Description:
Latest public beta patches are available from http://www.arma2.com/beta-patch.php including change logs.

Please note: Arma2 OA Beta is a public preview release intended for developer testing and community feedback. It may be updated often and we use them to verify that a bug we are tracking has been fixed. We make the beta builds for testing only and also to allow developers in the community to test their content with the upcoming versions before they are released as the official release. We write code and post the results frequently so people like you can join our testing process and report bugs but Arma2 OA Beta might crash on startup or cause any other kind of unpredicted problems so please do not bother downloading Arma2 OA beta builds if you're unwilling to put up with problems or help with the testing of the game and stick with the latest official release instead.

How to stay up to date with the latest beta:

• MadDogX made a ARMA 2 Beta Notifications website.
  
It also comes with an RSS feed. Twitter functionality is in the pipeline aswell.

• kicktd made an Arma 2/Arma 2 OA/CO Beta Patch Downloader. This program will check to see if a new patch is available and if the patch is not in the downloads folder (same folder as the program) it will download the patch. This will not install the patch to prevent unwanted installation.
  
• danczer made an Arma 2 Beta List Application to follow new beta patch releases. The current version is 1.15.
  
It offers some additional features which are handy when you want to follow the beta development.
You can find more info and download the application from here: Arma 2 Beta List Application.

• Yapab made an email notifier, fill in the form and make sure to allow the email to come through so it does not end up in your spam box!

Multiplayer:
Usually, beta versions will be compatible in multiplayer with either previous or the upcoming public final release (unlike in Arma 1 where beta versions were causing large incompatibility in the multiplayer community).


System Requirements:
- ANY ORIGINAL VERSION OF ARMA2 Operation Arrowhead from 1.57 (including Steam version)
- DirectX 9 March 2009 is required


Installation:
Run the patch exe to apply the patch setup automatically (you may be prompted to choose your exact version in some occasions).
* It will install all beta content to a mod folder "Expansion\Beta", including the beta exe (that has to be run properly with working directory set to the main game installation, see below for more information)
* To launch Arma2 Operation Arrowhead beta patch you need to go to the main game directory and click on shortcut "Launch Arma2 OA Beta Patch"
* You can configure your Arma2 OA with Beta Patch including other mods etc., just make make sure that in your ArmA Shortcut start-up Target line;
- You are running the Arma2OA.exe from your "Expansion\beta" folder.
- You have "Expansion\beta;Expansion\beta\Expansion" in your modfolder as in -mod=Expansion\beta;Expansion\beta\Expansion
example: "C:\Program Files\Bohemia Interactive\ARMA 2 Operation Arrowhead\Expansion\beta\armaOA2.exe" -mod=Expansion\beta;Expansion\beta\Expansion
- Make sure the shortcut's "Start In" section refers to main "ARMA 2 Operation Arrowhead" main working folder and NOT "ARMA 2 Operation Arrowhead/beta", example:
"C:\Program Files\Bohemia Interactive\ARMA 2 Operation Arrowhead"

You can always run your Arma2 OA final version in the main Arma2 OA folder if you use default application shortcuts, start menu or run the regular arma2OA.exe without the beta mod folder.
