A Nocturne is a FitD game inspired by the dark cosmological scifi of Alistair Reynolds, among other sources.  You're a crew of exiles, bad people from the level of ordinary criminals up through planet-killing war criminals and ontological threats to reality.  You have a spitter ship, a massive slower-than-light craft of forgotten and warped assets.  Can you score enough profit to keep the lights on before a system collapses into chaos and you have to flee into parsecs of distance and decades of cold sleep?

A Nocturne shines in  the character playbooks. They feel perfectly fit to the implied fiction of the setting, and the special abilities are notably potent.  You're not some guttersnipe with a knife, you're an ancient survivor of the interstellar void and you have powers beyond human ken at your command.

The rest of the game makes some minor tweaks to the BitD core. Scale goes way up, and so does the Profit that you'll need to operate your ship.  One thing I liked was the Vice mechanic has been replaced by an Outlet, which lets you take a downtime action to externalize stress and move it from your sheet and onto the ship, which becomes increasingly haunted and hostile the worse things get. Trauma can be removed with long term projects or in a crisis, a score.
