We may not be able to tell you what Tali looks like, but how about we settle for showing you one of the new squad members in Mass Effect 3? Pictured above is James Vega (previously named James Sanders), an alliance soldier who will join Shepard in his final battle against the reapers.
Gaze upon him, in all his faux-hawk, muscled, tattooed glory. Kinda looks like a meathead, no?
