Last month, while Tim was still reeling from his Mozû the Blight encounters, WB Games detailed the Middle-earth: Shadow of War Expansion Pass and its four incoming portions of premium DLC. Two of these now have launch dates, and the action role-player is also in-line for four complimentary updates before year's end.   

Endless Siege is a fortress-defending scenarios that pits players against Sauron's forces amid the Endless Siege, while Rebellion has you taking rebel Ologs and Uruks to task. Moreover, Enhanced Photo Mode lets you "capture every battle and siege and apply new filters, frames and textures", whereas Online Fight Pits has you challenging other players' Orcs followers in a gladiator-style duel to the death. A new 'Brutal' difficulty ups the stakes—more challenging than Nemesis, "with no last chances."
