Ubisoft announces Silent Hunter Online, an upcoming free-to-play, browser-based multiplayer game inspired by the Silent Hunter submarine simulation series. The Silent Hunter Online Website is online, offering a promotional trailer and sign-ups to be a beta tester. Here's a bit on the game:

Developed by Ubisoft Blue Byte®, the renowned studio behind popular PC game series such as The Settlers® and Anno, in collaboration with Sproing, Silent Hunter Online promises players a realistic, constantly evolving submarine simulation unlike any other. The game takes full advantage of Adobe Flash® Player 11 technology to bring stunning 3D graphics to browsers.

Silent Hunter Online sees the return of the large array of historically accurate submarines that made the franchise famous, and invites players to experience them online in new ways. At the heart of the game is “the Battle of the Atlantic”, an innovative dynamic campaign in which individual successes impact all other players through asynchronous gameplay. Also, for the first time in the Silent Hunter series, players will be able to play every mission of the campaign in co-op.
