It shouldn’t come as much of a surprise, but this week’s Extended Cut downloadable content for Mass Effect 3, which adds new sequences to the game’s ending and epilogue, will not be the last time BioWare will ask you to turn on Mass Effect 3 again.
"Would now be a good time to talk about how we're doing more DLC in the future?” said Mass Effect producer Michael Gamble on Twitter last night. “That was a trick question. We'll save the future DLC for future chats. Don't worry though...there's much more.”
It appears we may already know what the (first?) downloadable content is about, too. An inquisitive user on the BioWare message boards looked into the data featured within the Extended Cut, and found evidence of a new mission related to Leviathan, which appears to be a dormant, rogue Reaper mentioned in both Mass Effect and Mass Effect 3.
