Free-to-play multiplayer open-world survival game Once Human is full of otherworldly mysteries, such as a hotel with ghostly volunteers guiding you toward secret notes throughout the town. And itâs the little encounters and special details like these that keep so many of us playing long after launch. Even so, some of these mysteries are more challenging than others, stumping players. For instance, the High Banks Passcode.
How to start Boy Just Wanna Have Fun
High Banks is one of many points of interest youâll discover when stumbling around the horrors of Once Humanâs main plot. Inside is a task thatâll give you some excellent rare resources like Eclipse Cortex and Stellar Planula, and it seems like it should be pretty straightforward. You just need to open a box. But itâs deceptively tricky.
To get to the High Banks Lockbox, you must start the side quest âBoy Just Wanna Have Funâ which will have you roam the town searching for mysterious notes. And before we get started, remember throughout to be wary of Ede. Heâs wandering the main street outside of the hotel youâre looking for, and if youâre not careful, heâll stomp you to death. Heâs mean.
Once youâre inside the hotelâthe tall building in the center of townâhead to the lobby at the front of the building. Sitting inside the planter by reception, there is a single note that begins the task. It tells you to scour the town, looking for notes with numerical clues, and then take them all to the cafe.

In total, there are three clues âhiddenâ around the town. Theyâre all inside of buildings, some of which do contain enemies, so be mindful as you enter, but finding them isnât hardâtheyâll all be marked on your map, so just follow your nose. For the most part, you can skit around the zoneâs most formidable baddies to acquire each of the notes, then take the backstreet to the cafe once you have all three numbers.
Speaking of numbers, those notes provide you with one each: 2, 3, and 5. Youâll need these numbers in the correct order to unlock the lockbox.
The High Banks passcode
Once you finish collecting all three notes, visit the cafe at the entrance to the town for the final note and the lockbox. The note is the last piece of the puzzle, and it reads, âThe third digit is the largest, and the middle number is the smallest. Give it a shot!.â
This should be all the hint you need to deduce the passcode, but to make life easier, itâs 325
Once you unlock the lockbox, youâll receive the following rewards:
x7 Stellar Planula
x1 Eclipse Cortex (Level 2)
x200 Energy Links
x105 Battle Pass EXP
x500 EXP
With another side quest under your belt, a few rare crafting resources, and a mystery solved, itâs time to move on from High Banks to explore the rest of Once Human. Next up, itâs almost time to head north to search for gold ore!
