The Rebels have just destroyed the Death Star, and the galaxy is in turmoil. In other words, it's just the time that you, an ambitious criminal genius named Tyber Zann, have been waiting for. Quench your thirst for power as you build and lead your own forces of scum and villainy. 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.

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, Super Star Destroyers and more). Take down anyone who stands in your way of ruling the Underworld, be they new battlefield heroes like Luke Skywalker and Yoda, or even your most bitter rival – Jabba the Hutt.
