Final Fantasy X-2/Chapter 4/Airship Celsius

After the initial scenes, travel down to the engine room and collect the four chests there for Phoenix Down x7, Turbo Ether x3, Remedy x6, and Hi-Potion x8. Then ride up to the Deck and have a conversation with Paine. Now travel to the Cabin and speak with Barkeep to purchase/sell items and rest. Head back up to the Bridge when you have finished. Shinra will ask Yuna to check out the CommSpheres. Head over to his control station and speak with him again to find out more. He now has a new option in his list "CommSphere Network".

Most of Chapter 4 will be spending time on this network as the Gullwings have decided to take a step back to rest and think about what should be done next. Control the CommSpheres by directing the viewing angle with psx: neutral dpad or psx: Neutral lstick. Press psx: r1 to zoom and psx: S to exit. Some scenes may take some time to start up or require you to look around a bit or zoom in on a certain spot to trigger.

Use the CommSphere network to speak with Wakka in Besaid, then Dona in Kikika, and Maroda at Bevelle. If you gave the stolen "Awesome Sphere" from Kilika to New Yevon, using Mushroom Rock Roads CommSphere will result in someone throwing it into the ocean. If you sided with the Youth League, however, you can check in with Yaibal.

When you have viewed all four locations and spoken with the people there, exit the CommSphere network. Buddy should now be standing across from Shinra's station. Speak with him. The Gullwings will then decide to throw a concert and require Tobli's help. Speak with Paine after talking to Buddy and then check the CommSphere network for more transmissions. When you have finished communicating with all the areas, head down to the Moonflow to search for Tobli.

CommSphere Scenes
After talking to Buddy, all areas become available to view on the CommSphere Network. There are several scenes per location that can be viewed by reconnecting with the location again. Some scenes are worth some completion points while others are just for enjoyment. Do not skip any scenes that give you completion points (each one that does will be noted below) or you may short yourself if you are trying for 100%. Some scenes take a minute to begin or require you to zoom in on a certain spot.

Mi'ihen Highroad
When you view the Mi'ihen Highroad through the CommSphere network, Rin will come out of the Travel Agency and asks Yuna to help him investigate the recent happenings on the Highroad. He has set up more spheres for you to use. Switch through each location by pressing psx: R2. For more information about this mini game, visit the Mi'ihen Mystery page.

Mushroom Rock Road
Only available if you gave the stolen sphere to the Youth League during Chapter 2. If you didn't, a Youth League member will throw the CommSphere into the ocean.

Bevelle
Only available if you gave the stolen sphere to New Yevon during Chapter 2. If you didn't, soldiers will shoot at the CommSphere and disable it when you first try to use it.
