Space Invaders

About

Released in 1999 by Z-Axis across PlayStation, PlayStation 3, PlayStation Portable, Nintendo 64, Dreamcast, and PC, Space Invaders is a fixed shooter in which the player operates a laser cannon that slides horizontally along the bottom of the screen. The objective is to eliminate five rows of eleven aliens — though some versions alter this arrangement — that march back and forth in formation while gradually descending toward the player's position. Shooting an alien clears it from the field and awards points. As the alien population thins, the remaining enemies accelerate their movements and the game's music quickens to match, raising the tension as fewer targets remain. The core loop centers on managing this escalating pace while positioning the cannon accurately enough to clear each wave before the invaders reach the bottom of the screen.
