I haven't played much liberator factions (Still trying to figure out how conquest works via my raider run), so I'm not sure if Liberators have slavery or if there's already an alternative to it. If the first one's the case, that really doesn't make any sense at all. In the case that there isn't some sort of alternative already in place for Liberators, I had one (actually two) ideas that serve as alternatives as "slavery for liberators." ... And before you ask, no, none of them revolve around capturing raiders/gunners/etc and making them "indentured servants". This system that would replace slavery for liberators is called Contracting. The basic gist of it is that you are paying settlers from another settlement to come and work at your settlements for money. Because they're getting paid and not kidnapped, they don't cry for help, and don't turn the whole settlement on you. The other difference with contracted employees is that they can occupy any plot sans military, while slaves can only occupy industrial or agricultural plots. There are two ways I've thought about this could work. The Permanent Method: You build a 'contract' (that functions much like a slave collar, but you don't need to sneak to put it on them), go to another settlement, and instead of "enslave" the option is "offer contract." Once contracted, the settler joins your settlement, where they act identically to a slave would for conquerors. They take reduced food/water (the settlement in question provides half of this), however, they DO in fact take wages. The Temporary Method: You build a 'contract' (again). However, you choose to put a certain amount of caps in the contract. The more caps you put in it, the longer it lasts. You go to a settlement, offer them a contract, and they come and work for your settlement much like a slave would. Here, they're identical to a slave: reduced food and water (again, settlement in question provides half of this), and this time, no wage requirement (you've already paid them in advance). The catch however, is that eventually the contract will run out. You can be notified when this happened and you can track them. You can choose to renew their contract (again, you'll be offered a choice on how much money you want to give them to renew their contract). If you don't, the contract will expire, and the settler will go home.
