The interactive comic that was included with the PlayStation 3 version of Mass Effect 2 to allow PS3 users to affect the story of ME2 without having the save files from the Microsoft-owned first game is now available on Xbox Live Marketplace for 320 MSP.
Mass Effect: Origins will allow players to do the same for the Xbox 360 version of Mass Effect 2, thought the comic only changes six plot points of ME2 - and none of it deals with the Geth. This is due to the fact that the story in the comic is more for Mass Effect 3, such as the decision whether to kill the Rachni Queen or not.
Origins is an interesting artifact, but otherwise, pretty useless for the Xbox 360 gamer whose ME1 save files changes over 700 aspects of the story in ME2.
