The goal of this game is to destroy the hostile mean submarines, and try to stay alive while doing it. At your disposal, you have a minesweeper and the Swedish marine's latest weapon, the sub-sensitive sinkbomb. Hey, don't laugh, they're pretty sophisticated handled right ! They work like this, if touched by a hard surface, (such as a subshell), they'll explode.This mean, it's up to you to drop them at the right time. The number of currently available sinkbombs is shown in the status bar. The number of sinkbombs is not limited, but you can only have a limited number of sinkbombs in the water. If the bomb number reads zero you'll have to wait until a sinkbomb explode, then a new bomb will be reloaded. The amount of sinkbombs will differ from level to level.
