Converting AI subs to playable
 

As the title suggests, I'm trying to make an AI sub playable! Perhaps a Japanese midget sub? Well.. The specific sub I'm trying to do is a Sen Toku I-400 class submarine. A mod.

Does anyone know how I could make it playable? :T

I DO NOT HAVE THE U-BOAT MISSIONS ADDON.
