Installing your Mods

Mods in ArmA3 are by default read from two locations;

• the ArmA 3 main directory

  ...\Steam\SteamApps\Common\ArmA 3

• and the "My Documents\Arma3" folder.

  C:\Users\[YOURNAME]\Documents\Arma 3

Installing to the Arma 3 directory.
By default this is located in:
32-Bit - C:\Program Files\Steam\Steamapps\Common\ArmA 3
64-Bit - C:\Program Files (x86)\Steam\Steamapps\Common\ArmA 3

Extract your @mod_folder here. After extraction it should look like this:

...\Steam\Steamapps\Common\ArmA 3\@Mod_folder_1\Addons\[mod files (.pbo & .bisign)]

Installing to the "My Documents\Arma3" folder.
After extraction, your folder setup could than look like this:

C:\Users\[YOURNAME]\Documents\Arma 3\@Mod_folder_2\Addons\[mod files (.pbo & .bisign)]

It is also possible to set custom mod locations. This is best done with a launcher.

Userconfig folder
If a mod comes with a "userconfig" folder, place it into your Arma 3 main directory so it should look like this:

...\Steam\steamapps\common\Arma 3\userconfig

You may already have a "userconfig" folder from other addons and/or mods in which case it is safe to merge the contents from this archive.

Launching your Mods with Official ArmA3 Launcher

Using the Official BIS ArmA 3 Launcher
To start the launcher click Play on Arma 3 in Steam. You can install mods, create Mod Presets and configure your game startup options.
The BIS Launcher supports Steam Workshop items, as well as local files (e.g. Armaholic™ mod downloads and other non-Steam Workshop mods). For more information on the Official launcher, check the BIS Wiki here.

To install a mod:

1. Click on the Mods tab
2. Click on the import local mod button
3. Select your desired mods (Select multiple mods with Ctrl+LMB)
4. Save your mods as a Preset for future use
5. Click Play
6. To launch the game with a saved Mod Preset or unmodded, you can click on the arrow on the right of the Play button

Click on an image to expand:

• Also, Crtl+Shift+P with the BIS Launcher open will quickly start the game unmodded.
• Here's another simple tutorial on using the BIS launcher.

You can also enable and disable Mods in game - ArmA 3 Main Menu >> Configure >> Expansions. This will require you to restart your game.

Launching your Mods with Startup Parameters (Steam & shortcut methods)

Startup Parameters via arma3.exe/arma3server.exe shortcut
Right click on the arma3.exe and create a shortcut. Right click on the shortcut, open its properties.
At the end of the target line, paste -mod=@mod_name like this:

"C:\Program Files\Steam\steamapps\common\arma 3\arma3.exe" -mod=@mod_name

and if you want to add multiple mods, separate them with ";"

"C:\Program Files\Steam\steamapps\common\arma 3\arma3.exe" -mod=@mod_name;@mod_name2

Click here for more information on Arma 3 startup parameters.

Launch Parameters via Steam
You can add an Arma 3 Startup Parameter to Steam, in order to do so right-click on ArmA 3 and click Properties and then Set Launch Options.
In the window that opens enter in the following:

-mod=@your_mod_folder_name

For using multiple mods you would then do so like this:

-mod=@mod_name;@mod_name2;@mod_name3;@mod_name4;@mod_name5

*NOTE* When launching your game with the Steam Launch Parameters, any mods enabled via this method will activate every time you launch Arma 3 unless you remove/change the entry in the "Set Launch Options" dialogue. If you change mods frequently, it is recommended you use a launcher.

If the above information still does not provide you with enough to learn how to install custom addons and mods you can always ask in our Guide On Installing Mods thread.
