With this mod you can have all 4 Civ Titans at the same time, but only in the Editor.
I didn't make them work in the game because you could have all 4 titans and that would be unfair.
I've also didn't make a new xpacklanguage.dll because without it the new units remain in the beginning of the units list so it's easy to find them.
PLEEASE review this file and my Floating Castle, since it was my first texture I made.
