Rubini's torps work better is SH3 than they do in SH4 (translation problem??), but even if they're buggy, it's still a serious threat to a submarine. Since you cannot "see" what weapon a particular airplane carries from an initial spotting distance, you have to think to yourself: does he have rockets, or does he have torpedoes? Well, punk? Do you feel ~lucky~?...
so, you crash dive and hope for the best...
gap, if you can make the torps or the rockets - or both, disappear, you'd be "even more world famous-er" in my book, brother... |;^)
