N-Sub — About this game
Pilot a submarine against enemy warships and submarines. Two firing actions serve different targets: vertical torpedoes reach the warships above, while horizontal torpedoes attack enemy submarines. Move into position before choosing a firing direction, and keep away from incoming attacks as the fighting grows more intense. Sinking the fleet of nine warships and its destroyer earns a bonus. The game starts with three submarines, with an extra one awarded after passing 10,000 points.
