ARMA II -- The 27th U.S. Marine Expeditionary Unit has been deployed to the former soviet republic of Chernarus: a small country chained to the threat of an upcoming civil war. Force Reconnaissance Team "Razor" is among the first to fight. This elite five-man team is about to fall down the rabbit hole, trapped in a war not only for control of the country, but also the hearts and minds of its people. Arma II is based on the latest generation technology, offering large –scale game world, authentic and extremely detailed modern units, weapons, vehicles and environments, challenging single player and vast array of multiplayer options.
OPERATION ARROWHEAD -- The action resumes three years after the conflict in Chernarus, portrayed in the original Arma 2. A new flashpoint in the Green Sea region heats up and coalition forces led by the US Army are sent to Takistan to quickly restore peace and prevent further civilian casualties. In Arma 2: Operation Arrowhead’s all-new single-player and multiplayer campaigns, players will experience new large-scale maps, and new simulation features that include new radio chatter and languages, controllable Unmanned Aerial Vehicles, thermal imaging, decoy flares and smoke screen cover. Additionally, owners of the original Arma 2 will now be able to utilize Arma 2: Operation Arrowhead's new weaponry, vehicles and factions in the multiplayer mode of Arma 2, breathing new life into the battle.
