High Quality Content by WIKIPEDIA articles! Defender is an arcade video game developed released by Williams Electronics in 1980. A shooting game featuring two-dimensional (2D) graphics, the game is set on a fictional planet where the player must defeat waves of invading aliens while protecting astronauts. Development was led by Eugene Jarvis, a pinball programmer at Williams; Defender was Jarvis`s first video game project, and drew inspiration from Space Invaders and Asteroids. Williams planned to display the game at the Amusement Music Operators Association (AMOA) trade show, though development delays resulted in the team working on the game up until the show started.
