Crisis Core: Final Fantasy VII/06: Protect Your Honor

This chapter starts at Costa del Sol. The walkthrough assumes that you did everything (so if you don't receive a mail when it's mentioned in the walkthrough for example, it's surely because you missed something).

Costa del Sol
After some cutscenes and fights, you will need to go to Junon.

Junon
In Reunion, you'll get access to a new feature called Buster Sword Proficiency, it allows you to perform a Battle Stance by pressing psx: X + psx: S / +.

Lower Junon - Level 3
At the end of the road, there is a chest containing a Bronze Armlet. Just continue.

Lower Junon - Level 6
After a cutscene and a fight against another Genesis copy, you will need to go forward, you'll receive another mail from Kunsel in the way. Just continue forward.

Central Tunnel - Level 6
You'll get a cutscene and then a boss fight.

After the fight, another cutscene, and then you need to continue forward, grabbing two mails in the way.

Upper Junon - Level 6
There will be a cutscene, and then you will have to protect the door from incoming enemies, there are 30 of them, and you need to prevent them from approaching the door. Start with the closest ones to the door, and when you defeat the 30, it will be over.

Just after, don't go to the door but take the side elevator to Upper Junon - Level 8, it is to the southwest, near the door where you came from.

Upper Junon - Level 8
You'll get a cutscene, it's mandatory if you want to be able to join the last Fan Club, your own. There also are 5 chests, 2 to the east, 3 to the west. Now go back to the elevator.
