Re: is it possible to control underwater shooting ability
 

Lighting Demon's throw lighting works under water, as strange as that sounds. Burnsaber's UW mod was present though so I'm not sure whether it was the mod that enabled it or if it was originally possible.

Re: is it possible to control underwater shooting ability
 

Do you mean storm demon? I've seen storm demons and Tartarian Cyclopes throw lightning underwater without any mods. I don't think that helps me though, unless I were to put that lightning weapon on my units--which I don't want to do, because my purpose calls for a powerful, precise, earth-based attack, not a lightning-based attack. So I'm going with multiple Piercers until somebody finds a way to do this.

It's not a huge problem for me but it seems strange that the modding system wouldn't support this. I'd be very annoyed about it if I were trying to make a new underwater nation.
