A pre-Mass Effect 3 DLC was confirmed by Bioware’s producer last year. The DLC will be invaluable for all who want to understand the events that happen between Mass Effect 2 and Mass Effect 3.
One of the DLC packs (there will be several) is planned for this summer. As far as we know, in Mass Effect 3 the player will have to protect planet Earth and kick some alien asses in London. The events that lead to the occupation of Earth will then be explained in the DLC’s.
So, for the time being there’s going to be a continued stream of DLC for people. We’ll start to have packs that’ll tell the story between Mass Effect 2 and 3. But beyond that we kind of have to see how people are responding to what we have and go from there -Casey Hudson
Maybe they will also use the DLC’s to introduce some off the new characters and enemies that will appear in Mass Effect 3? Some of the old characters and enemies will of course also appear in ME3.
If you look at some of the close-up shots of the Mass Effect 3 trailer you can identify a husk:
What characters/enemies do you want to see return in Mass Effect 3?
