Mass Effect 2 officially launched just a few hours ago, and BioWare and EA already have a slew of content available for folks who are part of the Cerberus Network and who preordered the game.
Yes, if you preordered at select retailers (or made good on a late night Microsoft error), you should have some free armor and/or weapons to play with. If you bought the game new (or bought it used and paid for the content on the Xbox Marketplace), you'll have access to one new mission on the Cerberus Network. Another is coming later this week along with a different character. Rather than make you wait and wonder about what all that wonderful content is, IGN is going to break it down for you right here.
