In what is looking to be the best bit of Mass Effect 2 DLC to date, "Lair of the Shadow Broker" becomes available for download next week, on September 7, 2010. This DLC focuses heavily on Liara T'Soni, Shepherd's old friend, and the lengths she's gone through to help Shepherd throughout the years of their friendship. Watching the video, I was reminded how the story of ME2 barely touched on Liara's involvement in Shepherd's resurgence (sorry, didn't want to spoil anything for the PS3 guys who haven't played this yet, so had to come up with an idiotically vague word). I guess that is what they're looking to cover in this lore-rich story.

Anyway, Bioware released the trailer for this bit of DLC today, which you'll find after the break. It will retail for 800 Microsoft/Bioware points (or $10). It will also come on the Mass Effect 2 PS3 game disc come January.
