Addons

Addons are content additions to the game engine. Addons can take many forms such as weapons, buildings, vehicles to name a few, are developed and released by members of the Bohemia Interactive community or by Bohemia Interactive themselves.

An addon is an archive (pbo) of files that the game loads at startup. Generally when most people think of addons, they immediately think of a new unit, or a new terrain, but in some cases an addon can contain only a config.cpp file and a few scripts, or some images.

Installation

There comes a time when you've downloaded so many addons from the Internet and plunked them in your ~\addons folder, that eventually, can cause a clash between one addon and another. What Bohemia Interactive has done is introducing mod folders to separate addons into different folders. The mod folders is the method that should be used when testing out new addons.

Always review the included ReadMe file for further information about the installation of an addon.

Arma 3

• Addons
  must be installed into a custom modfolder. It is not recommended to place addons into the original Addons folder. Mods can also be installed from the Steam Workshop.

Steam Workshop

Arma 3 has introduced a new way of publishing, browsing and installing mods: Steam Workshop. There are two main parts to using Workshop: Publisher to publish addons into Steam Cloud and Arma 3: Launcher to download and/or update mods and launch the game with a selected set.

A typical use for mods case is:

• Creator publishes file to Steam Workshop using Publisher. He adds a tag mod to the published file.
• User browses Steam Workshop and subscribes to content he likes.
• Arma 3: Launcher downloads and updates the subscribed mods (it only shows files with a steam tag mod).
• User can select which mods to load into the game.

A typical use for scenarios is:

• Creator publishes a scenario from in-game editor. Editor auto-adds the tag scenarios.
• User browses Steam Workshop and subscribes to content he likes.
• Steam downloads and updates the subscribed scenarios. They are accessible in-game from Play/Scenarios/Steam subscribed content (only content with a tag scenario is displayed here).

Arma 2

• Addons
  must be installed into a custom modfolder. It is not recommended to place addons into the original Addons folder.

• Custom Campaigns
