The archetypal side-scrolling shooter.
As Captain of the Spaceship Defender, the players' mission was to destroy the alien force and save the Humanoids. When Humanoids were abducted, the Lander had to be destroyed and the falling Humanoid catched before safely returning him to the city below.
Defender was the first dual-window-display game. It shows the map of the oncoming territory smaller in the image, warning of the enemy forces that are ahead. This helped the games to prepare for the next encounter.
