World of Warcraft celebrates its seventh birthday on Nov. 23, and in observance, anyone logging in between Sunday and Saturday, Dec. 3 will get a free celebration item that temporarily grants an XP boost.
The "Feat of Strength" and the celebration item also grant a special tabard and a reputation bonus, in addition to shooting off fireworks, in-game. So be prepared for a lot of pyrotechnics.
Further, World of Warcraft will air a new celebrity-voiced advertisement for the holidays. It debuts Sunday on CBS' NFL broadcast of the San Diego-Chicago game. Kickoff is 4:15 EST.
