Dark Ages (Chinese: 黑暗时代pinyin:Hēi'àn shídài) was the eleventh world in Plants vs. Zombies: All Stars. It was added on January 24, 2016 in the 1.0.91 update.
This world presented a large variety of zombies, however, only a couple of them have unique effects.
Standard[]
Despite different looks, these zombies didn't seem to have any special abilities gameplay-wise, and just dealt melee damage to the right-most plant.
Wizard Zombie[]
Wizard Zombie was the main threat in each level (except for Night 30), as he appeared on each wave in each lane and attacked the right-most plant at a distance each turn. However, he always spawned behind another zombie, so you needed well-upgraded plants like Cypress or Winter Melon in order to deal with Wizard Zombies right away.
Peasant Flag Zombie[]
This zombie only appeared on wave 3 in groups of three or alone. His ability was to summon 2 Wizard Zombies every four turns, starting on turn 1. This zombie could easily swarm the field with dangerous zombies, so stunningplants were necessary.
Imp Wolf[]
Imp Wolf's special skill activated every four turns, which was dealing melee damage to the right-most zombie and restoring dealt damage as a health. This ability wasn't that threating, as Gentle plants would be able to heal all of the dealt damage.
Knight Zombie[]
Knight's special skill activated
every four turns, this zombie would heal a quarter of his own health. This zombie was annoying to deal with, but stunning plants would help dealing with Knight Zombies.
Jester Zombie[]
Jester was an incredibly dangerous zombie, as his special skill activated every four turns, allowing him to dodge all normal attacks and reflect some damage back for two turns. Plants' active abilities still dealt some damage to him and applied all the negative effects.
