A "beta of the beta" is already available online in form of the development build of the Alpha for those that have it. This stage adds attack helicopters and a 3rd faction (Greek army). It also adds the Ghosthawk of bin Laden fame. Main battle tanks, fighter jets and a map 20x bigger than the Alpha's won't be available until the final game is released.

Today Bohemia Interactive confirmed the 25th of June as the official release date for the Arma 3 Beta. Building upon the well-received Arma 3 Alpha, the Arma 3 Beta features a varied selection of brand new content – including 10 vehicles, 7 weapons, 4 showcase missions (Combined Arms, Supports, Commanding & Night), 2 multiplayer scenarios and 4 challenges.
Set against the beautiful backdrop of Stratis (20 km²), the Arma 3 Beta turns its focus towards firepower and logistics. The Challenges game mode will also be making its first appearance, enabling players to practice their weapons handling and movement across a selection of firing drills. Plus, all of the content from the Arma 3 Alpha will be available, alongside the popular scenario editor and modding support.
People who are currently participating in the Arma 3 Alpha will gain access to the Arma 3 Beta through an automatic Steam update. Those who are new to Arma 3 can join in by purchasing the Arma 3 Beta (which includes a version of the full game) from Steam or Store.bistudio.com.
The price of the Arma 3 Beta, in comparison to the Arma 3 Alpha, will be increased. The regular Arma 3 Beta will be available for 34.99 EUR/29.99 GBP/44.99 USD (current price: 24.99 EUR/19.99 GBP/32.99 USD), while the Arma 3 Digital Deluxe Edition will be sold for 44.99 EUR/39.99 GBP/59.99 USD (current price: 39.99 EUR/34.99 GBP/49.99 USD). Please note that the current (heavily discounted) Alpha deal, which includes Beta-access and the full game, will still be available until Tuesday June 25th.
