Custom realisim
 

Is there a way to select a custom level of realism, like in SHIII? Or am I stuck with the defaults of Easy, Normal and Hard? I've tried to set them, but they don't seem to carry over to the campaign modes.

set them in port (NOT at a refit), very left side of screen top shelf on cabinet, a clock.. put mouse over it: "options".

pick your poison, don't forget to save.

happy hunting

The settings in the main screen don't transfer to campaign mode. You need to adjust settings after getting to the office in campaign mode. You will only be able to change the game play options while in the office between patrols.
