A lot of people have been bitching about not being able to discover the full map of Coruscant. Currently it’s not possible to discover Coruscant Spaceport without playing hide and seek. It’s not known if it’s a bug or it is supposed to be like this, but here is a guide to discover Coruscant Spaceport and thereby the full map on the planet.
It turns out that in the docking bay there is a set of stairs off to the left (facing towards the elevators) run up the stairs to the viewing platform and looking out towards the docking bay you will notice two support beams on either side. I ran up the beam on the right into the ceiling, you will break through the ceiling and be able to see above the roof… way a bit and you will discover the entire map! (assuming this was the last bit you had) check out the picture guide below:
Go to the Shuttle Docking Bay here:
Climb the ramp(south) up to the balcony here:
Climb this support beam to the top:
Near the top, you’ll pop out above the ceiling and discover “Coruscant Spaceport”
