Mass Effect 3's Extended Cut has been designed to offer players more personalised endings that better reflect the choices they made throughout the trilogy.
Speaking at the Mass Effect panel at PAX East (via) Penny Arcade, Bioware producer Mike Gamble said: "To be clear, the Extended Cut is not a re-imagining of the ending or a new ending. We're currently building it right now, our cinematics team is on it. Our writers are heavily involved. It's coming together."
So while it won't change the endings per se, it will expand on them to provide "more clarity for those seeking further closure to their journey", as previously promised.
Gamble elaborated a little: "It's more than just a few cinematic scenes. We're happy to be doing it... We want to give more closure about some of the questions you have, and in general we wanted to give the players a sense of personalisation with the endings.
"Many people mentioned that some of the choices they made in the game are not necessarily reflected in the ending scenes. We're definitely going to focus on things like that. We want to make sure that when you see the ending of Mass Effect, you now have the information and context to be satisfied."
He added: "It wasn't in the game because we didn't know there was such a huge demand for it, to be honest with you."
