Preload
From Starsonata Wiki
The Preload galaxies were the starting point for new characters in Star Sonata. It has since been replaced with the Nexus.
Newcomers used to begin at Rat Preload, where they learned the basics of piloting their ship and fighting enemies. After jumping through the wormhole, they arrived in Commerce Preload, which teached the basics of trading, mining and making money. There were also some missions to undertake at the station there. Once everything had been learned or new characters felt ready to leave the Preload galaxies, jumping through the second wormhole had lead them into The Nexus, where advanced features of the game are taught, and onward into the main universe of Star Sonata.
The rats and commerce preloads are outdated. The new starter galaxies are EarthForce Outpost and EarthForce Trading Outpost.
