The Mass Effect 3 From Ashes DLC was accidentally, and briefly, sold on Xbox Live Marketplace.
The download content named From Ashes contains an extra squad member. Spoiler below.
The From Ashes Xbox Live Marketplace page has now vanished and those who saw the content before it disappeared said it measured 628.18MB and cost 800 Microsoft Points.
BioWare associate producer Michael Gamble later confirmed on the company's forum that From Ashes will be available to buy at launch on all platforms. Let's hope the Prothean squad member is more deeply integrated than Mass Effect 2's DLC character Zaeed Massani, whose conversations were largely non-interactive.
The official release date for Mass Effect 3 is scheduled for March 6 of this year.
If you cant wait that until then the official trailers below!
