1-Gardens to make the healing liquid. Which is in stims. To harvest you could put it through some kind of machine to squeeze out the liquid so u can then put it in stims or a industrial liquid storing container. Something else that would go with this Would be. Water you obtain water by either buying it or via. Filtration system which you have to repair using parts you find around the radius. Once you have repaired the system you have to find/buy gas and you have to get a bottle or a water tank and go to blood water and put in the system which it will filter the water for your garden so you can grow plants for heals and food a bonus would be you have to drink water.
1.5 instead of liquid for meds so it can be lore accurate. The plants could also produce a powder you can put in the stims
2-Ability to make ammo. First you would have to get gun powder which their would be multiple types :FMJ,AP,TR, Or u could use ingredients to mix with plain gunpowder to make the other type's of gunpowder.
