It'll cost 800 MSP or BioWare Points on Xbox 360 or PC respectively. We get an intel centre, some new research and 5 new achievements.
This is the most expensive DLC content yet for BioWare's super sci-fi series. Liara T'Soni is out to hunt down the Shadow Broker and enlists the aid of Shepard and the Normandy crew. This also gives the chance to continue a relationship with Liara.
"Liara T'Soni is tracking down the mysterious Shadow Broker, and no one is safe. She'll do anything to recover the man the Broker kidnapped... and the Shadow Broker's agents will do anything to stop her. Team up with Liara and chase clues from the luxurious heights of Illium to the Shadow Broker's own secret lair," goes the BioWare .
She won't become a new permanent crew member, unfortunately. Have you been keeping up with Mass Effect 2's DLC catalogue?
