you can find the filter bar on the top, where you can enter a search phrase or filters or use the "Filters" button to display a dialog where you can edit your filters. If the filter is active, its icon and the frame will in gold. The server counter next to the filter bar shows number of displayed servers and total number of servers; when the filter is active, these numbers may be different.

Each game server is represented by a row in the list. You can join the server by clicking on "JOIN" button that will appear when you move your mouse to that row. (If the server can't be joined, because it's locked the lock symbol will appear instead.). Clicking anywhere else on the row will expand it and display more information about the server (e.g. server version, server address, required DLCs).

When you click on the JOIN button a dialog with required mods is displayed to you. On the top it displays the basic information about the server (you can click on it to display more). The middle part of the dialog displays required and optional mods (and also the mods you have currently selected, but that can't be used on the server). When you click on SETUP MODS AND JOIN button Launcher will automatically load the mods it recognizes and subscribes you Steam Workshop to the ones that you don't have. (Some servers might be missing a Steam Workshop identifiers for the mods, so Launcher might have a hard time detecting the right mod or the mod might not be available on the Workshop at all.) You can change what happens when you click the button by changing the action for each of the mods in the list of mods above it. KEEP CURRENT SELECTION AND JOIN button will connect you to the server without any changes to mods you have enabled on MODS page.

The commands displayed at the bottom:

  • Host server - starts the game and start the game server.
  • Direct connect - let you connect to the server by manually entering it's address and game port.
