http://www.gamespot.com/news/6185640...ewstop;title;1Titled Bring Down the Sky, the update will include a new uncharted world and the introduction of the Batarians, the scheming alien race who clashed with humanity in the prequel novel Mass Effect: Revelation. The aliens have hijacked a mobile asteroid station in the Asgard region and set the ship on a collision course with nearby colony planet Terra Nova. Naturally, Commander Shepard is dispatched to foil the plot.
But while Bring Down the Sky is relatively cheap at just 400 Microsoft points (£3.40 or$5), it is also fairly short, adding only around 90 minutes of extra gameplay. Available on Xbox Live on March 10 at 2 a.m. PST, the game will also add an extra, as-yet-unnamed achievement worth 50 Gamerscore points.
I just got the game a week ago and i'm hooked. Great story and graphics. It took me a while to get into it, but once I figured how to play it, it's been non-stop. I think i'm about 80% through. I've been doing all the side missions.
