'''''Space Invaders''''' (スペースインベーダー) is a 1979 milestone arcade game developed by [[Taito]]. The player controls a gun which can move left or right, and needs to destroy waves of aliens (or "invaders") before they reach the ground. ''Space Invaders'' was brought to a variety of home video game consoles and computers, including the [[SG-1000]] in 1985.

Gameplay

Space Invaders was the first fixed shooter game, and it is a progenitor of the shoot-'em-up genre. The player controls a laser turret that can move horizontally and must destroy waves of aliens invaders before they reach the ground. The game has a two-player alternating mode.

Each wave of aliens arranges itself in five rows of eleven invaders. They move left and right as a group, shifting downward (toward the player's turret) each time they reach a screen edge. The goal is to eliminate all of the aliens by shooting them. The aliens have projectile weapons that they occasionally fire at the player's cannon. The laser cannon is partially protected by four stationary defense bunkers, which are gradually destroyed from the top by the aliens (and can also be destroyed from the bottom if the player accidentally fires on one from below). As the invaders are destroyed, the movement of the remaining aliens speeds up.

When an entire wave has been defeated, another wave appears slightly lower than the last. Eventually, the wave spawns with the bottom row right on top of the bunkers. Then the next wave starts from the top of the screen, and subsequent waves are spawned progressively lower again. This loop continues until the game ends.

The player's laser cannon moves with Left or Right and shoots with 1 or 2. The player has three lives and loses one whenever the laser turret is hit by an enemy. However, the game ends immediately if an alien reaches the bottom of the screen.
