Attack The Abyss

The player takes on the role of a submarine operator and must navigate through six stages of varying lengths, whilst avoiding being hit by missiles and colliding with enemy creatures. For defence, the player has torpedoes, with a firing rate limited to one missile visible on the screen at any one time. For every 10,000 points, the player receives an additional submarine. Once all stages have been completed, the game loops and you start all over again.
