Eurogamer has taken a closer look at Ulduar, which Blizzard has coined as "World of Warcraft's most ambitious raid to date."
Eurogamer has it on good authority that Ulduar's size will surpass that of the Sunwell, the climactic raid of the game's Burning Crusade era.
Beyond the gates to Ulduar in the Storm Peaks region, players will find "a horror even the Titans could not, would not destroy, an evil they merely... Contained. Beneath ancient Ulduar, the Old God of death lies, whispering.... Tread carefully, or his prison will become your tomb."
Ulduar will be composed of two distinct areas. The first is an "epic battle against a vast army standing between you and the entrance of the dungeon proper". You'll be able to face this Iron Army down and defeat the Flame Leviathan tank using motorcycles, demolishers and siege engines.
Of the dungeon's 14 bosses, 11 will have Hard Modes - optional ways to adjust the difficulty of the encounter and improve the loot, similar to the current Sartharion raid in Wrath of the Lich King.
"Ulduar isn't the first dungeon to include Hard Mode, but it certainly makes the most use of it. Out of 14 bosses, 11 will have a Hard Mode that offers additional challenges and rewards," said Blizzard.
