Mass Effect 3 is getting day one DLC, called From Dust, apparently. The story comes from a US GameStop customer who purchased the DLC code in store when ordering Mass Effect 3. An image (from Joystiq) of the supposed code receipt can be seen below.
It must be stressed that the DLC claim has not been verified by either BioWare or EA, and until the subject is addressed by either of those companies, there is no confirmation either way for the existence for the ‘From Dust’ DLC.
Earlier today it was revealed that there will be a Mass Effect iOS game, which Peter covered here.
