Turbine has announced the release date for its upcoming LotRO digital expansion, Siege of Mirkwood, and the accompanying Adventure Pack.Siege of Mirkwood, which is released on 1 December, introduces several new features to the game. Players will be able to use the new Skirmish system, which allows up to 12 adventurers to join up and take on a randomised instance. Soldiers that can be trained and customised can also fight alongside players with this new feature. Skirmishes can be joined from anywhere in-game, and characters will instantly travel directly there to take part.The expansion also offers hundreds of new quests in and around the new region of Mirkwood, which is home to the menacing fortress of Dol Guldur. The fortress contains the new 3-man instances, the Dungeons of Dol Guldur, the Sword-halls, and the Warg-Pens. The 6-man instance calls players to tackle the Sorcerer of Dol Guldur himself, and finally the 12-man raid where players face the Nazgûl Lord, Lieutenant of Dol Guldur.Other new features include a revamped mount system, allowing players to use emotes, certain skills and interact with NPCs while mounted. A shared storage system is also being introduced, permitting players to swap items between characters.
