Wolf Pack

Under the water is a collection of submarines called The Wolfpack and they destroy all ships that stray into their area. You are the commander of a destroyer and your job is to keep dropping bombs to destroy the subs. The game is a side view single screen game, and you control your ship, left or right, on the top of the screen on the surface of the water. The subs move across the screen, left or right at various depths below and fire torpedoes upwards and these must be avoided or you lose one of seven lives. As you move and bomb, your fuel decreases and if it reaches zero then you lose a life, but a helicopter flies across the screen dropping barrels to increase your fuel. A timer at the bottom of the screen counts from 0 - 100 and when it reaches 100 you move to the next level.
