Arrival

Arrival is an upcoming DLC pack for Mass Effect 2. It was accidentally revealed on February 21, 2011 by the addition of three new trophies in a patch for the PlayStation 3 version of Mass Effect 2. While the addition of the trophies was intentional, BioWare assumed they would be invisible. BioWare released the first screenshot of Arrival on March 14, 2011, officially confirming the existence of the DLC pack. Arrival will be released on March 29, 2011 and will cost 560 Microsoft/BioWare Points, or $6.99 on PlayStation Network. Admiral Hackett will be returning and will play "a prominent role" in the pack.
