I keep a separate SH3 installation for my modding tests. Here's one of them.
Some things to keep in mind:
1) My "friend" here can move at varied depths and even surface.
2) This is not an MP match - it's a shot of an AI object.
3) He can be spawned by radio messages once you sight a convoy.
4) He has some freedom of movement, and will not move like a train on a track, as many of the current AI units do.
4) He can actually launch attacks against enemy units, and will retreat when he's out of torpedoes.
Hopefully, more developments later...
