Guild Wars 2 shifts 2 million units

ArenaNet has announced over 2 million copies of Guild Wars 2 have been sold worldwide.

The subscription-free MMO launched last month after many years of development.

ArenaNet president and co-founder, Mike O'Brien, said: "Reactions from around the world justified the time and care we put into developing Guild Wars 2 and making it into the game it is today.

"And this is only the beginning. We're continually fine-tuning the game to deliver the polished experience that our players expect, and we're already working on new adventures and experiences to introduce into this truly dynamic online world."

Fan demand has been so high that ArenaNet had to temporarily halt sales of Guild Wars 2 from its online store to keep servers playable.
