This "Gold" package edition of Bohemia Interactive's ArmA includes both the original Combat Operations game and its expansion pack, Queen's Gambit (which was also made available as a retail download for players who already won the original game). The squad-based shooter offers a story-driven single-player campaign, as well as an online multiplayer mode that connects up to 50 'net-enabled combatants in virtual battlefields than may span 150 square miles or more. Queen's Gambit adds new single-player missions, featuring new characters, vehicles and seven new campaigns. ~ All Game Guide
