In order to do so, he will have to assemble a crack team of the best warriors, scientists and hackers that the galaxy has to offer. As the top soldier in the entire galaxy, Shepard is the only one who can destroy that base and save humanity from the Collectors. These Collectors are taking the humans back to their home base, which is located deep in a star system that is seemingly impossible to enter. All the colonies are left mostly intact, but every single human has vanished without a trace. The hero of that game, Commander Shepard, was reported dead after an attack by a mysterious alien spaceship, but he is still alive and in the clutches of an organization known as Cerberus, a pro-human terrorist organization that the player battled in the prior game.Ī mysterious race of aliens known as the Collectors has been attacking human colonies.

The title is set two years after the original Mass Effect.

Mass Effect 2 has one of the most unique opening sequences in recently memory, and in interest of avoiding spoilers for those who've yet to play it, I'll gloss over the basics.
