I'd say it bleed out I mean it's near to "can't be done" to code anti ship misslies for sh4. I don't think it can be done. Not to mention torps that will fire in deep water, and also the sonor to find the enemysubs. The Sh4 game code and engine just wasn't made for it. I think a WWI mod is the best we can hope for. I'd love for someone to prove me wrong though buy making it happen and recoding the whole game. Good luck to who ever you may be.
