The game is set in the San Francisco Bay Area. Notable landmarks include the Golden Gate Bridge, San Francisco – Oakland Bay Bridge and Alcatraz Island. The Electronic Arts headquarters in San Mateo are also depicted.
The player can also take off and land from the following airfields:
Finally, when selecting a location to start a free flight, pressing the  key starts the player on uninhabited ground far away from the main game area. This is in fact supposed to be Edwards Air Force Base, a location that was not actually implemented in the final game.
Only air-to-air weapons are available, and are limited to AIM-9 Sidewinder missiles, AIM-120 AMRAAM missiles, and the M61 Vulcan gatling gun (500 rounds). Chaff and flares are available for defense against enemy missiles.
An unidentified aircraft has been spotted heading towards San Francisco. The goal is to take off, obtain visual confirmation, and return to base. The briefing states "Do not fire unless fired upon".
A hostile aircraft is threatening Air Force One. The player must ensure that the President reaches San Francisco safely, shooting down the enemy MiG if necessary.
Two F-16s with secret ECM equipment have been stolen by defecting pilots. Two MiGs are providing air support. The player must attempt to force them to return, but if they refuse, the F-16s must be destroyed.
An F/A-18 has been shot down, and the pilot has bailed out near the Farillon Islands. In order to survive he needs a rescue pod dropped from the player's aircraft (by pressing Shift+F). Two or three hostile enemy aircraft are in the area.
A cruise missile is heading towards San Francisco and must be destroyed. The difficulty here is the missile's high speed, low altitude (200 feet) and short time available until impact.
Hostilities have broken out, and a submersible aircraft carrier is in the area. Multiple enemy aircraft and the carrier must all be destroyed.
This final mission has become the subject of debate among gamers because it is apparently impossible to sink the enemy carrier sub. Programmer Bob Dinnerman states that it is possible, but that the carrier does not actually blow up if it is deemed destroyed.
If your Amiga had more than 512KB RAM installed, you could hear a theme song from Dave Warhol which resembles the Top Gun Anthem from Harold Faltermeyer and Steve Stevens. This was at the request of programmer/designer Robert "Bob" Dinnerman, who asked sound effects engineer Dave Warhol to convey the atmosphere of that particular song from the movie Top Gun.
Placed as an Easter egg, you can find the Electronic Arts Headquarters on the San Francisco map.
