Knights of the Sea Depths II:Ace Edition 1.4

Expand SH4 U-Boat Missions range of combat operations.

What is KSD ?
Quote from KSD II author
Initially, the idea was simple – to take the best, in my opinion, from SH3 (GWX, NYGM) and on the basis of SH4 U-Boat Missions (mission for the Germans) to expand the range of combat operations all the way to the Atlantic and from 1939, including additional types of boats and main combat fleets participating in the hostilities in the Atlantic Theater. The idea is not new, at one time it was worked out and is still being worked out in the Operation Monsun fashion.
