G-LOC: Air Battle is a 1990 combat flight simulator arcade video game developed and published by Sega. It is a spin-off of the company's After Burner series. The title refers to "G-force induced Loss Of Consciousness". The game is known for its use of the R360 motion simulator arcade cabinet. The arcade game was a commercial and critical success upon release. 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 in 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.
