Earthlight

Earthlight is a scrolling shooter video game published for the ZX Spectrum in 1988 by Firebird Software. It was written by Pete Cooke.

The player takes the role of an alien explorer from the star-system of Arcturus, called Slaatn, who has been drawn off-course by a beam of energy from Earth and has had to make a landing on the moon. Slaatn must neutralise the box-like transmitters and thus eliminate the force field.

Earthlight is a shooter featuring parallax scrolling and shadow effects, a novelty for the Spectrum.
