Bioware is not giving any details out about Mass Effect 2 yet, but they did release the above teaser trailer. However, everything may not be how it seems in the video because Bioware posted in their forums that you should keep your game saves from Mass Effect.
“This is just your first taste of Mass Effect2. We are not yet discussing the details of the game,” stated BioWare community coordinator Chris Priestly. However… don’t delete your Mass Effect 1 saves yet.”
So, maybe KIA is not the appropriate label for Commander Shepherd. Guess we’ll have to wait and see.
