If you own Middle-earth: Shadow of Mordor, perhaps you noticed a recent update. Along with the usual bug fixes, this update adds support for the new Lord of the Hunt DLC, which is available today.
The Lord of the Hunt DLC was previously detailed at the end of October. A new story will see Talion team up with Torvin the Dwarven Hunter to tame all-new monster additions, like the Wretched Graug and the Caragath, and take the fight to Sauron. New Beastmaster Warchiefs will also debut, with the ability to engage in mounted combat. Other additions include new Runes, trophies, Beast Hunting challenges, and a Lord of the Hunt character skin for Talion.
The Steam Announcements page notes that the new Lord of the Hunt DLC will require slightly higher specs, so keep that in mind if you're picking this up on PC. The Lord of the Hunt DLC is available now on PC, Xbox One, and PlayStation 4 as part of the game's Season Pass. For more on the add-on content, check out the new trailer.
