Electric Fences turn a chaotic horde night into something you can actually control. They damage zombies and apply a debuff that buys you precious seconds when you need them most. Here’s how to unlock, craft, place, and maintain them.

Step 1: Unlock the Recipe

Read Electrical Traps magazines until the Electric Fence Post recipe unlocks. You’ll find these scattered around the world in loot containers.

Step 2: Craft the Posts

Head to a Workbench with Forged Iron and Electrical Parts on hand. Costs scale with your Advanced Engineering perk:

• Base cost: 7 Forged Iron, 3 Electrical Parts per post

• At Advanced Engineering Level 4: 5 Forged Iron, 2 Electrical Parts per post

Cost reductions start kicking in at Advanced Engineering Level 3, which matters a lot if you’re planning a large perimeter — the parts savings add up fast across dozens of posts. See our perks guide for the full skill breakdown.

You need a minimum of two posts to form a working fence line.

Step 3: Place and Wire the Fence

1. Set two Electric Fence Posts within range of each other — too far apart and the connection won’t establish.
2. Use the Wire Tool to link the two posts.
3. Run a second wire from one post to a power source (generator or battery bank).

Each fence assembly draws roughly 5 Watts continuously. Factor that into your power budget alongside lights, traps, and anything else running off the same source — undersizing your generator is the most common reason fences stop working mid-horde. For layout ideas, check our base building guide.

Damage and Maintenance

A charged fence applies the Shocked status effect, dealing damage over a few seconds per hit. It’s indiscriminate — a player who touches a live wire takes the same hit as a zombie would, so keep your own crew away from active lines.

Zombies get a brief immunity window right after being shocked, so the fence won’t permanently stunlock a single target — expect some to push through on a second or third hit.

Durability drops with every shock delivered, and once it falls low enough, the fence stops applying the debuff entirely — it’ll still be there, just not doing anything. Repair with Forged Iron and Electrical Parts before that happens, not after. Checking your perimeter every few blood moon cycles is a reasonable habit to get into.

Advanced Layouts

Since each fence segment only connects two posts, you’ll need to chain multiple units to fully encircle a larger base. Layer your fences into choke points that funnel zombies through more than one line, and keep your generator tucked behind a secondary defense — a shocked zombie can draw horde attention straight toward your power source if it’s sitting exposed.

Bottom Line

Electric Fences are one of the more resource-efficient defenses in the game once you’ve got the Advanced Engineering discounts unlocked. The failure points are almost always the same: undersized power, ignored durability, or posts placed too far apart to connect. Get those three right and horde night stops being a scramble.
