Space Invaders is a 1978 shoot 'em up video game developed and published by Taito for arcades. It was released in Japan in April 1978, and released overseas by Midway Manufacturing later that year. Space Invaders was the first video game with endless gameplay and the first fixed shooter, setting the template for the genre. The goal is to defeat waves of descending aliens with a horizontally moving laser cannon to earn as many points as possible.
Designer Tomohiro Nishikado drew inspiration from video games such as Gun Fight and Breakout, electro-mechanical target shooting games, and science fiction narratives such as the novel The War of the Worlds, the anime Space Battleship Yamato, and the film Star Wars. To complete development, he had to design custom hardware and development tools to use the features in microprocessor technology, which was new to him. Upon release, Space Invaders quickly became a commercial success worldwide; by 1982, it had grossed $3.8 billion ($10 billion in 2024-adjusted terms), with a net profit of $450 million ($1.2 billion in 2024 terms). This made it the best-selling video game and highest-grossing entertainment product at the time, and the highest-grossing video game yet.
Space Invaders is considered one of the most influential and greatest video games ever, having ushered in the golden age of arcade video games and Japan's long-lasting global success in the video games industry. It inspired several prolific game designers to join the industry and influenced numerous games across different genres. The game has been ported and re-released in various forms, including the 1980 Atari 2600 version, which quadrupled sales of the Atari 2600 console and became the first killer app for video game consoles. The pixelated enemy alien has become a pop culture icon, often representing video games as a whole. The game has spawned dozens of sequels and remakes, been the inspiration for numerous pieces of art and music, been parodied across media, and been the focus of several pieces of legislation to limit access to video games.
Gameplay
Space Invaders is a fixed shooter in which the player moves a laser cannon, referred to as a "Laser Base", horizontally across the bottom of the screen and fires at a group of the titular alien invaders overhead. The invaders begin as five rows of eleven—the amount differs in some versions—that move left and right as a group, advancing on the shooter by shifting downward each time they reach a screen edge. The goal is to eliminate all the invaders by shooting them. Regardless of how many game lives remaining the player has, the game ends if the aliens reach the bottom of the screen.
The aliens attempt to destroy the player's cannon by firing projectiles. The laser cannon is partially protected by stationary defense bunkers that are gradually destroyed from above by the invaders; the bottom will be destroyed if the player fires when beneath one. As the invaders are defeated, their movement, as well as the accompanying music, speeds up. Defeating all the aliens brings another wave that starts lower, a loop that can continue endlessly. A special "mystery ship" will occasionally move across the top of the screen and award bonus points if destroyed.
