ARMA III is a massively multiplayer FPS with a dedicated campaign mode. Set in the 2030s, the battlefield follows military warfare in the Greek islands between NATO forces and CSAT (Canton-Protocol Strategic Alliance Treaty) led by a resurgent Iran with a coalition of other Middle Eastern and Asian nations. 

Captain Scott Miller from British Special Forces leads the battle and it is a fight for survival when the defensive NATO operations fail. Miller will have to successfully complete a series of missions, right from controlling heavy armored vehicle battles to solo infiltration assignments. Experience true military warfare on a vast island terrain and take down enemies using an array of customizable weapons including assault rifles, rocket launchers and sniper rifles.
