Mass Effect 2 Lair of the Shadow Broker DLC Release Date and Screenshots

BioWare's Chris Priestly stopped by the company's official forums to announce that their Lair of the Shadow Broker DLC for Mass Effect 2 will be released on September 7th. The addon will set you back 800 points, but it sounds like it might have more to offer than the others we've seen:
We are pleased to announce this morning that the next Mass Effect 2 DLC episode The Lair of the Shadowbroker will be available on the PC and Xbox 360 on Tuesday September 7 and will cost 800 BioWare/Microsoft points. Not only is this an excellent adventure through Illium and the shadowbroker's secret lair, this new DLC will add the Shadow Broker intel center, new research, and five new achievements and give fans from Mass Effect 1the chance to continue a relationship with Liara.
Four new screenshots from the DLC have been added to their media section, too.
