Activision and id Software have released the final "unlockable" map for Return to Castle Wolfenstein: Tides of War, available via Xbox Live! The map can be played in the game's Stopwatch and Elimination multiplayer modes, and word is: "In this new map, Allied players must infiltrate a German occupied Chateau being used as a Nazi base of operations, locate secret documents, and transmit them back to U.S. headquarters while in the midst of combat. In order to succeed, the Allied team must act with brute force and destroy the outer perimeter doors to gain access into the Chateau library, located deep within the German stronghold."
