Rocket Town
Note: This portion of the strategy guide is for the second visit to Rocket Town. If this is your first visit to this town click here.
Make your way up to the Rocket from the entrance to town. You will find a bunch of guards blocking the pathway. Fight your way through them and get to the top of the Rocket. Once you’re finished killing all the guards you will have to find a way to squeeze Cid into your team, unless he’s already on your team.
You’ll have to fight Rude among the Shinra guards, but he’s pretty weak, so it barely counts as a boss fight. Just make sure you steal a Ziedrich from him. Inside the rocket will be one last fight, and then its time for blastoff!
Take Cloud and climb the ladder to go get the Huge Materia. Once you try to first crack the password on the control panel it will start a timer sequence, and you have until the time is up to get the password in. The correct password is:
Climb down to the back of the ship and hop into the escape pod. It’s time to make your way back to Cosmo Canyon.
Cosmo Canyon
Make your way up to Bugenhagen’s observatory on the top of Cosmo Canyon again. Bugenhagen can be found in his odd contraption. Talk to him once you find him.
A short scene will occur with all your team members in Bugenhagen’s observatory. Cloud will ask Bugenhagen’s permission to leave the Huge Materia at his observatory, and they will use his contraption to leave it “upstairs”. If you managed to gather all 4 of the Huge Materia, take a look inside the huge blue materia. Select “Get closer…” when you examine it and you will receive Bahamut ZERO Materia. Touch the Huge Materia again and select “Go back down” to get out of here.
You’ll now be taking Bugenhagen with you on the Highwind and will be making your way back to the Forgotten City.
