Mass Effect: Arrival – the pending DLC BioWare has been teasing all week on various social networking sites – has a March 29 release date.

Arrival tasks Commander Shepard with traveling to the edge of the galaxy in order to recover an important asset – an operative that has information on the imminent Reaper invasion. Admiral Hackett is noted as making a prominent return in the downloadable content, voiced by sci-fi star Lance Henriksen.

“All year, we have been extremely honored 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 of the 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.”

The DLC marks the last mission for Mass Effect 2 and will bridge the narrative gap between  ME2 and ME3.

Arrival will set you back 560 Microsoft Points/ $6.99 (estimated, as we're going off a U.K. announcement)  and offers up three new achievements/trophies for your trouble.
