Ultimate Weapons

[Flashback007]

I have all ultimate weapons exept from Barrett en Caith Sith. Is there a way to get them when you already are on the third disc? I hope so.

[Kirobaito]

No. You get Barret's before you fight Hojo, and you have to have Barret in your party to do it. You get Cait Sith's the second time you go to the Shinra Tower, in the recreation area. It's in a locker.
