Question on difficulty settings
 

Iam trying to play the game with map contacts off but not 100% realism which drops me in the custom difficulty settings.

So my question when a new career is started are the only difficulty settings that you can select the low, medium , high and realistic ?
If so, am I going to have to play at 100% to switch off the map contacts or is If I select nothing will the custom option I chose before starting the new career kick in.

thanks

No, you can adjust your settings each time you are in bunker, just before to talk with the officer for next mission.
