Code::Lux

Code::Lux is a short, multi-ending post-apocalyptic sci-fi adventure told through a visual novel and a choice-driven journey with roguelite-inspired elements. You follow two travelers as they reach the conclusion of their journey in a world where civilization has collapsed.

A world without power

Commercial nuclear fusion reactors once became a reality, but a world war destroyed them and shut them all down. Without electricity, civilization proved more fragile than expected, and humanity now barely clings to life. People rely on small renewable power plants scattered across the land and on irreproducible technologies known as Relics.

No one has found a way to restart the dormant fusion reactors. A fusion reaction requires fuel to be heated to over 100 million degrees, turned into plasma and confined under extreme pressure. The process needs so much initial energy that it is almost like needing a power plant to start another power plant, and humanity no longer has a way to produce that energy—except through Mitsuha.

Mitsuha and Kai

Mitsuha is a mysterious girl who wants to bring civilization’s light back to the world. Though she appears young, she has extraordinary knowledge across academic fields largely lost in the present age, alongside a strange lack of common sense. She holds administrator-level authority over every government-run system of the former nation and plans to restart the secret last nuclear reactor, forbidden by international treaty.

Kai is a scavenger who roams ruins in search of Relics. He meets Mitsuha in a city and recognizes the value of her abilities. Though he has little interest in her goal, he agrees to work with her to obtain Relics. Practical, cold and ruthless, he rarely speaks of his past, though he shows glimpses of a more human side; there is something he would rather forget.
