As the first human Specter – sworn defenders of galactic peace – your mission is to halt the advancing armies of a legendary agent gone rogue. But as you lead your elite team across hostile alien worlds, you will discover the true threat is far greater than anyone imagined.

Three hundred years ago the quarians created the geth, a species of rudimentary AIs, to serve as an efficient source of manual labor. But the geth rebelled against their quarian masters and drove them into exile. Now the quarians wander the galaxy in a flotilla of salvaged ships, secondhand vessels, and recycled technology. Other species tend to look down on the quarians, seeing them as scavengers and condemning them for unleashing a dangerous synthetic life form on the rest of the galaxy.

“Bring Down the Sky” is the first in a series of planned downloadable content that will further expand the Mass Effect story and universe. It includes a new uncharted world that introduces the deadly Batarian alien race, approximately 90 minutes of new gameplay and an original soundtrack.

Batarian extremists have hijacked a mobile asteroid station in the Asgard system, setting it on a collision course with the nearby colony world of Terra Nova. Only Commander Shepard can save the millions of innocent civilians before the asteroid completes its deadly descent.
