In this second act the devs plan to "throw rocks" at our lead protagonist, where the first "introduced" dark elements the second will be really "exposing" them.
The idea is to give the player a view on "how scary" the Mass Effect universe is, "on the scale" they've been talking about. Now lore is established, they can "beat up the hero".
"We look at each game in the Mass Effect trilogy as a three-act story," producer Casey Hudson told . "But then as a trilogy we have our three acts. So Mass Effect 2 is the dark act. It's an opportunity to really explore the tougher, more brutal parts of the universe."
"They say in the first act you put a guy in the tree, in the second act you throw rocks at him, and in the third act you get him down."
"That's the fun of the second story is that now we know who these characters are, we know what the situation is and we can really beat up the hero of this story and take you to the most brutal parts of the Mass Effect universe," he continued.
"In the first game, it definitely introduces a lot of really dark ideas," explains Hudson, referring to the sentient machines known as Reapers who enjoy a bit of galactic genocide.
"That's really dark. But you just get a peek into it in Mass Effect 1. In Mass Effect 2, it's about really exposing that and letting you see it and letting you see how scary that would be when it's on the scale we're talking about." BioWare will be showcasing Mass Effect 2 at E3.
