Take Two has announced that sales of the popular and critically acclaimed Grand Theft Auto 4 have surpassed 13 million copies sold worldwide.

Take Two also revealed that worldwide, the sales of GTA 4 are evenly distributed between the PS3 and Xbox 360, whereas in the US, where it has sold 5.5 million copies, the Xbox 360 version leads the PS3 by over a million games.

Take Two did not reveal how many copies of the “Lost and Damned” expansion were sold, but analysts have estimated that over a million have already been sold, and that it will sell another million by the end of October, when Take Two’s fiscal year runs out.
