Space Invaders
Introduction
Space Invaders was developed and released by Taito in 1978, designed by Tomohiro Nishikado, who reportedly spent close to a year building both the game and the custom hardware needed to run it. Players control a small cannon at the bottom of the screen, moving left and right to shoot down descending rows of alien invaders while dodging their return fire, taking cover behind a set of destructible shields that slowly wear away as the battle continues. As the alien formation thins out, the remaining invaders move faster and more erratically, creating mounting tension that became a defining feature of the shooting genre. Space Invaders is widely credited as one of the earliest and most influential shooting games, helping transform the arcade business from a niche curiosity into a mainstream cultural force; its overwhelming popularity in Japan is often linked to a genuine shortage of 100-yen coins at the time. Its formula of escalating difficulty and fixed-position shooting laid the groundwork for the entire shoot ’em up genre that followed in the decades after its release.
