Iron Maiden is an alternate ability for the Cactus' Tallnut Battlement. The difference between the abilities is that it is smaller, but it is stronger with the health of 500. The only way to obtain this ability is buying sticker packs. Only four Iron Maidens can be placed at a time and the oldest one will be removed if the player attempted to place a fifth one. It takes 30 seconds to recharge.
Encased in iron armor, these Iron Maiden Tallnuts will stare at Zombies with an unmatched intensity. They are very hard to destroy and enjoy getting in the way.
An Iron Maiden has more than or equal to 500 health.

- It can be destroyed immediately if an Engineer jumps on it while riding the Jackhammer.
