Star Wars: Empire at War puts the power to command an entire war for the Star Wars galaxy in the hands of players, giving them the freedom to determine how they play the game within the completely scalable and accessible gameplay. Set a few years before the events of Episode IV A New Hope, LucasArts' new PC game lets players wage war on ground and in space, as well as experience the creation of the Rebel Alliance, the strengthening of the Empire and the beginnings of the Galactic Civil War.

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 Yavin IV, Tatooine and Dagobah, as well as never-before-seen environments taken directly from the Star Wars films and expanded universe novels. In the game, players choose to join either the Rebel Alliance or the Galactic Empire, building and setting up tactical forces to unleash upon the enemy in real-time 3D. Memorable Star Wars hero characters can be brought into the action to help turn the tide of the battle as players build, manage and upgrade their space and ground-based units, vehicles, troops and base structures.

All of the gameplay and action within Star Wars: Empire at War is persistent, meaning that strategic and tactical elements from previous events will have a permanent effect on the galaxy. In addition to the single-player campaign mode, the game includes a two-player campaign mode and online skirmish modes for up to eight players.
