BioWare, a division of Electronic Arts, has announced that “Bring Down the Sky,” the first piece of downloadable content for Mass Effect, is now available for PC gamers to download free of charge.

Fully optimized for the PC, “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. Instructions on how to download and install the new content is available at http://masseffect.bioware.com/downloadablecontent/. “Bring Down the Sky” is currently available for international languages including English, Spanish, Italian and German, with additional language versions coming soon.

The storyline for the new content begins as 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.
