Metroid Prime II: Echoes - Gamecube

The game takes place on the planet Aether, where a technologically advanced race of moth-like creatures, the Luminoth, have been harbouring and protecting the natural energy of the planet, called the Light of Aether. A Leviathan struck the planet, dividing the planet and its energy into two dimensions; light and dark. This new dark world is home to the Ing, a race of dark, semi-liquid creatures that can possess the bodies of the living, the dead, and the artificially intelligent. They can also have bodies of their own. The Ing and Luminoth are locked in a bitter struggle for survival, as Aether's planetary energy cannot support both worlds. The Ing so far have been the victors, taking the energy from three of Aether's four temples, leaving only the main energy controller to harbor any of the Light of Aether. Should the Ing steal this last piece of energy, Light Aether will be destroyed.
