Space Invaders is a legendary fixed-shooter arcade game developed by Tomohiro Nishikado and released by Taito in 1978. Widely regarded as one of the most influential video games in history, it helped shape the arcade gaming industry and set the stage for future shooter games. Its simple yet addictive gameplay captivated millions and made it a cultural icon of the late 1970s and early 1980s.
The premise is straightforward: players control a small laser cannon at the bottom of the screen, tasked with defending Earth from descending waves of alien invaders. The aliens march slowly from side to side, moving closer to the player with each pass. If they reach the bottom of the screen, the game is over. The tension builds as the remaining invaders speed up, creating a thrilling challenge as the screen clears.
Players must shoot all the aliens while avoiding their return fire. Occasionally, a mystery UFO appears at the top of the screen, offering bonus points if destroyed. To provide some cover, there are destructible shields that can block enemy shots but also erode from repeated hits. The goal is to survive as long as possible and achieve the highest score.
Space Invaders became revolutionary for its time due to its dynamic difficulty—fewer aliens on screen meant they moved faster, creating natural tension and excitement. It was also among the first games to introduce a sense of urgency with its accelerating pace and ominous sound effects, which grew faster as the invaders advanced.
The game’s success was enormous, leading to a massive boom in arcade gaming worldwide. It inspired countless clones and sequels, influenced pop culture, and even caused a shortage of 100-yen coins in Japan due to its popularity. Today, it remains a timeless classic and a key milestone in gaming history.
