Air Warrior was a multiplayer on-line air-combat simulator launched by Kesmai in 1988. It was hosted on GEnie and used that service as a server for client software running on a variety of personal computers available in that era. It underwent continual improvement through its decade-long lifetime with Kesmi, appearing on new platforms and host services. Electronic Arts purchased Air Warrior in 1999, and became provider of the game, but it was discontinued in 2001.
