Azriel convinces the Boryokudan to give him the location of Center 7 in exchange for Azriel retrieving a missing Juice supply to the Boryokudan, which is eventually revealed to have been stolen by a woman named Sayuri, who reveals she had escaped from Center 7 one year previously. His information is tentative, pointing to a secret facility, Center 7, in a nearby nebula where Daniel may have been taken. Azriel comes to aid Matthius Howard, a friend of Azriel's from the previous war who is wanted by the Boryokudan and who claims to have information on Daniel's location. While searching the planet of Barracus, Azriel is aided by his friend and pilot Kane Harris, who maintains their spacecraft in orbit. One is Azriel Odin, an assassin now turned to a law enforcer who is seeking to get any information about his brother Daniel. The game initially follows two characters. Though peace has come, the war left a power void, and the mafia-like Boryokudan crime syndicate controls much of the system, using its control of a drug called 'Juice'. Gemini Rue takes place in the 23rd century within the 'Gemini System', a star system recently declared independent from the Taurus and Pleaidas System through the war ten years prior to the beginning of the game. At certain times, the player is able to switch between two characters located in different areas of the game's world proceeding through each of these stories separately until reaching a common story.

The player is equipped with a communicator device to call other characters and look up information via a limited text interface. The game also contains a minor gunplay mechanic. Gameplay consists of exploration of the local environment, interactions with characters, and puzzle solving. Later in the game they also control an additional character named Sayuri. The player alternates control between two characters, Azriel and Delta-Six, at different intervals throughout the story.

A port for iOS devices was released on April 11, 2013. The game uses a point and click interface to interact with the environment to solve puzzles and communicate with characters. Gemini Rue is a cyberpunk graphic adventure game made by Joshua Nuernberger, and published by Wadjet Eye Games.
