Field Combat is a single-player strategy and action game set in a futuristic war environment where players command a warship called the Genesis to navigate through a battlefield, firing missiles and engaging enemy forces. In this game, players control the blue forces, aiming to reach the end of the battlefield while avoiding or destroying enemy units such as helicopters, infantry, and tanks, with the added ability to call reinforcements and absorb enemies into their army. It stands out with its use of Richard Wagner's Ride of the Valkyries as background music, and features unique gameplay elements like summoning reinforcements by pressing specific button combinations and absorbing defeated enemies to strengthen the player's army, along with a UFO enemy that attempts to abduct friendly units and engage in aerial combat.
