The Art of Gears of War 3 has just been released by Ballistic Publishing.
The 320 page book takes you behind the scenes of the third Gears game, with concept and production art, as well as cinematic screens.
The soft cover edition is available from Forbidden Planet for £49.49, but if you want either of the more luxurious Special Leather or Folio editions you'll need to head over to Ballistic's website.
