Navcom 6: The Persian Gulf Defense on the Commodore 64 (also known as Navcom Six: The Gulf Defense) is a 1988 naval action-simulation from Cosmi where you command a warship in the tense waters of the Persian Gulf and choose from three main mission types: Convoy Escort, Patrol, or “Dawn of Death.” Your job is to protect shipping lanes and survive encounters with hostile vessels, aircraft, and mines while avoiding friendly-fire mistakes, blending straightforward mission objectives with fast, arcade-leaning maritime combat.
