Hawk Storm (UK) (1990) - Amstrad CPC - Shooter, Sci-Fi

Hawk Storm is a brave warrior living on the planet Edos, and its citizens look up to him for survival. Edos has only one source of energy: the giant capacitoid crystals, capable of storing energy by day and regenerate that energy during the icy cold nights. Having realized this, the evil Nevik warriors decided to steal all but two of these crystals, making it impossible to sustain normal life on the planet. As a result, all of the people are forced to go in a Life Suspension Program, except Hawk, who must recover all thirty-two stolen crystals if Edos is to survive.
