Navigate the Arcas Spire puzzle in Hell is Us with our comprehensive walkthrough. Learn how to activate pressure plates and levers to unlock doors and find hidden rewards.
The Arcas Spire in Hell is Us features a pressure plate puzzle with optional doors and a main gate. The optional doors are for 'Moon', 'Eye', and 'Flame', while the main gate requires activating 'Skull', 'Snake', and 'Tower'. As you explore, you'll find letters and numbers on signs, some behind obstacles or between cells. Standing on pressure plates causes significant damage.
Activating pressure plates allows you to run levers in cages, which then open various doors.

- 2Tower Puzzle Piece: Pressure Plate A1. Go up stairs, turn left, go down the prison hallway. Find a cell with a hidden tunnel to bypass rubble. Go through to find A1. Activate it, then drop down. Reward: Main Door.
- 3Flame Puzzle Piece: Pressure Plate A4. Go up stairs, look ahead at the flame door. The left is the pressure plate. It unlocks adjacent prison cells, potentially swarming you with Hollow Walkers. Stagger their deaths to heal, then stand on the plate again to reset the timer. Kill remaining enemies to heal, then activate the Flame lever. Reward: Research item - Marked Map of Hadea.

To the right is an open cell with a ladder. Climb it to reach a corpse with the item.
