The year is 1984. The soviets have created a time machine and stolen sonarbouy technology from the year 2046. Using what little money they had left they trained a crack battalion of ASW pilots capable of instantly finding submarines as soon as they raise their ESM masts or fire a missile. Armed with an seemingly unlimited supply of torpedoes they fly over every ship in the Soviet Navy.
Now you, as the solo suriving NATO ship, must stop the Soviet menace before it is too late! Work with...um command... as you single handly destroy the entire Soviet Navy that should've spent less money on time machines and more money on training Captains to evade torpedoes. Go weapons free and fire at every contact you detect immediately to blast your way throught the campaign because your captain's sixth sense knew it was going to be a bad guy anyway. Steer your torpedoes like a kamikaze pilot for pinpoint accuracy to bring the Soviet bear to its knees.
