Defender II

This is a re-release of the earlier game "Stargate". The name was changed for copyright reasons.

It was released as an improved version of "Defender" because the game didn't have good graphics so had a poor reception since it wasn't as good as the original arcade game.

This game is a two-dimensional side-scrolling shooting game set on the surface of an unnamed planet. The player controls a space ship as it navigates the terrain, flying either to the left or right. A joystick controls the ship's elevation, and five buttons control its horizontal direction and weapons. The object is to destroy alien invaders, while protecting astronauts on the landscape from abduction. Humans that are successfully abducted return as mutants that attack the ship. Defeating the aliens allows the player to progress to the next level.
