From the inlay You are the commander of a frogman team - your task is to destroy the death machines which an enemy government has built in secret locations around the world. They are hidden in underwater caverns protected by dangers such as mines, sharks, jellyfish, strangleweed and poisonous seas squirts. The machines are also protected by an electric barrier - once through this the machines can be defused by shooting the colour coded panels in the correct sequence. The top secret code is given to you at the start of your mission - DON'T FORGET IT! If you succeed, you will be given another, more difficult mission.
