Terraforming is set in a post-apocalyptic world where humanity has fled Earth due to its becoming uninhabitable. The human race travels through space, searching for a suitable planet to terraform into a new home. Along the way, they encounter hostile alien races that must be destroyed to ensure their survival.
The gameplay involves basic side-scrolling shooter elements, including shooting down enemy spaceships, collecting power-ups and health icons, and upgrading main and secondary weapons. The game also features large stage bosses and an immersive atmosphere, courtesy of the renowned special effects artist Syd Mead , who has worked on iconic films such as Star Trek: The Motion Picture, Blade Runner, Aliens, 2010, and Mission Impossible III.
