We've known for some time that a sequel to Middle-earth: Shadow of Mordor was likely in the works, and today new details regarding the follow-up were leaked.

Revealed in a listing on Target's international website (as discovered by NeoGAF member DeathByBacklog), the new game is called Middle-earth: Shadow of War. The page features box art for it and a brief description.

"Go behind enemy lines to forge your army, conquer Fortresses, and dominate Mordor from within," it reads. "Experience how the award-winning Nemesis System creates unique personal stories with every enemy and follower, and confront the full power of the Dark Lord Sauron and his Ringwraiths in this epic new story of Middle-earth."

PS4 and Xbox One versions are both listed. The original Shadow of Mordor was also available on PC, though the absence of a PC version on Target's website doesn't preclude it from also being in development.

A release date is stated as August 22. That might prove to be true, but early release dates on retailers' websites don't always pan out.

In addition to the standard version of the game, a Gold Edition will also apparently be available. Here's what that includes, based on the description:

Slaughter Tribe Nemesis Expansion

Outlaw Tribe Nemesis Expansion

The Blade of Galadriel Story Expansion

The Desolation of Mordor Story Expansion

Gold War Chest

Over $125 in total value

The two Nemesis expansions feature "a new Orc Tribe featuring new enemies, followers, missions, abilities, weapons, Fortress, and wilderness updates, and a Mythic Gear Set." The story expansions, meanwhile, have "a new campaign, playable character, and abilities, side missions, enemies, allies, and more."

The Gold Edition page also reveals slightly more about the game itself, teasing the ability to "[f]orge a new Ring of Power, conquer Fortresses in massive battles, and dominate Mordor with your personal Orc army."

We'll have more on Shadow of War as it's announced.
