Spike TV got to see Thief (no, just Thief now, branding fans) in motion, too. You can see their encounter with it below, as you refresh yourself with delicious Doritos and Mountain Dew. I am contractually obliged to mention that our kid Adam has already played the game, and you can read about his experiences over here.
I quite like the whole peeking around the corner thing. But I am not sure about the slo-mo aim-assist power thing. Seems a bit… Dishonoredy?
