It seems someone already interested Solar in the unguarded factories.
Thanks a lot.
At least, make those facilities produce more stuff with slightly less mats, than the amounts by crafting by the same cooldown.
For example: your faction secures the facility, you bring in the brahmin loaded with gunpowder and metal parts.
You feed the mats in the machine to produce 500x5mm JHP rounds. Normally, you would need 30 gunpowders and 10 metal part to produce this amount, but the machine uses the mats more efficient, so it needs only 75% of the mats, so rounded down 22 gunpowders and 7 metal parts. That would also be saved 20minutes mining.
Also, since the work is done by the machine, ammo production doesn't affect your crafting, but perhaps repairing cooldown.
To craft efficiently, you need a operator at the facility and a repairman at the generator, excluding guards.
So it will require a team.
Also: it's an unguarded location, like Sierra or Mariposa, so expect visit, who can either leave or take loot.
So the assaulter will have either your mats or your mass-produced ammo, so there would be even more PvP action than in unguarded mines.
