Titan, Planet Crete, Omicron Gamma is always a good buy.
For SP I liked to use the SkyBlast B, as I remember you can get it somewhere in the Sigma systems.

Enjoy!

No worries... this seems to be a pretty good map. Right click - view image to see it in full.

Thanks too. I didn't know that in Omicron Beta there was a way to go to Omicron Major & Minor.

The map above isn't correct at all. Like robocop said, Omicron Beta doesn't have a link to Omicron Minor or Major.
Following links are NOT accessable after the story besides these on the map:
Sigma-13 -- Chugoku
Sigma-13 -- Neu-Berlin
New York -- Magellan
Magellan -- Leeds
Leeds -- Dublin
Leeds -- Cambridge
Cambridge -- Omega-3 (JH)
one of the Frankfurt -- Hamburg jump holes
all these not accessable jumpholes/gates are not visible, so they need to be marked with dotted lines. (Maybe just on map in SP).

Omicron Alpha is part of the Hispanian Systems (HI), so it needs to be marked as Outcast System.

If you would like to have a full map of vanilla FL you need to have to add these things + the "second" Omicron Beta (Nomad Lair), "second" Omicron Major where they have the inside of the Hypergate and "second" Omicron Minor with the inside of the Nomad Lair. Or just leave them out. Oh and Freeport 7 - System is missing.

Omicron Beta (SP campaign)!!! 0_o OMG! Here I can't understand why. It's really strange. Why there is two Omicron Beta?

I don't know why they decided to call it Omicron Beta, but they do look very similar. Maybe they represent two portions of a really big but boring rock filled system.... maybe

Anyway, it's used in one of the last episodes where you have to retrieve the Nomad power supply from the Nomad Lair. The player is delivered into the system by the Battleship Osirus, you have to complete your mission in a set time before exiting via the Omicron Minor jump hole and fighting your way back to Planet Toledo.
