Since Mass Effect was a Microsoft published game it’s not going to be released on the PS3 anytime soon. Luckily the fantastic sequel is getting put onto the PS3 by EA. To try and simulate the breadth of choices that come over from the first game they are putting in an interactive comic. The interactive comic will be part of the Cerberus Network ,for PS3 players only at this time, and will therefore only be available to people who buy the game new.
I am a huge Mass Effect fan and while I already own the game on 360 I am tempted to get this version because playing through Mass Effect 1 multiple times just to play Mass Effect 2 differently takes far too long.
