Harbour Attack

In Harbour Attack, you pilot a submarine through three stages to destroy an enemy cargo ship.

Stage 1: Side-view navigation from left to right, avoiding mines and nets while managing air supply and depth. Going too deep, running out of air, or hitting obstacles costs a life.

Stage 2: Another side-view stage where you surface to attack planes and ships, replenishing air while avoiding bombs, torpedoes, and depth charges. An octopus also appears on the C64 version.

Stage 3: First-person view of the enemy harbour, where you guide a torpedo toward a cargo ship’s target while dodging moving barges. You must destroy the ship before your air runs out to complete the mission.
