Īrma 3 was conceived around 2010 as a science fiction spin-off of the Arma series, but gradually became a grounded mainline entry. Arma 3's plot is progressed through multiple episodic singleplayer and co-op campaigns, most of which follow different perspectives surrounding the 2035 'Altis Incident', a war fought in Altis and Stratis involving various factions, the most major belligerents being the United States-led NATO and the Iran- and China-led Canton Protocol Strategic Alliance Treaty (CSAT).
The game's maps feature photorealistic terrain and water environments.
The game's expansions are set on the South Pacific archipelago of Tanoa the Strait of Gibraltar island of Malden the Eastern European country of Livonia the Western Saharan country of Argana and several real-life locations, including parts of Mainland Southeast Asia and Europe. Īrma 3 primarily takes place in the mid-2030s, on the fictional islands of Altis and Stratis in the South Mediterranean Sea. Arma 3 was released for Microsoft Windows on September 12, 2013, and for macOS and Linux on August 31, 2015. It is the third main entry in the Arma series, and the eighth installment in the series overall. Arma 3 is an open world tactical shooter simulation video game developed and published by Bohemia Interactive exclusively through the Steam distribution platform.
