Blizzard will be giving away a free in-game item to World of Warcraft players in celebrations of the game's seventh birthday on November 23.
"It's been a truly incredible seven years, and we'd like to thank you all for joining us for yet another fantastic year," said the developer via its official blog.
"To celebrate, players who log into the game between November 20 and December 3 will earn a feat of strength added to their Achievements and a 'Celebration Package' item. Using your item will get the celebrations rolling by shooting off fireworks*, applying a (visual only) tabard to your character, and granting a 7% bonus to experience and reputation gains while active."
World of Warcraft: Cataclysm was crowned the Golden Joystick 2011 MMO of the Year last month. Released on December 7 2010, Cataclysm introduced thousands of new quests, new lands to explore and extensively revamped the world (of Warcraft), making it one of Blizzard's most ambitious expansions yet.
