Acid is an extremely important material inOnce Human, as it is used to create Gunpowder (and ammunition by extension). Fortunately, there are several ways to quickly obtain Acid inOnce Human, and this guide details two activities that fans who are short on the material should pursue.
This guide also explain how to earn Acid while AFK. That said, it is unlikely that players will be able to accumulate enough of the material using just that passive method, and it should thus be considered as a supplement to more active farming.

Once Human: Acid Farm
Before players set out to farm Acid they may want to take a moment to cook some Preserved Deviated Chops, a food item that increases Acid gain by 50% when defeating Deviants. To gain access to that item, fans must unlock Dishes 3, a Tier 4 Logistics Memetic, and they can cook it in an Electric Stove or Kitchen Set.
Players can purchase Peppercorn Seeds from Lacey, a vendor in the Red Sands' Blackfell. This NPC’s coordinates are 4111, -1475, and fans ofsurvival gamescan use the seeds that she sells to grow Peppercorn for their Preserved Deviated Chops.

Production Facility Events
Production Facilities are machines that players can find in many of the game’s Settlements (marked on the map that is above), and they can be used to initiate events that center around defending the facility. Those events, and the enemies that appear during them, award Acid, and players can initiate them by inserting Blackfell Refinery and Extraction Permits into the machines. For full clarity, those permits can be looted from crates, and fans who have spent some time completingexploration quests inOnce Humanshould definitely have some on hand.
It is highly recommended that players who want to farm Acid throughOnce Human’s Production Facility eventslook to do so in groups. Indeed, while it is possible to complete these events solo, they can be made much easier by enlisting the help of other players.

Kill Deviants
Deviants are an enemy type that has a chance to drop Acid when slain, and players who are looking to amass large quantities of the material can simply spend some time in locations where these foes appear in high numbers. For example,Once Human’s Holt Townis an excellent place to farm Acid, due to the high-density of Deviants that spawn within it, and players can find this Settlement at coordinates 3818, -4451 in Chalk Peak.
To note, Holt Town has a recommended level of 30. While players can definitely defeat the Deviants at this location before reaching that level, they may want to look elsewhere if they are attempting to farm Acid at a much lower level. As examples,Once Human’s Brookham(6595, -4530) and High Banks (5504, -5698) are reasonable options for fans who are looking for lower-level Deviants, though they should not expect to amass Acid as quickly in those locations as they would in Holt Town.

AFK
Players who want to earn some extra Acid while AFK can set up a system that is centered around pumping polluted water, extracting Impure Acid from it, and converting that material into Acid. While this is a fairly slow process, here are the steps that fans who wish to pursue it should take:
