Well, on the bright side, with all arcade aspects (or should I say the unrealistic WW2 era detection gear enabled) the game is a good platform for a nuke sub mod. Like the ones done for SH4.
So maybe this game is written to transcend more than just one time frame, though the time frame it's originally written for is limited in its scope.
Relying on modders of course. Has Ubi said anything yet about fixing some more of the bugs?
