BioWare has announced that Bring Down the Sky, the first piece of downloadable content for the space epic Mass Effect is now available for PC gamers to download free of charge.

Bring Down the Sky, the first in a series of planned DLC, includes a new uncharted world that introduces the deadly Batarian alien race, an original soundtrack and approximately 90 minutes of new gameplay. 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. It's up to Commander Shepard to save the lives of millions of innocent civilians.

Bring Down the Sky can be downloaded by launching a registered copy of Mass Effect for the PC and following the instructions at the launch screen.
