QUEST: Winging It
LOCATION: Yavin 4 – Great Temple
QUEST GIVER: Rebel Mechanic
Head to the Yavin 4 Great Temple and find and speak with the Rebel Mechanic. Apparently he is having a bit of wiring problems, that they keep jamming. It is our job to help fix this issue.
We can begin helping by going around the back of these shutters and destroying the boxes here to reveal a terminal for BB-8 to play with.
By using BB-8 on the terminal this will then open the shutters, which will then give us access to the wiring mechanism. Destroy the wiring mechanism by using a grenade.
We can then fix the Rebel ship behind us using the parts that were destroyed in the grenade blast.
By fixing the ship we can then complete the mission.
The BTL-A4 Y-wing ship will now be available to us for 100,000 Studs
