Warner Bros. has announced a slate of DLC for Middle-earth: Shadow of War. The publisher detailed the additional content in a new trailer, which provides a look at the new tribes and story campaigns players can experience soon.

Developer Monolith will add four expansions to the game, two of which come in the form of new tribes. First is the Slaughter tribe, a "gruesome" tribe of Orcs that are "capable of ambushing players at any point." The expansion will launch this November and introduces new missions, a new fortress with an Overlord throne room, monuments, outposts, and new Epic and Legendary Orcs.
