Real Time Worlds confirmed today that it has raised $50 million in venture capital to fund its online gaming ventures.

The Dundee, Scotland video game studio will use the second round of funding to develop games such as “All Points Bulletin,” a massively multiplayer online game. The firm also has an office in Colorado.

The round was led by Maverick Capital and existing investors New Enterprise Associates and WPP also participated. Real Time Worlds is run by founder David Jones, the creator of the original Grand Theft Auto game that has become one of the biggest video game franchises of all time.

The company has more than 200 game developers on staff and it produced the hit Xbox 360 console game “Crackdown,” its debut title, in 2007. The game sold more than 1.4 million units, which means it generated roughly $84 million at retail.
