Guild Wars 2 has launched and is already breaking records, NCsoft and ArenaNet have announced.

Prior to launch more than one million fans pre-purchased the game to ensure access to the three day Headstart weekend. So high was demand for the title that over this three day period that a record-breaking 400,000 concurrent players were registered online.

"This is the culmination of a five-year journey and to be greeted by this level of enthusiasm by our fans is truly amazing," said O'Brien, president and co-founder of ArenaNet. "But really our work is just beginning. Now our focus is shifting to building on this living world we've delivered, continuously refining our game and improving services to ensure our players have the best possible experience."
