- A "ghost" race is hidden within the FTL files. According to the events file, they were to have been encountered by the player's crew during the exploration of a wrecked "ghost ship". It was also suspected to be found in the cancelled "Quarantine" sector. The "ghost" race is available with savegame editors and some mods. "Ghosts" have 50 health, do not require oxygen but don't drain oxygen, and have the same look as a human crew but transparent and a yellow glow.
- Health percentages built around base value of 100.
