Using an entirely new game engine created by the Las Vegas-based developer Petroglyph, Star Wars: Empire at War features beautifully rendered land and space battles set on memorable planets such as Hoth, Tatooine and Dagobah as well as never-before-seen environments taken directly from the Star Wars films and expanded universe novels. Set a few years before the events of 'Episode IV A New Hope,' the game lets players rewrite history as well as experience the aftermath of 'Star Wars: Episode III Revenge of the Sith,' the creation of the Rebel Alliance, and Darth Vader's rise to power.
