The AI Torpedos may be the last Holy Grail yet to be found for SH3 and SH4!
I don't know how others feel, but it bugs me to this day that someone has not found a way to actually get them without the problems involved.
Even SH5 is lacking on how the AI torps work!
Yes, SH5 has them but it's such a dismal thing that it's not worth much mention!
