Arma 3 is a combined arms military game set in a massive military sandbox. The game features the islands of Altis (270 km²), Stratis (20 km²), and Malden (62 km²), a singleplayer campaign, showcase missions, firing drill challenges, multiplayer scenarios, more than 20 vehicles and 40 weapons, a powerful scenario editor with Steam Workshop integration, and modding support. The key features are also listed here. If you are new to Arma 3, the best place to start is Arma 3 Bootcamp (available under ‘Learn’ in the in-game main menu). We also recommend you to check out the official Community Guide video series, which covers some of the basics in Arma 3.

We will communicate large new updates on our social channels [Facebook, Twitter], via Steam announcements and on All updates will automatically download and install via Steam.

We have set up a dedicated Feedback Tracker where you can report errors and game bugs. Our forums are designed for reaching out to other players. Also, be sure to keep track of our Dev Hub page for all the latest development intel.

If you follow the Arma 3 Dev Hub, you will see that some posts are targeted at ‘Dev-Branch’ users. What is Arma 3’s Dev-Branch?

The Development Build is an experimental and largely untested version that contains data directly from individual team members as they work. Sometimes a part of this version can be completely broken. Do not use this branch unless you would like to participate testing or are otherwise interested in it. Also, in case you use a limited bandwidth Internet connection, please be aware that this branch can be frequently updated with hundreds of megabytes. We thank those who do and who have helped us catch errors ahead of big releases.

If you're interested in our Dev-Branch build, you can opt in via the Steam client. Right-click Arma 3 > Properties > BETAS tab > select Development Build from the drop-down (no access code needed) > let the game update.

Check out the Dev-Branch changelog on the forums, and discuss the version here. Reporting issues is preferred via our Feedback Tracker.

Main branch updates are the culmination of 'Dev-Branch' versions, community testing and internal QA. It is the recommended version for most players.

There’s no demo available for Arma 3.

Yes, the same guidelines apply as to our other games with regards to copyrights.

For a standard (listen) server, go to the Multiplayer menu. Select New to create a new server on either LAN or the Internet. Select the desired scenario and server parameters and confirm. Arma 3 also supports Dedicated Servers for greater performance. Visit the Community Wiki for details.

This depends on the scenario that is selected. While there are no technical hard-limits, reasonable maximum player counts depend on the server hardware and available bandwidth. Typical scenarios cater from 2 to 64 players.

For greater protection from cheaters, consider finding servers that use the integrated BattlEye anti-cheat engine. Server administrators have control over various anti-cheat measures. Use the server browser filter to find these servers.

This may be caused by several things. You may be running a different game version (e.g. servers on the experimental development branch), or servers may require the use of certain (user-generated) add-ons and mods. Finally, there may be connection problems between you and the server due to firewalls or other obstacles along the way.

Try to configure your in-game video options to match your hardware setup (use auto-detect as a basis). It is also recommended to install the latest graphics hardware drivers for your graphics card(s). Should you not be using SSD storage devices, consider defragmenting your drive(s). Finally, use the Steam client to verify the game data integrity automatically.

Please take a look at this page with a description of common error codes and proposed solutions.

Steam Workshop is a functionality on Steam which enables you to play and share user-created Arma 3 scenarios and addons with the entire Steam Community.

Arma 3 Units is an official website that provides an online catalog of existing Arma 3 community groups/clans. You can use it to find units to play with – or, if you're already running a unit, to recruit new members.

You can download the manual here. It is also located as a PDF in the Arma 3 installation folder on your PC (language depends on the language selected in your Steam client).
