BioWare has announced that Mass Effect: Arrival, the final mission for Mass Effect 2, will be available for download on March 30, 2011.

In Arrival, Commander Shepard is sent to the edge of the galaxy to rescue an undercover operative who may have evidence of an imminent Reaper invasion that has been looming since the very beginning of the series.

Returning and playing a prominent role in Mass Effect: Arrival is Admiral Hackett, who is voiced by science-fiction actor Lance Henriksen.

“All year, we have been extremely honoured and humbled by the reception we have received for Mass Effect 2 from players around the world, including our post release DLC”, said Casey Hudson, Executive Producer, Mass Effect series.

“Mass Effect: Arrival is an exciting extension to Mass Effect 2 and will show players just how close the Reapers are to returning and completing their deadly harvest.”

Mass Effect: Arrival will also include three new achievements for Xbox 360 and PC, as well as three new trophies on PlayStation 3. The DLC pack will be available for 560 MS Points on Xbox 360, $11.45 on PSN and also available for PC for 560 BioWare Points at BioWare's social website.
