Codename Iceman stinks. It's everything I don't like in adventure game wrapped in one, from copy protection puzzles, to having to follow procedure perfectly, to piloting a submarine with inferior 1990 controls, to a RIDICULOUS number of dead ends (some of the worst dead ends ever!) and last but not least, gambling! Maybe we didn't need such an unpopular game on GOG. There's a reason they made no sequel.
