You didn’t crash-land alone, and you don’t have to build the factory alone either. Not Alone adds human teammates with different roles (miners, builders, carriers, and soldiers) to help build your factory. Check the in-game Factoriopedia if you're confused. Note that this mod is in very early alpha and will be updated frequently with bug fixes and new features so check for updated versions often! Make sure to check out the YouTube channel @not-alone.factorio for video updates on new features.
