Rockstar Games has now shipped over 13 million copies of Grand Theft Auto IV worldwide for PS3, Xbox 360 and PC.
That's according to motherpublisher Take-Two's latest financials, which also reveal that the Carnival Games titles have shipped over four million units worldwide.
Although Take-Two posted first-quarter revenues of USD 256.8 million (up by a little over USD 16m), its losses also went up from USD 38m to USD 50m, blamed on marketing, legal and R&D costs.
The publisher attributed the good news bit to strong sales of the abovementioned games and Midnight Club: Los Angeles, also from Rockstar.
However, in a subsequent conference call with investors (thanks GameSpot), there was no word on sales figures for the recently-released Xbox 360-exclusive Lost and Damned DLC for GTAIV, which analysts predict has already done over a million sales.
