Warner Bros. Interactive Entertainment today released another new trailer for Middle-earth: Shadow of War, spotlighting the Dark tribe, a group of Orcs who utilize stealth and assassination to dominate Mordor on behalf of the Lord of Mordor, whom they have a fanatical reverence for. In Shadow of War, Orcs now belong to tribes, which extend their influence stemming from the Overlords ruling the mighty fortresses throughout the open world, providing a rich ecosystem of missions, exploration and a dynamic Orc society with diverse Orc cultures, all brought to life through the expanded Nemesis System. Adept at ambushes, double-crosses and battlefield trickery, the Dark tribe wields power beyond what their numbers would suggest, favoring treachery and betrayal to get the job done.
