*Lanius speed is not specified in-game, and was measured by testing crew speed. The same tests suggest that in-game descriptions for Mantis, Rocks, and Crystals are very slightly wrong in practice, possibly due to tiny delays when crew change directions or pass through doors.

***According to datamining to the game


  • 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 are built around a base value of 100.
  • Mantis and Rockmen have the same potential damage given their health and damage output. (e.g. In a fight a Rockman will last 50% longer, but a Mantis will deal damage 50% faster, meaning they both have the same potential.)
  • A Mantis (Kazaakpleth), Rockman (Ariadne), and Zoltan (Mafan) can be found in Subset's 2018 game, Into the Breach, suggesting the two games are set in the same universe.
