A poorly secured safehouse will lead to a sudden helicopter event death. Here is how to pick indestructible natural fencing, plumb rain collector barrels directly into sinks, and run generators without suffocating.

📋 Step-by-Step Instructions

Step 1: Scout Safehouses Surrounded by Indestructible Tall Iron Fences

Map-generated tall black metal railings cannot be destroyed by zombie hordes or crawlers. Mansions in Louisville and the gated villas in West Point offer 3-sided indestructible perimeters, meaning you only need to barricade one front gate with double wooden doors.

Step 2: Plumb Rain Collector Barrels to an Indoor Sink for Pure Water

Place a rain collector barrel on the floor or flat roof directly above an indoor sink. Equip a Pipe Wrench in your primary hand, right-click the sink, and click 'Plumb Sink'. The game engine automatically purifies rainwater through the sink faucet, eliminating the need to boil water!

Step 3: Position Generators Outside to Avoid Carbon Monoxide Poisoning

Never place a running electrical generator inside your house, garage, or interior rooms. Generators emit toxic fumes that will rapidly drop your survivor's health to lethal levels. Keep generators outside under an overhanging eave at least 2 tiles away from open bedroom windows.

Step 4: Destroy Ground Stairs and Use Sheet Ropes for Upper-Floor Safety

Use a Sledgehammer to destroy the wooden staircase leading to the second floor. Hang Sheet Ropes from exterior windows. Even if an entire mega-horde breaches the ground floor, they cannot climb sheet ropes, giving you a safe sanctuary.
