Second GTAIV episode named, detailed

Plus: standalone two-episode disc also due.

Rockstar has announced that the second Xbox 360-exclusive downloadable episode for Grand Theft Auto IV is called The Ballad of Gay Tony and is due out this autumn.

As with the first episode, The Lost & Damned, it will set you back 1600 Microsoft Points (GBP 13.60 / EUR 19.20).

What's more, the launch will be matched at retail by a new disc release, Grand Theft Auto: Episodes from Liberty City, which includes both releases for USD 39.99 and will not require a copy of GTAIV to play.

The Ballad of Gay Tony puts you in the boots of Luis Lopez, "a part-time hoodlum and full-time assistant to legendary nightclub impresario Tony Prince, aka Gay Tony". You'll have to deal with the competing loyalties of family and friends, and trying to establish who is genuine and who is fake. Rockstar promises "an overdose of guns, glitz, and grime".

"Liberty City is the most vibrant game world we've created yet. The episodic structure has allowed us to interweave stories, gameplay and atmosphere in a whole new way," said Sam Houser, Rockstar founder, to mark the announcement.

"The team at Rockstar North have yet again surpassed themselves, and made something that is both epic and very innovative. This episode's focus on high-end night life contrasts with the biker gangs portrayed in The Lost and Damned, whilst giving us a lot of new gameplay possibilities."

The announcement of The Ballad of Gay Tony also lays to rest rumours that the second episode would be called "Blood and a Four Leaf Clover".
