Mass Effect 2 takes place after Mass Effect 1 and some fans were concerned they would miss out on some of the important story choices available in the first game. The Mass Effect team, working with the fine folks at Dark Horse Comics, has created an interactive in-game comic that allows players new to the franchise to experience Mass Effect 1 while making the story choices that have repercussions in Mass Effect 2.
There is a demo of Mass Effect now available on the PlayStation Network. You can learn more about the demo here. This demo lets you play the start of Mass Effect 2 as well as introducing you to one of your potential party members, Dr Mordin Solus. Dr Solus, or Mordin to his friends, is a salarian scientist who can not only heal the sick; he can create new exotic weapons to use in battle. Finding Mordin and recruiting him to join you and your suicide mission will not be easy.
Look for Mass Effect 3 to come to the PS3 in Holiday 2011.
