Back in 2007: the legendary Wrath of the Lich King add-on for the classic version of World of Warcraft was released

The Wrath of the Lich King expansion has been released on the servers of the classic version of World of Warcraft, which most fans of the game consider the best addon.

In this addon, players will go to the distant continent of Northrend, to give battle to the powerful Lion King and his army of the undead.

Heroes of the Alliance and Horde will have access to many new features, skills, game locations, dungeons, raids, and other activities.
To get access to WoW Classic, all you need to do is pay a subscription to the current version of World of Warcraft.
