BioWare has confirmed that “The Lair of the Shadow Broker” (the next piece of downloadable content for Mass Effect 2) will be released on the PC and 360 on 7th September. It will set you back 800 Allards on the 360 and 800 BioWare points on the PC, which works out to £6.85. The DLC adds Mass Effect 1 character Liara T’Soni as a party member.
Liara will be joining up with Commander Shepard to take down the Shadow Broker and rescue the man he kidnapped. Apparently, it will all take place on Illium and will offer new research, five new achievements and the ability to continue a relationship with Liara from Mass Effect 1.
