Middle Earth: Shadow of Mordor will be getting a Season Pass for its DLC. Warner Bros detailed some of the content that will be included today, promising more in the future as well.
The Season Pass will include a "Guardians of the Flaming Eye" warband mission, two story missions called Lord of the Hunt and The Bright Lord, and early access to the Trials of War challenges. More content like runes and skins, as well as "future add-on content," is promised as well. WB didn't detail the price for the package, but it's a safe bet it will save a few bucks from buying the pieces individually.
This is in addition to the various retailer exclusive bonuses already announced. Shadow of Mordor will hit on September 30 on consoles, and October 2 on PC.
