It had colored glass over the screen that would change the colors of the aliens as they came closer to the cannon. The cabinet had a joystick to move the cannon left or right and a button to fire. The little alien invaders became instantly recognizable. Even the Jaws-like music during the invasion became an instant classic. Since then several ports and clones have come about, but none were able to capture the same magic until Space Invaders Extreme came out on the PSP and DS. The surprising hit has now garnered a sequel with Space Invaders Extreme 2."
