"The Ballad of Gay Tony injects Liberty City with an overdose of guns, glitz, and grime," says Rockstar of the title.

"As Luis Lopez, part-time hoodlum and full-time assistant to legendary nightclub impresario Tony Prince (aka "Gay Tony"), players will struggle with the competing loyalties of family and friends, and with the uncertainty about who is real and who is fake in a world in which everyone has a price."

The Xbox 360-exclusive DLC hits this fall for 1600 Microsoft Points ($20). As with first expansion, The Lost and Damned, Gay Tony will require Grand Theft Auto IV to run.

Also announced was Grand Theft Auto: Episodes from Liberty City, a disc-based bundle including both The Lost and Damned and The Ballad of Gay Tony. The package is priced at $40, and will not require users to own the original game.
