Mass Effect 2 Lair of the Shadow Broker DLC Preview

I have a sneaking suspicion that Lair of the Shadow Broker is going to turn out to be Mass Effect 2's best DLC, and the contents of this new preview on IGN don't seem to dispel that thought process.
The storyline of Lair of the Shadow Broker is consistent with the darker tone of Mass Effect 2. Liara is no longer the naive girl prone to sequestering herself in Prothean dig sites. She's become noticeably hardened and hell-bent on getting revenge, and rightfully so. If you've read the Mass Effect: Redemption comic series following the actions of Liara after the Normandy SR-1 is destroyed, you'll already be caught up with her situation and motivation. If you haven't, the game sets up the circumstances for you, though not in as much detail.

To sum it up, Liara worked alongside her partner, Feron, and Cerberus to retrieve Commander Shepard's body from the Shadow Broker's possession before he could sell it to the Collectors. In the process, Feron was captured and Liara is hopeful that her former Drell partner is still alive on the Shadow Broker's ship. After years of tracking, Liara finally gets her big break a Salarian named Sekat has discovered the location of the Shadow Broker. That's all I'll say story-wise to avoid spoiling the experience, but you can expect a well-written narrative with twists and turns.
