Our take on The Luminous Underground

Its text-only format concentrates the experience on written choices and story breadth, but gives up graphics and sound effects. Players looking for visual exploration or audiovisual presentation will find the format restrictive.

What is The Luminous Underground?

Run a small spirit-dissipation company in Barrington, an old city filled with specters, daemons, and other supernatural threats.

The story takes place in a haunted subway system that includes crystalline forests, a portal to another realm, robots, giants, and a giant robot daemon. Choices control this 660,000-word, entirely text-based interactive novel, with no graphics or sound effects. Build a team, develop magical skills, investigate disappearances, uncover possible corporate corruption, and decide whether to cooperate with other outfits or work independently. The protagonist can be male, female, or nonbinary, with gay, straight, aromantic, or asexual identity options. Scenarios include helping time travelers, protecting the mayor, and rescuing a missing crew.
