Hi,
That reminds me. I am using version 1.05 because when I installed 1.08 the game gained a bug which I did not appreciate. If you have installed 1.08 try the mission 'ice maze'. Unfortunately, I lose fixes and enhancements included in 1.08, but I prefer that to sucking seawater out of the periscope! I don't mind sucking seawater out of my snorkel, it's only an ounce, but I imagine sucking seawater out of a periscope would be an insurmountable task
