*Stargate (also known as Defender II) is a horizontally scrolling shooter released in arcades in 1981 by Williams Electronics. Created by Eugene Jarvis and Larry DeMar, it is a sequel to Defender which was released earlier in the year. It was the first of only three productions from Vid Kidz, an independent development house formed by Jarvis and DeMar.
The Defender II name was used in some home releases, due to legal issues (according to the bonus material for Midway Arcade Treasures, Williams wanted to "make sure they could own the trademark" on the Defender name). The name Defender II has been used on many home ports and game compilation appearances, but not in arcades. The Atari 2600 port was originally sold as Stargate, but was renamed to Defender II for a later re-release.
