Otakon 2013 - Iron Maiden

As a STALKER:

Iron Maiden

Much as before with the armored behemoth clad in steel, so too was this one sheathed in metal. I knew not what manner of advanced exoskeleton she wore as her chosen means of protection, but I had a sneaking suspicion she was not from these parts. Rather than any elaborate shooter or rifle, she held but a small pistol in hand. She had a sense of place about her, and appeared to know more than she cared to let on on the inner workings of the zone. A shame I could not convince her to wander with me to Pripyat Stadium, just before the Monolithians opened fire upon our position.

Taken near Pripyat Stadium.

Commentary: I want to say Mass Effect, but I'm sure that's not the case. Either way, she wore the costume well, with a pretty face to match.
EDIT: So I've been told it's Calhoun from Wreck-It Ralph. I still need to see that movie.
