This mod adds new defensive structures called barbed-wires. After being placed down, any enemy that walks on them is damaged and slowed.
You can upgrade the standard barbed-wire with to be:
- Reinforced: More health and damage
- Slowing: Increases the slowdown effect
- Conductive: Can be charged to deal electric damage
