UPDATE 2.05pm: After this morning's leak, publisher Warner Bros. has now made Middle-earth: Shadow of War official.
The sequel will let you wield a new ring of power and fight both Sauron and the winged Nazgul, via another huge open-world, improvements to the original's impressive Nemesis System and a story which adapts to your decisions.
Best of all? It's out in the UK on 25th August (or 22nd August in North America).
PC, PlayStation 4 and Xbox One editions of the game will arrive then, with support for Xbox One Scorpio when it arrives.
Here's the first trailer:
ORIGINAL STORY 9.05am: Middle-earth: Shadow of War is yet to be officially announced, but we now know a lot more about the game thanks to a leak from US shop Target.
The much-rumoured sequel to Shadow of Mordor will once again let you conquer land and take down enemies using the original's acclaimed Nemesis system.
This time, however, you're looking to forge a new ring of power, similar to Sauron's.
Target's product listings have now been pulled, but not before they were pasted onto NeoGAF:
"Experience an epic open-world brought to life by the award-winning Nemesis System. Forge a new Ring of Power, conquer Fortresses in massive battles and dominate Mordor with your personal Orc army in Middle-earth: Shadow of War.
Go behind enemy lines to forge your army, conquer Fortresses and dominate Mordor from within. 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.
Sounds good to us.
Shadow of War will also be available in a Gold Edition with access to four expansions: Slaughter Tribe Nemesis Expansion, Outlaw Tribe Nemesis Expansion, The Blade of Galadriel Story Expansion and The Desolation of Mordor Story Expansion.
Together with a "Gold War Chest", these packs represent "over $125 in total value".
The two Nemesis Expansions will each let you take on a new Orc Tribe, with new missions and gear. The two Story Expansions include a new campaign and playable character - interesting.
Warner Bros. has yet to respond to the leak - but it likely won't be long until the game is fully unveiled.
