PC.IGN.com has posted a new movie trailer of Emperor: Battle for Dune, showing off the 3D real-time strategy game that is nearing completion at Westwood. The 11MB trailer runs for a bit under a minute in MPEG format, and offers a mix of in-game and cutscene footage, as well as a little promo that pre-ordering the game at certain online retailers will get you three free new units.
