This DLC package is a great addition to Mass Effect 2 and shouldn't be missed.
The good:
-Excellent storyline featuring Liara T'soni from the first game.
-The graphics and settings are beautifully designed and add more depth to the location Illium.
-Boss battles are intense and fast paced.
-A skycar action sequence will surprise you.
-Top-notch voice acting adds much emotion and drives the story.
-Roughly two hours worth of play. A good length for a single mission and a DLC package.
The bad:
-A bit overpriced.
-Some combat/action sequenecs should have been longer, while others could have been shorter.
-Any other party member besides Liara doesn't participate in the storyline at all.
