Steel Tide

In this game you are the admiral of a submarine during a fictionalized WWII, tracking and destroying "Souverian" (aka Nazi) subs and protecting friendly ships. You can use your torpedoes, deck cannon, deck gun, and sniper rifle to destroy the enemy ships, planes, and troops. There is also a puzzle aspect, as you dispatch frogmen to bomb underwater gates. The game throws out the traditional simulation focus of submarine games to focus on arcade style action.
