Surviving the twisted world of 99 Nights in the Forest isn’t just about fighting off the Deer or surviving ambushes from Cultists—it’s also about how cleverly you build your shelter. Among the community’s latest trends, one base idea stands above (and creeps beyond) the rest: the Haunted Hospital.

Blending eerie aesthetics with practical defense, this build transforms the ordinary Hospital structure into a macabre fortress of healing, horror, and creative chaos.

Phase 1: Securing the Foundation (The Real Hospital)

Before your haunted asylum comes to life, you’ll need to secure a strong base and stock essential supplies.

Find the Perfect Hospital Structure

Scattered throughout the forest, these small green-striped Hospitals make ideal bases. They’re sturdy, partially built, and naturally defensible—perfect for players who want a creepy-yet-functional home.

Build and Fortify

  • Perimeter Wall: Use your wood supplies (especially if you’re a Lumberjack) to craft Log Walls. A Level 4 Campfire’s circular outline works great as a placement guide to create a tight defensive perimeter.
  • Defensive Advantage: Cultists are often drawn to Hospitals for their resources, such as Bandages and Scrap Metal. This actually helps your haunted theme—every raid leaves behind new “patients” for your asylum.

Stock Up Essentials

  • Bandages & Medkits – Vital for healing and reviving teammates.
  • Fuel or Coal – Keeps your central Campfire (the XP multiplier) running.
  • Scrap Metal – Found inside Hospitals, used for crafting advanced tools.

Phase 2: Building the Horror Aesthetic (Haunted Elements)

Now comes the fun part—turning your clinical hospital into a nightmare asylum.

Create “Patient” Rooms

Use Log Walls and Beds to craft eerie hospital rooms. For the haunted atmosphere:

  • Decoration of the Dead: Place Cultist or Wolf bodies outside rooms to create a grisly “waiting room.”
  • Premium Room: Add one spacious chamber with the largest bed for your “most important patient.”

The Storage of Secrets

Dedicate one room to your rarest items—Raygun, ammo, and high-tier food from your Crockpot. This is your vault of dark experiments.

The Respawn Chamber

In multiplayer, wall off a small corner and make it your team’s revival zone. It doubles as your “resurrection chamber”—a grimly humorous addition that fits the haunted vibe perfectly.

Phase 3: Embracing the Halloween 2025 Update

The latest Halloween Potion Making Update (October 2025) adds all the spooky tools you need to finish your haunted hospital build.

The Cauldron of Chaos

A new Cauldron near the Crafting Bench lets you brew unpredictable potions.

  • Turning friends into Frogs
