The Arcas Spire Pressure Plate puzzle in Hell Is Us is all about contraptions, pressure plates and levers. You’ll encounter this puzzle in Act 2 of the game when you’re searching for the Keystone of Terror. This will be the fourth puzzle you’ll have to solve in this Act, and it’s a mindboggling one. The goal of this puzzle is to open the chamber doors that lead to the top of the Arcas Spire tower in Senedra Forest. In this guide, we’ll provide the solution to this puzzle as well as the clues you’ll need to solve it in Hell Is Us.
How to Solve the Arcas Spire Puzzle in Hell Is Us
To solve the Arcas Spire Pressure Plate Puzzle in Hell Is Us, you need to pull the levers with the following symbols: Skull, Twin-Headed Snake, and the Tower. Firstly, you need to match the pressure plates that will open the caged contraption in front of the respective symbols and access the lever inside it. The pressure plates will be marked with letters and numbers such as A1, A2, B1, B2 and so on. Here’s the right combination that you require to solve the puzzle and open the chamber doors:
| Symbol | Letter & Number |
| Skull | B2 |
| Twin-Headed Snake | F4 |
| Tower | A1 |
Step on the pressure plates with these letters and numbers on the wall to open the caged contraption in front of the symbols. You’ll find these letters and symbols all around every floor of the chamber. However, stepping on a pressure plate will result in spike traps shooting out from beneath, dealing damage, so carry healing items and avoid stepping on the wrong pressure plate.
Another thing to remember is that the caged contraption gets lifted for only a few seconds, so you must step on the respective pressure plate and hurry down to pull the lever according to its symbols before the caged contraption traps it again. Once you pull down the final lever, a loud rumble will occur, and the three symbols at the top of the main exit door will glow.
You can solve this puzzle in any order, irrespective of which letter and number or which symbol you go for first. If you’re a perfectionist and prefer to find the clues first before solving the puzzle, then you must scan the area with your drone, which will reveal various clues about the lore behind the puzzle and the pressure plates. Solving this puzzle in Hell Is Us will unlock the exit door of the chamber, allowing you to progress through the game.
