Star Wars : Empire at War : Forces of Corruption Star Wars : Empire at War : Forces of Corruption is an expansion of " " . It was announced on May 9 , 2006 at E3 . The expansion adds several new maps and units , as well as an additional storyline revolving around the conquest of Tyber Zann and new types of gameplay , including playing as the Zann Consortium , a powerful crime organization and syndicate . It was released on October 24 , 2006 in North America and later released with the base game as " Star Wars : Empire At War Gold Pack " on Steam on 25 May 2010 . It was Matthew Sloan ' s first game to voice Darth Vader . Gameplay . Campaign . The campaign follows the conquest of the intergalactic crime lord , Tyber Zann , and his underworld organization , the Zann Consortium between the events of the destruction of the first and second Death Star and right up to the climactic theft of the " Eclipse " , an " Eclipse " - class dreadnought . Tyber Zann corrupts planets with his Defiler s in order to obtain information of the other two factions , sabotage , and to gain credits . In the campaign , Tyber also tries to unlock the secrets of an ancient Sith holocron , which Silri later uses to find the ancient Carbonite Sith Army . Galactic Conquest . Galactic Conquest gameplay remains very similar to the original Star Wars : Empire at War with a few major changes . The Zann Consortium ' s new corruption element is a new feature which provides bonuses to the competing factions in addition to the benefits provided to the Zann Consortium . Units produced from Cantinas and using bounty hunters to neutralize heroes cost significantly less on corrupted planets . As an additional bonus to Rebels , smugglers do not expire on corrupted worlds . Also , the original Death Star no longer appears , being replaced by the second one after being destroyed in the original game . The same goes for Red Squadron , which has been reformed into Rogue Squadron . Alderaan is now an asteroid field . Rather than being mod - only , as in the first game , the " Executor " now is fully playable in Galactic Conquest mode , and is the most powerful combat unit in the game . Also , when a faction wins the war ( e . g . , all enemy planets are captured / destroyed , both enemy leaders are killed , etc . ) there is no end cutscene ; the game instead skips immediately to the credits , unlike in the last game . However , this may be due to the fact that , unlike in the last game , there is now only one story mode ( Zann Consortium ) and thus one end cutscene for both the story and Galactic Conquest , which , in the case of the latter , may not be an appropriate ending based on the way the player won the mode . Skirmish . Skirmish has been changed slightly , while still keeping to the original game . One major difference is 3 faction battles , and the ability to fight the same faction ( mirror battles ) . Land skirmish battles feature a new base building mechanic – outposts . Outposts can be captured like buildpads . Once captured , outposts build one of 3 structures , depending on the faction . The Mining Facility and Hutt Palace can be built by any faction while the other structure is unique to each faction : Repulsorlift Jammer ( Zann Consortium only ) , Uplink Station ( Rebellion only ) , and M - 68 planetary magnapulse cannon ( Empire only ) . Space skirmish battles are also similar to " Empire at War " , with some differences . When an outpost is captured by the Zann Consortium , it can build a " Venator " - class Star Destroyer instead of the " Interceptor " - class Frigate that the Rebels and Imperials get . Multiplayer . Mulitplayer has advanced since the original game , bringing in new maps and new teams . Players using the same version as you appear in blue , orange for password only games and red for locked games . Critical reaction . While many critics and gamers welcomed the new expansion , some decried it as being overly buggy — one particularly glaring bug that was pointed out often was the announcement of a ysalamiri cage constructing when an enemy fleet was incoming . Also , Garm Bel Iblis ' s " shield flare " ability can glitch and cause the particle to remain for the duration of the battle . Both of these glitches were fixed in the 1 . 1 patch . A less noticeable but equally glaring error was where only the cannon barrel of the Imperial Bp . 2 Anti - Infantry Turret would rotate when targeting and firing on a nearby enemy , but in the base game the entire top of the turret rotates properly , leaving few possible explanations . There was even a bug where , in campaign , the player loses his or her main characters and cannot continue . This was fixed in a patch . Cut content . The following items were cut from the final version of the game , but are still mentioned in some of the game files . Some of these items are restored via mods .
