Deus Ex: Human Revolution is an action role-playing game first released in 2011. I have never played it before, but I've come across lots of artwork, trailers and videos of it. Recently I stumbled upon this page by Eric Bellefeuille (lead Art Director Presentation) which highlights some of the UI design in the game.
If you're ever looking for a gold themed UI, this is it! A lot of the UI is set in gold and black, and is characterised by bold outlines, angled shapes and soft glow finishes.
The only thing I'm not sure about is the icons, which I think could be styled to compliment the overall look a bit more. Personally I think they are a tad too playful. But in saying that I don't know what the brief was so who knows, maybe the game UI had different objectives.
Anyhow check it out for yourself, there's some nice elements in there worth noting.
