The sector map in FTL is a multi-pathed "tree" with each leaf colored to represent its type:

  • Green: Civilian sectors
  • Red: Hostile sectors
  • Purple: Nebula sectors

Sector colors appear to be generated at the beginning of the game, and they remain the same throughout the course of the current game. However, each sector type has a number of sub-types available. For example, a "Civilian" sector can appear as one of the following:

  • Civilian sector
  • Engi controlled sector
  • Engi homeworlds
  • Zoltan controlled sector
  • Zoltan homeworlds

Are these sub-types also selected at the very beginning of the game, or are they chosen when the player moves from one sector to the next? Would multiple play-throughs of a single save game result in the same possible sectors every time?

Yes - sector type is determined at the start of the game

The sector layout, sector type and sector subtype is determined at the start of the game, so save scumming will not result in getting different sector sub types.

I tested this by doing the following

  • Start the game
  • Proceed to the end of the sector
  • Save and exit
  • Go to My Documents\My Games\fasterthanlight and make a copy of continue.sav
  • Start the game
  • Go to the next sector and check sector type
  • Exit the game
  • Restore continue.sav
  • Start the game
  • Go to the next sector and check sector type

So, I got to the end of the sector, saved and exited and backed up my game file as mentioned above before clicking "Next Sector":

I then restarted the game and clicked "Next Sector" to progress;

As you can see, the sector types shown that I am able to progress to are "Uncharted" and "Civilian". I selected "Civilian" to see if this would then generate one of the subtypes but just got a plain "Civilian" zone:

I exited the game and restored my backup save and tried again, selected the "Civilian" sector and again found that this was just a plain Civilian sector.

I repeated this process two more times to rule out the possibility of any random luck generating the same sector types repeatedly. With this in mind, it looks like the sector types are generated at the start of the game.

  • Well, there goes my attempt at unlocking the Crystal Cruiser. I was able to complete the first two steps of that quest, but I didn't get a Rock Homeworld sector in my map. :( Commented Feb 13, 2014 at 14:33
  • Great answer! @JonahBishop There are some pretty good tutorials on the Steam FTL forums for that if you don't mind restart scumming. I got the crystal cruiser in 2-3 hours using one method.
