Guide to complete the Stacked Car Puzzle in Once Human

To initiate the Stacked Car Puzzle in Once Human, first, you need to find one on the open map. You can potentially find the puzzle at the following coordinates:

Coordinates

• 5671, -3859
• 5903, -5931

Once you reach these coordinates, simply look around to find the cars. It shouldn't be too difficult to spot because they are quite tall. Once you find a car stack, go near it and interact with the Monitoring Equipment you will find next to it. This will initiate the puzzle.

The Stacked Cars Puzzle is more of a challenge than a puzzle. Once you have interacted with the monitoring device, you will need to start climbing the cars. You will find red lights indicating the best path for reaching the top. The hitboxes of the cars are quite clunky and weird, so you may need to take some creative paths to reach the top.

This challenge is time-sensitive, so you will have to reach the top in time or you will fail. If it happens, simply go back down and interact with the monitoring device again to re-initiate the puzzle. It may take a couple of attempts, but eventually, you will reach the top of the car stack. Once there, touch the red light and a reward chest will spawn. Interact with both the puzzles to receive the following rewards:

• Fastened Mini Reflex Sight
• Recon Combat Optic
