Story: You are Commander Shepard, and your on the Normandy (your ship duh). Things happen, and you find yourself "Acquired" by a group of people called Cerberus. These people apparently were not your friends in part 1, but in this one, you work for them.
They have hired you to gather a group of people to find out why colonies of humans are disappearing. Humans, Aliens, Robots, dirty alien sex--it's all there.
