Oh my - just got the bad ending, and it was rough. I mean, well done, but if you get it, you'll see what I mean. Still missing just a few trophies.
Sweet! They just told me that since I've finished both sides, I get all powers, good and bad. :D
Edit: aw, bummer. I have ACCESS to them, but I have to unlock them. Still, they gave me 15000 XP, so I'll probably be able to buy everything as soon as I unlock it.
Double-edlt: just did some math. That's not nearly enough XP. Oh, well. Good thing I still need to complete a bunch of user-generated content to get a trophy.
