Chapter 4 takes Grace and Emily into the Courtyard after unlocking the Central Hall door. The environment shifts to outdoor areas with new hazards and a climactic boss fight.

Objectives

  • Navigate the courtyard and maintenance tunnels.
  • Survive the final Shadow Ghost (The Girl) encounter in the Water Treatment Plant.
  • Solve the courtyard gate puzzle.
  • Reunite with Leon.

Step-by-Step Walkthrough

1. Courtyard Exploration

The courtyard is a large outdoor area with multiple paths. Search the garden sheds for ammo and herbs. A few infected are scattered around, but the open space makes them easier to avoid than fight.

2. Maintenance Tunnels

Enter the tunnels beneath the courtyard. The tunnels are narrow and dark, so keep your flashlight ready. You’ll find a Level 2 Wristband upgrade if you missed it earlier, as well as a collectible file near the broken generator.

3. Water Treatment Plant

The Shadow Ghost confronts you in the Water Treatment Plant. This is the final encounter with this boss. The arena has several overhead lamps and flares that you can activate to damage and repel the ghost. Your strategy is:

  • Keep the creature in the light.
  • Activate lamps and flares before the ghost reaches you.
  • Use the S&S M232 to shoot the head when it staggers.
  • Avoid running into dead ends; the arena has two levels of catwalks.

After enough damage, the Shadow Ghost retreats and the path forward opens.

4. Courtyard Gate

Exit the Water Treatment Plant and solve the gate puzzle by aligning the three courtyard statues with the moon, sun, and star symbols. The gate opens, allowing you to proceed to the rendezvous point.

5. Reuniting with Leon

Leon arrives with a vehicle near the gate. This triggers a cutscene and transitions to the next chapter.

Key Tips

  • Use environmental lamps and flares during the Shadow Ghost fight.
  • The Water Treatment Plant has tight corridors; move carefully.
  • Save ammo for the boss; standard infected in the courtyard can be avoided.
  • Explore the garden sheds for optional healing and lore.
