'Stones Unturned', Mafia III's second of three DLC expansions is available now, telling the story of how Lincoln Clay and CIA agent John Donovan came to forge a brotherhood on the battlefields of Vietnam. In the main game, Donovan becomes an instrumental part in helping Clay exact revenge upon those who wronged him. In Stones Unturned, Clay will return the favour for Donovan when he's betrayed by a man named Connor Aldridge who left him for dead. Back on the scene in New Bordeaux, Aldridge is on a violent rampage searching for "highly volatile" lost cargo. It'll be down to Clay and Donovan to stop him. Together, they'll fight Aldridge's highly-trained mercenary army, using heavy weapons, turreted vehicles, sniper support and other "unique rewards". Mafia III's Stones Unturned DLC is out now, available standalone or with the Season Pass. A third and final DLC will be coming soon. Source: Xbox Achievements
