G-LOC: Air Battle is a 1990 air combat arcade game by Sega. The title refers to "G-force induced Loss Of Consciousness".


The game puts the player in a fighter plane, dog fighting other planes. Once the player takes too many hits or the game-timer runs out the game is over. The player earns more time and advances stages by achieving goals that are set each stage. The player initially starts with limited armament which is replenished by completing missions.

Players choose what targets to destroy, like ships, jet fighters, or tanks. Eventually, players will attack bosses such as War Balloon, the Bomber, and the final adversary, an enemy ace who uses the same plane as the player, except with enhanced durability and strength.


The player controls an experimental aircraft (referred as A8M5, but upgraded over time, finally becoming the A8M6) in a mission to eliminate enemy planes. During the game the player is attacked from the front and back. The game is mostly played from a first person perspective; however, once locked onto by an enemy missile, the perspective changes to third person behind the player's plane to allow the player to perform evasive maneuvers. The plane is controlled by joystick and has two weapons: a cannon and missiles. The player can either try to shoot down enemy planes or target them by moving the crosshair over them and launching missiles at targeted planes to destroy them.

The game was released in three arcade cabinet versions: a standard stand-up version, a sit-down version and a deluxe sit-down version: the R-360 cabinet. The R-360 gives the game into a more dynamic feel as the cabinet responds to the pilots action's, somewhat improving on the limited path of plane movement in the standup and sit-down versions.


The game was essentially a sequel to After Burner and After Burner II although not advertised as such. This game was followed by Strike Fighter, a similar game to G-LOC which was also released in Mega-CD as After Burner III. Namco's "Operation Katina" gamemode in Ace Combat 5 features similar gameplay.


G-LOC: Air Battle is one of the video games featuring in the manga titled Cyber Boy, by Nagai Noriaki, Published by Coro Coro Comic and Shogakukan, from 1991 to 1993.

Music Video[edit]

Review score

The game was ported to the Sega Mega Drive, the Sega Master System and the Sega Game Gear. Because the R-360 cabinet made the game more impressive the home computer versions (Commodore 64, Amstrad CPC, ZX Spectrum and Amiga) were named G-LOC R360.

Some ports include certain features not present in the arcade version. The Mega Drive version alternates between first and third-person perspectives at times, the Master System one features bosses, and the Game Gear one employs points that can be used to upgrade the jet.

The Sega Genesis 1990 version of "G-LOC Air Battle" featured packaging art of an over the pilot's shoulder view shoot down by illustrator Marc Ericksen, who had previously created the box art for the 1989 Tengen release of "After Burner".
