Blade Traps will lose durability as they deal damage to enemies or are attacked. If their durability falls too low, they will eventually stop working until they are repaired.

Blade Traps can be repaired with forged steel and mechanical parts by using the secondary action of a stone ax, claw hammer, or nail gun while aiming at a damaged trap. Depending on how much damage the device has sustained, it may require more resources to repair.

Blade Traps are huge, and it can be difficult to find a proper location. On top of this, they function identically to strike an enemy with a blade, meaning that they may deal more or less damage depending on where the blades impact. Because of this, it’s important to think carefully about how you set up these traps.

1. Target Specific Body Parts

It’s tempting to set up a bunch of Blade Traps and let them run. This is still effective, but you can fine-tune your defenses by setting up your traps to strike specific body parts. A headless zombie is a dead zombie, so setting your Blade Traps above the path of your target can turn them into lethal automatic guillotines. Alternatively, you can set them at knee height and have your blades turn sprinting zombies into slow crawlers by slicing off their legs.

2. Overlap Blades

Players can set Blade Traps close enough to one another that the hitboxes of their blades overlap. This effectively doubles the damage of your traps and increases the chances of killing your target before they get through the trap. Placing these devices on either side of a narrow path is a great way to utilize this strategy.

3. Walls and Doors

Blade Traps can be affixed to walls and smooth surfaces to protect your fences and gates. Not only does this punish enemies who get too close to your walls by chopping off their heads, but the blades can be toggled off and on by controlling their flow of power with devices like switches. Since the blades themselves do not take up space or deal damage when not powered, they can safely protect doors in this way without limiting your use of them.
