The title of this Thief video calls it a trailer, but I'd be hard-pressed to classify it as such. Not many trailers run six minutes, but whatever this is, it remains interesting the whole time. I guess badass thievery and murder have that charming allure.
While teaching the art of the trade, this video runs down the different approaches you can take to get what you want. And you want everything that isn't already yours. If it doesn't have you thinking about past Thief games, it's certainly reminiscent of Dishonored. Just remember that the shadows are your greatest ally.
