Bohemia Interactive released the Arma 3 Launcher with the 1.24 (Bootcamp) game update. This Launcher will start automatically when launching arma 3 in steam. The Arma 3 Launcher allows you to arrange mods on your computer into presets and to launch into the game and servers running those presets. The Arma 3 Launcher is also directly connected to the Arma 3 Steam Workshop allowing you to download and update mods which are running on servers you want to join if the mods are offered on the Steam Workshop. Detailed information from the game developer about the Arma 3 Launcher can be found in the BIS Wiki.

In this section we will be covering Arma 3's default launcher setup and mod preset creation. You can also find this guide in the Ordnance Office


If you have not already downloaded the required mods by subscribing to the Official 29th ID Arma 3 Steam Workshop collection, please do so now.


Open ARMA 3 from your Steam games library. When you fire up the game through Steam, it will bring up the Arma 3 Launcher.


Launcher Options

At the top right of the launcher window you will find the word OPTIONS next to a gear icon; click that. Then click: Launcher Options.

From here you can select:

  • Default language preference,
  • Launcher action after game start,
    • As the launcher does use a nontrivial amount of resources, we recommend selecting Close launcher after clicking play.
  • Default page upon launcher start,
    • We recommend the selecting either of Mods or Servers selections.
  • Theme,
  • Weather to allow analytics to be pushed to the game developers, and
  • Legacy compatibility settings which you likely will never need.

Mod Options

This options section allows you to tell the launcher where to look in your folders for custom mods or mods otherwise downloaded from a source that is not the Steam Workshop.


We do not use any custom mods not found on the Steam Workshop. It would be exceedingly rare for us to ask you to use this section during your time in the 29th for 29th events or functions.


From the menu on the left click on PARAMETERS, here we can see a list tree of several different sections and options within. Hovering your mouse cursor over the specific option item will display a tool tip with a description of the parameter's function.


Detailed information regarding the launcher parameters can be found on the BI Community Wiki at Arma 3 Launcher.


Here we can make a few selections which will speed up the loading process and get us in game faster. Check the boxes for

  • No Splash
  • Skip Intro


The only option we recommend as a universally set option is to enable the World option (check-box) and select 'Empty World' from the drop down list. This will expedite loading.


Detailed descriptions of each of the advanced options can be found on the BI Community Wiki at Arma 3 Launcher: Advanced Parameters. If you are interested in adjusting any of the advanced options you do so at your own risk; be sure to read the documentation first!
