Space Invaders is a famous video game. 

Space Invaders is a very famous video game. 

In the game, you control a laser cannon. You move it side to side at the bottom. Your goal is to shoot the aliens. They move in rows and slowly come down. If they reach the bottom, the game ends. You can also hide behind green blocks for safety. 
One cool thing happens as you play. As you shoot more aliens, the game speeds up. The music gets faster, too! This happened because the computer could work faster with fewer aliens on the screen. Nishikado decided to keep this feature. It made the game more exciting. This game helped start the golden age of arcade games. It even helped make Japan a leader in video games.
Space Invaders is one of the most famous video games ever made. 

Playing the game is a fast and exciting experience. You control a laser cannon called a "Laser Base." You move it horizontally across the bottom of the screen. Your job is to shoot the alien invaders overhead. The aliens move in rows and shift downward each time they reach an edge. They even try to destroy your cannon by firing projectiles back at you. You can use stationary defense bunkers to help protect your cannon. 
Japanese designer Tomohiro Nishikado created the game in 1978. He spent a whole year working on the design and the hardware. He wanted to create a game with more tension than older games. He drew ideas from science fiction stories like "The War of the Worlds." He also looked at movies like "Star Wars" for inspiration. He even designed the custom computer parts needed to run the game. He worked alone to keep the costs very low. 
Many technical details make this game special. Nishikado used an Intel 8080 microprocessor to show better graphics. 

Space Invaders changed how people play games at home and in arcades. The 1980 version for the Atari 2600 console was a huge success. It was the first "killer app," which means it helped many people buy the console. The pixelated alien has become a famous icon in pop culture. Today, the game has many sequels and remakes. It has even inspired many new pieces of art and music.

Space Invaders was a massive commercial success. By 1982, it had grossed billions of dollars in inflation-adjusted terms. 
A fascinating technical detail emerged during development. Nishikado discovered that the processor could render animation frames faster when fewer aliens were on screen. This caused the aliens and the music to speed up automatically as they were defeated. Rather than fixing this, he kept it as a gameplay mechanic. This unintended feature added to the game's difficulty and excitement. Today, the pixelated alien remains a major pop culture icon. The game has inspired countless sequels, remakes, and various works of art and music.
