Pathologic 3 includes a crafting system that lets you make items to help you survive this strange time traveling journey and find answers about the plague that threatens the town.
I would argue that you could probably complete the game without using the crafting system outside of loading the prototype, but it’s worth learning anyway. Otherwise, you have to rely on finding the items you need in boxes or for sale at vendors.
Where to Craft in Pathologic 3

Before you can craft anything, you need to know where the equipment you use is located. The answer is that there’s a room at Stillwater that has your equipment. If you want an easy method to find Stillwater, it’s where you start the third day when you unlock time travel.
On the first floor of Stillwater, there’s a room with multiple desks. The Bachelor comments that he has his items set up in this room, and you’ll find the setup you need for loading the Prototype, which I certainly needed by this point.
Then, there’s also the setup that you can use to craft other items, such as Taurine, on the desk on the opposite side of the room.
For the crafting set-up, when you interact with it, you can use X to open your recipe book if you’re playing on a keyboard and mouse. Depending on how often you trade with vendors, you might not have many recipes to work with at the beginning, but that’s a fairly easy fix.
Getting New Recipes

It seems that most recipes are purchased from the children around the town. Aside from recipes that you get from the game, such as loading the Prototype, I’ve only found recipes from the children vendors. When you buy their available recipes, they’ll have new ones by the time you show up again, so you definitely want to stop and check out their stock.
If you haven’t done much trading, you’ll also need to make sure you have something to exchange for the recipes, and possibly for ingredients or other items you might need. The children use a bartering system, and I recommend collecting nuts and marbles, both of which you can find in boxes while exploring.

Each item lists a cost, and your own inventory will have costs on each item. Nuts are worth one, but marbles are worth five. This means that you can trade for a recipe, which generally costs eight, with three nuts and one marble.
A lot of the recipes are for items that increase your Apathy or Mania, so you could save up your bartering items to just get the already-made items from the children instead of crafting them yourself in Pathologic 3.
I always enjoy a crafting system in the game, and in this case, it’s the only way that you can keep your Prototype loaded to keep you alive in the plague.
