Mission Walkthrough
You'll arrive at the Palace. Destroy any enemies around you, then investigate several areas, including the gates to the palace, the blue plate next to the switch in the south, the stall to the southeast next to the exit, and the pile of timber next to the door.

Make sure you also check out wall next to the much easier to reach scaffolding on the eastern side of the street before you leave.

At the Agrabah Gate, again vanquish your foes and investigate. This time, check out the massive pile of sand in the southeast corner, and the north corner of the short alley on the eastern side, as well as the boarded door on the same wall (Kingdom Hearts veterans will remember it as the entrance to the Back Alley room). Xigbar will then ask questions; the answers do not matter. More enemies will appear after the conversation.

Head back to the Palace, but make sure you enter through the upper gate in the northwest to witness the cutscene. You will reach the standard goal; to reach the final breakthrough, investigate the Palace Doors again, as well as exit into the desert at Agrabah Gate. Once you have done this, your mission is complete and you can RTC
