Take that, Halo 3:

"Grand Theft Auto IV" raked in more than $500 million in its first week in stores, selling more than 6 million units worldwide, the video game's publisher said Wednesday.

The highly anticipated title from Take-Two Interactive Software Inc. has received stellar ratings along with criticism for its violent content.

The title sold about 3.6 million units on April 29, its opening day, bringing in roughly $310 million. This is $10 million more than what Microsoft Corp.'s "Halo 3," another blockbuster game, took in during its first week last fall.

More than 2.3 million people played [the game] on Microsoft's Xbox Live online service.

Just so that's clear: GTA4 sold more on opening day than Halo 3 did in its entire first week on the market. Unbelievable.

Thanks Dave. :)
