U-Boats in SH4
 

My apologies if this is well and trly covered elsewhere... Is there a way of playing the u-boat types from SH3 in SH4? IE all the better graphics of SH4 but the SH3 boats?

Many thanks for help in advance...

Also (again my apologies if already in existence..) Is there a forum with just links to downloadable ships and subs?

Operation Monsun

It has a variety of Type II, VII and IX's and covers the whole war.

U-Boat module from UBI
 

Ubisoft put out their U-Boat module for SH4.

I'm not sure if OP Monsun requires it or not.

Yes it does.
You'll need the UBM expansion to play OM TorpexXIII.
Thanks raymond6751, I forgot to mention that.
