Once Human is an open-world survival game that offers players a robust weapon crafting and customization system. Surviving the apocalypse in this game requires more than just a baseball bat or machete; you’ll need sophisticated weapons like fully automatic submachine guns or light machine guns. To acquire these weapons, you’ll need gunpowder, and to get gunpowder in Once Human, you’ll need acid. This creates an endless cycle of grinding for resources throughout the game.
In the early game, the best way to acquire acid is by slaying enemies like Gnawers, Charred Maniacs, and Lights. Gnawers and Charred Maniacs are common enemies in low-level zones and will drop acid upon death. You can also find junk items in crates, waste bins, and enemies that can be disassembled in a Disassembly Bench to obtain acid.
For those looking for a more passive farming solution, Once Human offers the ability to farm acid passively. This method requires finding polluted zones in the game, such as those near Greywater Camp, Lone Wolf Wastes, and Blackfell. These zones are typically higher level and require tier four and five Memetics to access.
To start farming acid passively, players need to unlock and set up a Water Pump, Reverse Osmosis Purifiers, and Fermentation (Brewing) Barrels in polluted water. The Water Pump feeds into the Reverse Osmosis Purifiers to produce impure acid, which can then be refined using the Fermentation Barrels and purified water to create usable acid for crafting ammunition.
While setting up this passive farming method requires some initial crafting and grinding, it proves to be a worthwhile investment as you progress through the game and have a steady supply of acid for crafting ammunition. By utilizing both active and passive methods of acquiring acid, players can ensure they have the resources needed to survive and thrive in the post-apocalyptic world of Once Human.
