Star Wars® Empire at War™: Forces of Corruption™
Following the success of Star Wars: Empire at War, the best-selling PC game of Q1 2006, LucasArts announces an expansion pack titled Star Wars Empire at War: Forces of Corruption. A widely appealing strategy game, Empire at War let gamers play the light side or the dark side in an epic Galactic Civil War. Now, for the first time ever, Star Wars Empire at War: Forces of Corruption introduces a unique point of view – the corrupt side.

The Rebels have just destroyed the Death Star, and the galaxy is in turmoil. As an aspiring Underworld figure named Tyber Zann, spread corruption throughout the galaxy using new strategic gameplay elements to influence other factions, steal their funds, slow their production, spy on them and more, all en route to becoming the most notorious criminal leader since Jabba the Hutt. Exciting new land-tactical options like customizable, upgradeable bases and guerilla warfare allow for innovative battlefield tactics. Take command of and confront new fighting units for all factions (Rebel B-wings, Imperial TIE interceptors, Darth Vader’s Executor Super Star Destroyer and more), and take down anyone who stands in your way of ruling the Underworld, be they new battlefield heroes like Luke Skywalker and Yoda or the forces of your most bitter rival – Jabba. Destroy capital ships with the awesome firepower of the second Death Star, and satiate Tyber’s drive for the deadliest capital ship in the galaxy, a devastatingly powerful Super Star Destroyer known as the Eclipse.
