Well, my suggestion is:
'For example, a submarine vs submarine fight, the attacking submarine attacks from the back, or front, and the attacking sub is
firing torpedoes, then I think it would be cool to send special torpedoes back that can hit the attacking torpedoes. So
you intercept the torpedoes. The only thing what I think it would be good when you balance it, is the splash damage is
pretty high for the defending submarine.
Sorry for my bad english >.< I hope someone understands what I mean.
