BioWare has released video for Lair of the Shadow Broker, which is slated to hit Mass Effect 2 next week.
In it, not only do you get the chance to "continue a relationship with Liara", but kill a bunch of bad guys as well.
PS3 owners can expect this to come along with the full game in January.
For the present, though, it's out on Xbox 360 and PC September 7 for 800 MS/BioWare points.
