The second expansion pack for the fantasy role-playing online game the World of Warcraft has gone on sale.
More than 2,000 people waited outside an Oxford Street store in central London, in advance of a special midnight opening.
Similar launch events are being held in North America, Taiwan, and South Korea.
The Wrath of the Lich King includes a bonus continent for high-level players, a plethora of new enemies, extra equipment, spells, and new professions.
We've been looking forward to this launch event all year

The expansion also gives players the chance to take on a new type of character known as a Death Knight.
On the stroke of midnight, players - many of whom had queued for hours - got to pick up a copy of the game signed by the developers.
