Game description from the publisher:
The Hobbit: An Unexpected Journey is an exciting all-new co-operative game of adventure in which you join Bilbo Baggins and his thirteen Dwarven companions on their journey through the Lonelands and Misty Mountains, encountering Goblins, Trolls, and other dangers that seek to put an end to their adventures. Traverse your way through two boards, each more difficult than the last, with the goal of coming out alive and prepared for the dangers that lie ahead. Your accumulated points at the end of the game will be your team's mark for finding out how good of a Company you really are!
The Hobbit: The Desolation of Smaug , although it is also a stand-alone game, can be used as an expansion to this game.
