The Rebel smugglers do not expire on corrupted worlds. The cost of recruiting Cantina units and deploying bounty hunters to neutralize heroes is lower on corrupted planets. The Zann Consortium's Corruption ability provides bonuses to all factions in addition to the benefits provided to the Zann Consortium. Galactic Conquest gameplay remains very similar to the original Star Wars: Empire at War with a few differences.
Tyber Zann corrupts planets with his Defilers in order to obtain information, credits and to sabotage enemy structures. It is set between the events of the destruction of the first and second Death Star and ends just after the theft of the Eclipse-class super star destroyer by the consortium. The campaign is similar in structure to the Rebel Alliance and Galactic Empire campaign in the first Empire at War game but this time it follows the story of the intergalactic crime lord, Tyber Zann, and his organization, the Zann Consortium.
