Literally moments ago, BioWare announced that brand spanking new and flashy Mass Effect downloadable content will be headed to the XBLM on March 10th and boy oh boy is it juicy good.
The Mass Effect Bring Down the Sky DLC pack will cost 400 Microsoft points and expand upon the Mass Effect story by introducing a new world featuring the Batarian race. According to the description, Bring Down the Sky will feature over 90 minutes of additional gameplay where a "Batarian extremist group has hijacked a mobile asteroid station in the Asgard system, setting it on a collision course with the nearby colony world of Terra Nova" and (of course) "only Commander Shepard can save the millions of innocent civilians before the asteroid completes its deadly descent." Intense stuff.
The new DLC will also pack one new achievement worth 50 Gamerscore and is confirmed to be the first of many planned Mass Effect expansion packs. We guess Surfer Girl was right about this one.
