To coincide with E3, Square Enix and Eidos Montreal have released their first official trailer for the upcoming Thief. Oddly enough the teaser is fairly similar to the trailer, although of course the trailer below is live action instead.
Sadly there doesn't appear to be any gameplay really shown in the trailer, so hopefully we'll find out a bit more at E3 as currently it's completely unknown to what the game will actually be, and play like.
Thief will be available on Xbox One, Playstation 4 and Windows in 2014, fingers crossed that the new Garrett is good enough.
