Soulcalibur IV Soulcalibur IV is a fighting game by . This installment is unique to the series , as Namco and LucasArts came to an agreement to include Darth Vader ( exclusive to PlayStation 3 ) and Yoda ( Xbox 360 ) as playable fighters . Galen Marek , the secret apprentice of Darth Vader from " " , was also made an unlockable character under the name " The Apprentice " in both console versions ; however , his endings are different in the two versions ; the PS3 version is longer and features Darth Vader . On October 23rd , 2008 Yoda and Vader were both made downloadable content for the systems they were not natively on . Vader costing 400 MS points and Yoda costing $ 4 . 99 . These changes allowed Vader to be in the second to last battle of Yoda ' s story mode , and Yoda in Vader ' s . It also extended the ending of The Apprentice ' s story mode on the 360 version to that of the PS3 version . An Infinities comic titled " " was later published on StarWars . com to provide a possible explanation as to how Darth Vader , Yoda , and The Apprentice ( named Starkiller in the comic ) ended up in the " Soulcalibur IV " universe . Gameplay . Players control one of many selectable characters at a time to battle others . Modes featured include standard Story , Arcade , and Training modes , as well as a create - a - character feature and the new Tower of Lost Souls mode , which offers players the chance to participate in special battles to gain rewards . Unique to the " Star Wars " characters are Force abilities . Each of the three characters has a special Force Meter , which drains and recharges based on the players ' use of Force attacks , as well as different sets of abilities from the others . Darth Vader has been given Force push and choke ; Yoda uses the Force to propel himself higher into the air than most characters to unleash more complex aerial combos ; and The Apprentice utilizes various dark side attacks , such as Force lightning . One game level is " Star Wars " - themed and is called Star Destroyer Docking Bay ; it displays a space loading platform . A Lambda - class T - 4a shuttle is landed near the fighters . A Death Star can be seen in the background as well as a Star Destroyer and TIE Fighters flying in what seems to be a supposed space battle . Reception . Since its release , reviews of " SoulCalibur IV " have been mostly positive . Certain criticisms were aimed towards the addition of the several aspects of the " Star Wars " franchise , some commenting on their ' unnatural ' presence and that Yoda and The Apprentice were " broken " and " absurd , " respectively . Players were also disappointed that unlike the other characters in the game , whose outfits could be completely customized , the " Star Wars " characters were limited to one outfit that came with an alternate color scheme if two players picked the same character . In addition , while all the regular " Soul Calibur " characters had a variety of unique and visually distinct weapons to choose from , all of the " Star Wars " characters ' weapons were identical lightsabers with different particle effects . The online multiplayer mode , on both platforms , has also been subject to criticism . Poor network programming causes the auto - match feature to assign players to already full rooms or on - going matches , resulting in errors . Some say the best way around the error is to hold matches of their own and wait for an opponent to come along manually , which usually takes no more than a minute . A small amount of controversy resulted when it was revealed that the system - exclusive characters were not actually " exclusive " : Both versions of the game shipped with the code for both Vader and Yoda on the discs , and the hidden character could be accessed by hacking the game . The file that is downloaded when a player pays for the other platform ' s character is actually just an " unlock key " which activates the code which they already possessed .
