The difference between the abilities is that it is smaller, but it is stronger with the health of 450. The only way to obtain this ability is buying sticker packs. It takes 30 seconds to recharge.
Only four Iron Maidens can be placed at a time and the oldest one will be removed if the player attempts to place a fifth one. Like most of the other alternate abilities, it was introduced in the Garden Variety DLC.
In Garden Warfare 2 it has a Rux exclusive bling variant named the Bling Maiden. Like most of the bling variants however, the Bling Maiden is merely a bejeweled reskin of the default Iron Maiden, and as such functions identically.
Iron Maiden is based off of Wall-nut's Plant Food effect from Plants vs. Zombies 2, where he gets encased in an iron shell which increases his health and the amount of damage he can withstand.
Its name comes from an infamous historical torture device from the 18th century which consists of an iron cabinet just like this Wall-nut's iron plating and spiky interior to torture the victim placed inside. Its name could also be derived from the English heavy metal band of the same name.
Stickerbook description[]
Iron Maiden[]
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.
Bling Maiden[]
This Tallnut is encased in solid bling gold armor! How did a Tallnut even afford such expensive armor though?
Comparison to vanilla counterpart[]
Pros[]
Significantly higher health per ability usage.
Cons[]
Only has one ability charge stored at a time.
Has a smaller hitbox, protecting less area per ability usage.
Strategies[]
With[]
With a greater emphasis on withstanding more damage compared to the Tallnut Battlement, the Iron Maiden specializes at being a tough blockade that zombies will have trouble breaking through. Areas the Iron Maiden excels at includes narrow corridors, as its smaller hitbox size is mitigated when there is no alternative path except chewing through it's elevated health.
While not ideal in a mode like Garden Ops, given the Tallnut Battlement better contains the garden from straggling zombie hits, there is a good place for Iron Maiden in this game mode. If playing with more than one Cacti, having one Cactus use their Tallnut Battlements for backline defense will allow the Iron Maiden to shine as the front-line defensive option.
