Cosmic Guerilla is a fixed shooter arcade video game developed by Universal and released 1979.

The player takes control of a laser cannon at the bottom of the screen whose movement is limited to left and right, and must fire at the aliens above.

[1] In contrast to Space Invaders the aliens are arranged in a single vertical line on each side of the screen,[2] with their movement being towards the centre, one or more at a time, in an attempt to capture and remove the player's shields.

[3] Cosmic Guerilla was invariably compared to Space Invaders, though Sinclair User described it as the "next step up", with its different scenarios and object arrangement.

[3] The game was generally well received, and described variously as "incredibly addictive" and "very playable",[2] and "highly recommended".
