Update: Oops Mass Effect 3 DLC rears its head early on Xbox Marketplace and spoils a major plot point

Tonight the boys over at EA are set to slap Microsoft.

In the last few hours a listing on the Xbox 360 marketplace has set the internet gaming community alight. The listing has inadvertently revealed one of the first pieces of downloadable content (DLC) for Mass Effect 3. That wouldn’t be so bad if it wasn’t for the fact that in the process it has also spoiled a “MAJOR” plot point from the upcoming game.

Warning: Don’t read on as it contains spoilers about the nature of the DLC.

Mass Effect 3: From Ashes, has no exact release date and will apparently allow players to “unearth lost secrets from the past” and enlist a member of the game’s Prothean race.

Whether this is the same DLC we reported about recently but under a new name, or a second DLC that will be released alongside we don’ know.

When we tried to download the DLC, surprise, surprise we received an error message saying, “Cannot retrieve information from Xbox LIVE”. The DLC was even available on the website for a split second  -Mass Effect 3: From Ashes.

We’ve reached out to BioWare for comment and will update as soon as we hear anything.

Update: BioWare Associate Producer Michael Gamble went on to the company’s  official forums this morning to discuss the disastrous leak:
