World of Warcraft expansions are major updates that introduce new content, features, and gameplay mechanics to the game. Each expansion typically raises the level cap, adds new zones, dungeons, and raids, and often introduces new playable races and classes. These expansions enhance the overall experience and keep the game fresh for players. Since its launch in 2004, World of Warcraft has released several expansions, including The Burning Crusade, Wrath of the Lich King, and Shadowlands. Each expansion builds on the game's lore and offers players new challenges and adventures in the ever-evolving world of Azeroth.
