ArmA III is an upcoming military-simulation video game developed and published by Bohemia Interactive Studio (BIS) exclusively for the PC. It is the third installment of the ArmA series, officially announced on May 19, 2011, and is built around the new Real Virtuality 4 engine owned by BIS. Release date for the game is to be announced during 2013. The playable alpha version of the game was made purchasable on the Steam store and BIS' page on March 5, 2013.
The storyline is set in mid-2030s during an international conflict between NATO and the Iranian Armed Forces in the Aegean Sea. The main protagonist is Captain Scott Miller, a former United Kingdom Special Forces (UKSF) operator who becomes stranded on a 350km² fictional Mediterranean island called "Altis" (Based upon the 475km² Greek island, Lemnos), and must fight his way out by building an effective resistance force in the process and cooperate with the local population.
Traditionally with the ArmA series, the player will also be able to play with three more characters: Lieutenant Jeff Larkin, a helicopter pilot; Sergeant Rick Hutchinson, a (possibly) tank commander; and Corporal Ben Kerry, a light infantry soldier - all are serving in different units of the United States Army 7th Infantry Division (7th US Army Europe).
