There are a bunch of ways to have something spoiled for you, but in this day and age, even your very own gaming console is a threat. That's right, you'd better throw that console right out the damn window to save yourself from Mass Effect 3 spoilers.
DLC for Mass Effect 3 has been detailed on Xbox Live Marketplace, but gamers have found that the description is a bit more revealing than they'd like. THIS IS YOUR LAST WARNING, NO BITCHING IN THE COMMENTS! D:<
Mass Effect 3: From Ashes allows players to "unearth lost secrets from the past" to add a member of the Mass Effect's Prothean race to Shepard's crew. Of course, attempting to purchase and download this DLC ends in errors, but it seems that previous rumors are to be confirmed, at least when it comes to digging up ancestral aliens and using them to kick Reaper ass.
