Want to take a tour, albeit a sometimes bloody tour, down memory lane in Tolkien’s ultimate tale of good versus evil? Here are 10 key places in the game that you may remember from the books.

HELM’S DEEP

You start out defending the Deeping Wall and the good men of Rohan, and end in a battle to save Théoden in his throne room. When the Orcs crush forward against the stone ramparts in Helm’s Deep, you will really feel the press of Sauron’s horde and the delicate balance of despair and salvation that hangs over all of Middle-earth.

ISENGARD

Saruman’s Orcs have ravaged the land, and Wormtongue is a far greater threat than you ever imagined, able to slink into the shadows and slay with more than cruel words. You will gain the aid of Ents here (and play one yourself!) as you smash through to the Tower of Orthanc and play Gandalf against Saruman.

MINES OF MORIA

The dark twists and deadly drops of Moria are far from its greatest perils. The place teems with Orc stink, and the rumble of Trolls in the depths shake even the stoutest Warriors. Should you make it to the final chamber, the direst evil stands in your path—the mighty Balrog!

OSGILIATH

In the dying ruins of Osgiliath, you seek out the aid of Faramir and his Rangers (or slay him when playing through on the side of Sauron). Cut through Orc after Orc as you shepherd the Hobbit, Frodo Baggins, to safety outside the city.

MINAS TIRITH

The greatest city of the West, Minas Tirith, is falling. Join forces with Gandalf to save it against all odds on your first pass through as a good guy, then become a member of Saruman’s team as you dismantle it stone by stone on your second pass under Sauron’s guidance.

PELENNOR FIELDS

Huge siege engines and gigantic Oliphaunts crush the defenders as they crunch toward Théoden’s war camps. Legolas and Éowyn come to you aid, but will they be enough against hundreds of Orcs, Easterling armies, war machines and the Lord of the Nazgûl?

THE BLACK GATE

Aragorn, Gandalf, Gimli and Legolas lead an army into Mordor’s fearsome fortress. You can play all four Heroes as you throw back Orcs, burn Trolls, and duel with the Mouth of Sauron and his deadly Captains. Can you outlast the endless horde long enough for Frodo to destroy the One Ring in Mount Doom?

MOUNT DOOM

You must kill the thieving Hobbit, Frodo Baggins! Yes, once you’ve unlocked the good side, you can play through the evil side as a lieutenant of Sauron. In the fiery caverns of Mount Doom, you race around as the Nazgûl and the Witch-king, cutting through traitorous Orcs who want the One Ring for themselves, in order to stop the Hobbit from destroying the Master’s precious artifact.

WEATHERTOP

The forces of Sauron are on the move. In a massive battle around Weathertop, you play one of the Orc classes (and later Saruman) accomplishing multiple mission objectives. In the end, you must face the imposter king Aragorn atop the rocky precipice.

RIVENDELL

Elrond and the Elves defend their home from your ruthless Orc army. Smash through the Elven swords with your mighty Trolls and powerful Orc classes, and square off against Elrond in a battle to the death. When Legolas joins the Elves, you gain the ultimate ally—the Dark Lord Sauron!
