This game is freaking hard. I had a crewman drown while repairing the number 2 reactor pump. If I were an actual submariner I'd probably know the casualty procedure but as a layman I have no idea what the hell I am doing. Ultimately I did figure out I had to open a bulkhead leading to a bilge pump but I was too depressed to continue long enough to find out if the huge radiation dose my other crew received would kill them.
Great game though. I like the thought of being able to create your own fantasy submarine. What If: the USA decided to try their own lead-cooled reactors like the Alfa class? I have a certain fantasy of a privateer submarine. Maybe if I gain some experience in this game I will give it a shot.
