Armed Assault 3 (stylized as ArmA 3) is an open world tactical shooter video game developed by Bohemia Interactive. The Alpha was relased on the 5th of March and the full game is expected to be released in the third quarter of 2013. The game takes place in near future during Operation Magnitude, an operation launched by NATO forces fighting "Eastern armies" in Europe. Mostly around Greece.
ArmA 3 is set in the mid-2030s, where NATO forces deployed in the Greek islands of the Aegean Sea - including elements of the United States Army's reactivated 7th Infantry Division - are trying to hold off a massive Iranian military offensive from the east. During the singleplayer campaign, the player will take the role of British Special Forcessoldier, Captain Scott Miller. Initially the player must survive on their own after friendly forces are defeated in a failed NATO operation. During the campaign the player will face everything from lone wolf infiltration missions, to the commanding of large scale armored operations. The player will be able to choose different objectives and weaponry (like UAVs, artillery, and air support) according to their play style. 
ArmA 3 takes place on the Aegean islands of Altis and Stratis of Greece, in the Mediterranean Sea. They will feature photo-realistic terrain and water environments. Altis will be the largest official terrain in the Arma series with ground area covering 270 km². The smaller island, Stratis will expand over area of 20 km². The islands will feature over 50 villages with buildings that are both enterable and destroyable.
