How to open the Sewers gate (water level puzzle)

The wheel-and-water-level puzzle that gates progress out of the Slums into the Sewers.

How to open the Sewers gate

At the end of the Slums chapter, the path forward is blocked by a metal gate over a flooded passage. To open it, you need to drain the water using two wheels and a valve.

Steps

  1. Find the first wheel — it's on a pipe to the left of the gate, at cat height. Press triangle to turn it. You'll hear water start draining.
  2. Find the second wheel — climb up the pipes on the right side of the room. Wheel is on a platform near the ceiling. Turn it.
  3. The water drops, exposing a valve below the gate. Drop down and press triangle on the valve.
  4. The gate raises. Walk through.

If you hear no water sound after a wheel turn, you turned it the wrong direction — turn it back. The wheels lock once correctly set.

If stuck: the second wheel is genuinely hard to spot. It's behind a horizontal pipe — you have to walk past it on the platform and turn around.
