Ubisoft announces Tom Clancy's Ghost Recon Online, an upcoming free-to-play third-person multiplayer shooter based on the tactical shooter series. The game is in development at Ubisoft Singapore, and while it doesn't carry a release date at this time, closed beta testing is set to begin this summer, and those interested in the beta can sign up on the game's official website. Word is: "With Ghost Recon Online, Ubisoft is delivering the most social, connected and customizable Ghost Recon experience yet. The game offers players the ability to choose between three different classes of Ghost, customize their weapons, deploy cutting-edge military technology, and share intel with their team. Ghost Recon Online also features a rich lobby platform for hosting social and persistent progression features. Ubisoft also will back the game with a full set of services, including regular events and game content updates, customized content based on community feedback, and live support."
