Talju might be one of the smallest zones in Hell Is Us, but that doesn’t mean it’s lacking in optional objectives, such as the “Supply Chain” mystery. In truth, this one might be the hardest in the whole area, and one that is time-gated, meaning that you won’t be able to complete the mystery until certain things happen in the area. So, if you want to see exactly how to complete “Supply Chain” in Hell Is Us, here’s a quick guide to help you.
‘Supply Chain’ Mystery Walkthrough
The entirety of “Supply Chain” happens in Talju, which is one of the Act 2 zones of Hell Is Us. Your visit will be a short one, and you won’t likely have to return for further objectives, so it is better to finish everything up here before moving to another place.
To get the breadcrumb that will kickstart this mystery, you’ll need to find the train tracks and follow them almost until the end, where you locate a train stop and a corpse below it. There, you’ll get a Diary, which is the first thing that will lead you to this optional quest.

Once you get the Diary- Crazy Week, keep exploring the town and head toward the Playground. You should already have the town’s map, as it is the first item you obtain in Tulja. When you approach this location, look for a pedestrian bridge, defeat the enemy, and interact with the corpse.

You will obtain the Pharmacy Key, which, sadly, doesn’t have a use right now, and here is where the time-gating part begins. But don’t worry, it won’t take long for you to solve the mystery.

Keep progressing through the story until everyone leaves Talju. Be careful, asย this is a point of no return for this zone. Once everyone gets in the truck and leaves, a few objectives will become unavailable, except for “Supply Chain” and a couple of others.
In any case, after the truck drives away, you’ll now be able to use the pharmacy key on the back door. Enter the pharmacy, loot everything around it, unlock the front door, and return to the terminal.
Here, you’ll need to figure out the passcode, which is a bit hard to crack, as there aren’t a lot of clues around. But guess what? Here’s where the diary comes into play. According to the person who wrote the diary, something strange happened with the pharmacy’s clock. They mentioned how “the clock broke down and the hands stopped exactly in between all the numbers in our computer password.” That’s your clue.

After reading that, look at the clock on the wall next to the terminal, and you’ll notice how the hand stopped between 9 and 10, and then 1 and 2. Meaning that your code is 91012.

Input the code into the terminal and read the file inside to complete the mystery. Just like others, there aren’t any combat rewards here or things that will affect your gameplay, but they will help you check another mystery off your list and work toward that 100% completion rate.
