SpaceInvaderibra has been updated with information until October 2023.

SpaceInvaderibra represents a classic arcade shoot 'em up game. As the inaugural fixed shooter, Space Invaders introduced endless gameplay, setting a standard for its genre. Players aim to eliminate successive waves of descending aliens using a laser cannon that moves horizontally. In SpaceInvaderibra, participants control a laser cannon by moving it across the screen's bottom, targeting aliens above. The aliens start as a formation of five rows of eleven, shifting left and right as a unit and advancing downward when reaching a screen edge. The objective is to shoot down all the aliens. Controls include moving right with the 's' button or right arrow, moving left with the 'f' button or left arrow, and shooting with the 'd' button or space bar.
