Synopsis Darker has the player assume the role of Tolly, a civilian shuttle pilot in the city of Delphi, the only city situated on the dark side of a planet in synchronous rotation around the local star . The player must defend Delphi from the Halons, inhabitants of the planet s light side, who are invading Delphi. The game takes place over a number of missions on the planet s surface and in underground tunnels. Story Darker s story is revealed over the course of the game as information gathered by reconnaissance . The people of Delphi are not Militarization militarised , having never had reason for military action, and so technology for combating the Halon menace is developed over the course of the game. The Halon people are revealed to be invading in order to expand their cities away from the light side, which they have polluted beyond the point where it can sustain life. Eventually Tolly pilots a Halon craft to the light side of the planet, where he destroys the Halon aircraft factory factories . Gameplay The bulk of the game is played piloting a Caero shuttle. Due to the scarcity of energy on the dark side of the planet, power to the shuttle is transmitted wirelessly through a network of pylons situated on a regular grid across the city.

As losses increased during the course of the conflict, studies were initiated to find a way to reduce the loss rates, with research that continued after the war. The research analysis revealed that fuel fires and explosions accounted for 50 of the losses, and that half of these were attributable to fuel explosions in voids or so called dry bays.
