Every day, more details are emerging surrounding the multiplayer modes in Mass Effect 3, yet today's news isn't the exciting type.  The retail version of the game will include a code to unlock the Galaxy at War multiplayer mode, so if you buy the game used, you'll need to pay extra to unlock that feature.  The latest edition of the BioWare Pulse—shown above—has some other nuggets of information, such as some of the races and classes you can be in Mass Effect 3's multiplayer.  Cue thousands of blue-skinned Asari in three...two...one.
