My brother told me that a patch is going to be released for ME3 which features the ability to import your own face (or anyone's face) from a photo and wrap it around the 3D model of the "Shepard" character.
I haven't heard of that.
There was this option to do this for Tony Hawks undeground on PS2. It was quire complicated. You needed to send your face to activiosin and stuff. If I remember correctly.
So technically I think it's possible.
Maybe he was mistaken, because Bioware is releasing a patch that fixes the face import glitch from previous ME titles.
I'm not sure if that's released yet.
