One of World of Warcraft: Wrath of the Lich King Classic's most iconic quests is not working as intended, with Blizzard advising players to steer clear until the issues are resolved.

The quest in question is the Battle for the Undercity. Following the events of the game's pivotal Wrathgate cinematic, players of both the Horde and the Alliance are tasked with invading the Undercity and finding those responsible for the tragedy. It's an incredibly unique event and quest with some lucrative rewards, and one that was only playable for a relatively brief period of time originally. Added in 2008 with the release of Wrath of the Lich King, the quest was removed roughly two years later in November 2010's patch 4.0.3, just ahead of the game's Cataclysm expansion. The 2022 re-release of the beloved expansion then serves as a great way to revisit the quest, or for many players, experience it for the first time.

Unfortunately, it doesn't sound like the issues plaguing Wrath Classic's Battle for the Undercity quest event will be fixed anytime soon. Blizzard says due to the "extreme complexity" of the event, a fix is "unlikely" to arrive in the next few days. In the meantime, Blizzard is implementing a way to skip the event, with the hope of adding a way for players to go back and try again at a later date.
