Warner Bros. Interactive is proud to announce a new downloadable multiplayer online battle arena game, Guardians of Middle-earth.

The game comes with more than 20 characters and supports five-on-five battles.

As you can guess, the playable guardians include Gandalf, Sauron, Gollum and Thráin, and Warner says that players can expect tie-ins to Peter Jackson's new film The Hobbit: An Unexpected Journey.

The game will be released this fall on Xbox Live Arcade and Playstation Network. Expect more details at the E3.
