Space Invaders is a Japanese shooting video game released in 1978 by Taito. It was developed by Tomohiro Nishikado, who was inspired by other media: Breakout, The War of the Worlds, and Star Wars. Though simplistic by contemporary standards, it was one of the forerunners of modern video gaming and helped expand the video game industry from a novelty to a global industry. It was first released as an arcade game and later remade on different platforms; re-releases include ported and updated versions. Ported versions generally feature different graphics and additional gameplay options, including moving defense bunkers, zigzag shots, invisible aliens, and two-player modes.
