Lightly used game.  Works on the Atari 7800, 7800+ and 2600+.  
 
Take command as the anti-submarine warfare officer aboard a destroyer patrolling the dangerous waters of the South Pacific. Beneath your ship, enemy submarines are on the move, and you have just 90 seconds to destroy as many as possible.
 
Your primary weapon is the depth charge. Up to four depth charges can be launched at once, but careful timing is essential. Use the controller to move the aiming line vertically and set the depth where each charge will explode. Because depth charges are not contact weapons, they will only destroy a submarine if they detonate at the correct depth.
 
Press the controller button to launch a depth charge, and use the alternate button to switch between your destroyer’s two speeds. Line up your shots, judge the timing, and send the enemy fleet to the bottom.
 
Score 2,500 points or more, and your firing window will be extended by an additional 30 seconds.
 
Submarines are arranged in five rows, with deeper targets worth more points:
 
First Row: 10 points
Second Row: 25 points
Third Row: 50 points
Fourth Row: 75 points
Fifth Row: 125 points
