This is Videros, a cosplayer from Germany. You needed that intro because, for all intents, he may as well actually be Deus Ex star Adam Jensen, complete with future pants, fancy jacket and snappy sunglasses.
About the only thing he's missing is a shot of him eating cereal, but it looks like it was taken at a convention, so we'll let that one slide.
For more great Deus Ex cosplay, see this previous post.
