Next month, PC Battle for Middle-earth II expansion Rise of the Witch-king will be hoisting its RTS banner in your local games emporium. A new single-player campaign and new faction are waiting to be unpacked, and the expansion additionally heralds the arrival of new units for the game's existing factions - it's these units that are the focus of a new Witch-king video diary viewable on this here page.

In the video diary, producer Amir Rahimi, chats about the impact of the voice of the community on the new units for existing factions and a new unit type called the 'mini hero horde' that's being introduced. Rahimi explains that the goal behind creating the new unit type "was to enhance certain faction strategies". Plus, he talks about new heroes and new regular units that have also been added to existing factions. Naturally, the diary features gameplay footage focussing the new additions being discussed.
