Ready At Dawn, developer of the upcoming PSP God of War title, has announced that its Daxter game has sold 2 million copies.
Daxter, the company's first title, was originally released in 2006.
The game was later bundled with the slim model PSP - ceramic white in Europe and silver in the US - and was the best-selling PSP entertainment pack by a wide margin, according to Ready at Dawn.
Daxter was also branded as a Greatest Hits title last year, which may have helped the title reach its biggest increase in sales during the holiday season.
Ready at Dawn's second game, God of War: Chains of Olympus, is scheduled for release on March 4.
