Mission to Prefsbelt IV The Mission on Prefsbelt IV took place when the Rebel pilot Wedge Antilles , coordinated by General Madine , attempted to reclaim the Imperial shuttle " Tydirium " . Antilles infiltrated the Academy through the southern mountain pass and avoided detection by the Sensor Outpost s . He then docked with the shuttle and took off toward the rendezvous point . After his escort arrived , he escaped . Prelude . The Rebel Alliance required an Imperial shuttle to deliver a commando team on the moon of Endor . In 4 ABY , Rebel pilot Ace Azzameen managed to capture the " Lambda " - class shuttle " Tydirium " from Outpost 327 during the Mission to Zhar , but the Galactic Empire managed to recapture the shuttle soon after , and had it transferred to Prefsbelt IV . General Crix Madine sent Rogue Leader Wedge Antilles to the Imperial Naval Academy on Prefsbelt IV to steal the " Tydirium " for Rebel use . Mission . Madine ordered Wedge Antilles to approach from the south through the mountain pass , and told him the shuttle was parked at the northern Academy platform . Madine also cautioned him to avoid the Sensor Outpost s . Antilles was able to avoid detection by the eight sensors and moved into the next section of the Academy . He then abandoned his starfighter to steal a TIE / LN starfighter after eliminating the pilot . Antilles then infiltrated the Academy . He then proceeded to the Academy , passing the landing platforms and other installations and the AT - ST defenses . Near the Academy , he strafed the rows of TIE starfighters and the gun turrets , revealing his presence . He also flew through one of the other landing pads and acquired a vehicular upgrade . The Academy staff announced that the Academy would go on lockdown in four minutes , and the fighters were deployed . Antilles knocked out the four turrets guarding the shuttle , docked on the landing pad , and transferred to the " Tydirium . " Pursued by TIE fighters and interceptors , he flew toward the rendezvous point , where three pursuing fighters were eliminated by Antilles ' newly arrived escorts , two pilots from Rogue Squadron . Together they escaped the Academy . Aftermath . Some time after the mission , Rogue Squadron joined in a raid on the tibanna gas storage on Bespin . Alliance General Han Solo was able to use the " Tydirium " to infiltrate the Endor system along with his commandos , prompting the Battle of Endor . Behind the scenes . There were 2 versions of the mission in the 2001 video game " " ; night and day , depending on the GameCube ' s clock . During the night , you pilot a Speeder and during the day , a Y - wing . As there are two versions , this article incorporates only the information which appears in both missions , without specifying which version is official . If the player fails to capture the shuttle before the lockdown goes into effect , the shuttle will be lowered into the landing pad and the mission will fail . There are separate vehicle upgrades available in either version . For the daytime version , the player can acquire Advanced concussion missile s . The nighttime mission has the player acquiring Advanced spread proton bomb s instead . This article assumes the player picked it up during the mission . In the co - op campaign included in " " , both players have to board the " Tydirium " before the player can use it . The first player is relegated to the pilot cockpit , whereas the second player will use its aft gun to shake off the pursuing TIEs . The player may unlock the TIE fighter by capturing it in both versions , and there are separate upgrades to be found in the versions . This article assumes the player captures the TIE fighter as part of the infiltration . In the day version , the player must hit the TIE with the ion cannon , and in the night version , the player must shoot the pilot near an Imperial outpost . The player may choose to not capture the TIE fighter and continue in their starfighter . The player may also destroy any Imperial target as long as they destroy the four turrets guarding the shuttle . The player can also maintain cover up until they reach the loading platform for the " Tydirium " , with Wedge noting upon arrival that he can ' t steal the shuttle while the turrets surrounding the loading platform are still active . The recommends that the player conduct several pre - emptive attacks beforehand in order to gain a medal for the mission , and suggests using the Y - wing to do the attacks rather than the TIE fighter . The strategy guide also recommends that the player head straight to the rendezvous point , and this article follows that recommendation . Madine ' s opening dialogue is slightly different in each version . If the player steals the TIE fighter at night , there is a separate cutscene where Antilles picks up his speeder ' s gunner . " I ' ve found him . We ' re on our way " is Antilles ' alternate dialogue . There is no dialogue at the end of the day mission . The capture of the " Tydirium " was also featured in the 1999 video game " " , where it was stolen from an Imperial station by Ace Azzameen . The 2007 reference book " " attempted to reconcile the sources by saying that Antilles stole the shuttle while Azzameen acquired codes . Leland Chee , the Keeper of Lucasfilm Ltd . ' s Holocron continuity database , has stated that both thefts of the " Tydirium " occurred , and that the " X - wing Alliance " mission happened first .
