Following in the tradition of previous Blizzard expansion sets, Warcraft III: The Frozen Throne provides gamers with a vast new chapter in the epic Warcraft saga.

In the single-player campaign, players revisit the war-torn world of Azeroth. Several months have passed since Archimonde and the Burning Legion were defeated at the battle of Mount Hyjal, yet a new threat has arisen throughout the land.

The evil Lich King Ner'zhul has been imprisoned inside the Icecrown glacier, deep within the arctic continent of Northrend. Although the former Orc Shaman lacks physical form, his soul lives on, forever seeking a means to escape his icy prison. As the saga continues, it is revealed that both the Night Elf renegade, Illidan, and the traitorous Death Knight, Arthas, find the Icecrown glacier and discover whatever powers it may hold inside.

While it is uncertain as to what is being sought inside the icy tomb, players must traverse uncharted lands and battle treacherous new enemies to uncover the schemes of these nefarious beings, and save all of Azeroth from the forces of darkness.
