Aerial Assault is a horizontal scrolling shooter video game for the Sega Master System and Sega Game Gear.
The player takes the role of a Freedom Fighter who must destroy five targets, including the Vinsk (a flying battleship in the Game Gear version, an ordinary ship in the Master System), the CB-53 Bomber, "El", and two cliff fortresses. During each of the five missions, the player encounters enemy jets, choppers, submarines, jeeps, parachute bombs, and several other enemies which they must destroy. Shooting either the spinning fighters, the small flying helicopters, or the mines on the final mission will earn the player a power-up that allows them to upgrade or downgrade their firepower. There are three difficulty settings: "Easy", "Normal", and "Hard". Players will not be able to complete the game if they select the "Easy" setting.
"Some years ago, an evil militaristic organisation known simply as the N.A.C. developed a huge laser emitter, "EL", which was capable of gradually destroying the ozone layer. This posed an ominous threat to all life on the planet, and cast a shadow of fear stretching to the far corners of the Earth. In the year 1999, the N.A.C. began an all-out offensive against every country in the world. Although initially, each nations Self-Defense forces valiantly stood their ground against the most formidable adversaries, they eventually proved to be no match for the sheer power and size of the enemy. However, just when all seemed lost, the "Freedom Fighter" appeared on the scene. Not officially attached to any one nation, it secretly sped off to clash with the unsuspecting enemy forces."
