Dark Ages (Chinese version)

Dark Age (黑暗时代; pinyin: Hēi'àn shídài) is the sixth world in the Chinese version of Plants vs. Zombies 2.

Like in Ancient Egypt, tombstones appear in Dark Age. However, they now have a much important role since they summon zombies through an ambush called "Necromancy!" and if they are marked with a sun or Plant Food icon reward players with sun (100 sun) and Plant Food when destroyed, respectively. Now occasionally they spawn by themselves and if a grave spawns where there is a plant, that plant and all plants in front or behind it will move forward one column.

Sun does not fall from the sky in Dark Age as it is set during the night, so the player has to use Sun-shroom (it is unlocked for free) in order to get sun, since the other sun-producing plants are locked.

Exclusive to this version, fog returns from the first game as an environmental feature exclusive to some levels. And just like in the first game, Plantern and Blover are the two plants can get rid of it. Plantern can illuminate an area as long as he is alive and Blover blows it away for 15 seconds. Torchwood also illuminates fog, but using him is not recommended because he only works on its tile, even with Plant Food.

Also exclusive to this version there are two new Brain Busters (Oak Archery, and Fright Theater) Five new plants are exclusive to this version (two returning from the first game) and there are three new zombies.

Origins
As its namesake says, Dark Age takes during the tenth century where culture and economy slowly deteriorates mankind that follows the decline of the Roman Empire. Also, the use of Black Magic like Necromancy became the center of usage for evil purposes.
