Grand Theft Auto IV: The Lost and Damned will cost just 1200 Microsoft points (10.20) for one week only from August 24th.
The DLC for GTA IV typically costs 1600 Microsoft Points (13.60), and its price cut is part of Microsoft's regular Xbox Live ‘Deals of the Week', which the firm has been running for some time. The offer is only available to Gold Members of its online service.
GTA IV: The Lost and Damned was released back in February, and is the first of two DLC packs for the game. The second pack, The Ballad of Gay Tony, is due for release on October 30th – both DLC require a copy of GTA IV to run.
Rockstar is also set to bundle both DLC into one retail box for release on October 30th. The boxed copy does not require a copy of GTA IV to run.
