Instructions: The goal is to shoot the Aliens before they descend to the ground. They shoot back so you must avoid getting hit by moving and using shields. For bonus points, shoot spaceships that fly by.

Controls: Use left and right arrow keys to move horizontally. Press the space bar to shoot.

Note on the Arcade game: Created by Tomohiro Nishikado, Space Invaders was one of the earliest shooting games that helped spawn the global video game industry. Its release in Japan caused a temporary shortage of 100-yen coins. Guinness Book of World Records ranks Space Invaders as the top arcade game of all time.

Flash Game Creator: Paul Neave, based on the arcade game released by Taito in 1978 and later licensed by Atari for release in the United States.
