In the first round of "choose our official female Shepard"-contest that Bioware did over on Facebook, the face of Captain Shepard in Mass Effect 3 was chosen (which didn't look anything like the old default Shep, but fair enough). Now it's time for round two, which is almost as important! We now need to vote on her hair colour.
Have a look at the various colours on display on the game's Facebook-page. Then vote on the red one, since that's a similar colour to how my (and thus, the real) Shepard looked in both Mass Effect and Mass Effect 2. Thank you.
