Blizzard has announced that the World of Warcraft: Burning Crusade Classic will be available in June.
Players – new and old alike – will have the opportunity to return to Outland when World of Warcraft: Burning Crusade Classic is released on June 1st.
Starting May 18, after each scheduled regional maintenance, a Patch will be released before expansion, and each character must choose to advance to the Burning Crusade, move to the Classic Era, or use the Character Clone service to play in both games. More about it here.
The Burning Crusade, originally released in January 2007, takes players to Outland to stop the Burning Legion.
When it came out, the expansion brought with it the Blood Elf for the Horde and Draenei for the Alliance, so you will soon be able to use these races again.
If you just jump into WoW, Burning Crusade has also brought the Arena PvP system, the Jewelcrafting profession, flying horses and Aldor and Scryers of Shattrath.
As with WoW Classic, anyone who subscribes to World of Warcraft can also play Burning Crusade Classic at no additional cost.
