"Dive into the world of retro gaming with Defender II Stargate, an arcade classic released in 1981 by Williams Electronics. Designed by Eugene Jarvis, Larry DeMar, and Bill Aspromonte, this game is the sequel to the popular Defender game. In this action-packed shooter, you pilot a spaceship above a long, mountainous landscape inhabited by humans, which is continuously under the threat of alien invasion. Your mission is twofold: annihilate all alien ships and safeguard the humans from being captured. Equipped with a beam-like weapon and a limited supply of smart bombs and 'Inviso' cloaking energy, you are the last line of defense against the alien onslaught. Stay vigilant, as the top of the screen features a radar-like scanner displaying the positions of all aliens and humans on the landscape. Defender II Stargate is not just a game; it's a nostalgic journey back to the golden age of arcade gaming.
