Dark Ages


 * For the Chinese version, see Dark Ages (Chinese version).

Dark Ages is the seventh world in Plants vs. Zombies 2. It is the first world in Plants vs. Zombies 2 to be in a night time setting, similar to Night from Plants vs. Zombies. The mushrooms make their debut here.

As it namesake says, Dark Ages 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.

Like in Ancient Egypt, tombstones appear in Dark Ages. However, they can now occasionally spawn by themselves and summon zombies through an ambush called "Necromancy!". Certain tombstones marked with a sun or Plant Food icon reward players with 100 sun and one Plant Food when destroyed respectively. Sun does not fall from the sky in Dark Ages as it is set during the night. If a grave spawns where there is a plant, that plant and all plants in front or behind it will move forward one column. Sunflowers and Twin Sunflowers still do produce Sun in these levels, but it is still recommended to use Sun-shrooms or Gold Blooms due to their lower costs.

Game description
''Bring out your undead to the year 948! Harvest mushrooms in the dark of knight and get medieval on zombies from the days of yore!''

Order of events
The player uses a World Key, giving them access to the Dark Ages, when the player defeats Night 9's wave, a medieval scroll is shown, saying "By decree of Lord Zomboss: Please leave thoust brain on thine stoop". On the tenth night, Dr. Zomboss writes a note before the huge wave attacks. The wave with the Dark Ages Gargantuar is defeated, leaving a World Key behind. On the twentieth night, Zomboss reveals that Plant Food is made out of zombies before attacking the player in his Zombot Dark Dragon, when the Zombot is destroyed, Penny reveals that Plant Food contains no zombies or zombie byproducts, Zomboss then retreats.

Levels
There is a total of 19 levels and 1 boss battle to play as well as introducing five new plants (four were returned) and eleven new zombies.

Difficulty
Hence its four Jalapeno difficulty, this world is a hard world. It contains nine somewhat hard-hard nights: 6, 7, 9, 10, 11, 15, 16, 19, 20, and three very hard nights: 13, 17, and 18. Using Twin Sunflower as the only sun producing plant in an level makes sun production impossible in an level, even with boosts, due to its cost being too high. Thus, it is much harder than the previous world, Far Future.
 * Easiest level: Dark Ages - Night 1
 * Hardest level: Dark Ages - Night 18

Main levels
+ The plant next to it is boosted, even if the player does not have it boosted.

Dark Alchemy
Dark Alchemy is Dark Ages's exclusive Brain Buster. These levels layouts are exactly the same as the normal levels, but potions will rise from the ground over time and boost zombies if they're stepped on. The potions will bring different effects to the zombies such as increasing their health and speed. While they are being vested by speed and strength boost, the zombies also grow big.

Arthur's Challenge
Arthur's Challenge is Dark Ages' Endless Zone. Grave Buster is exclusive to this and Pyramid of Doom. This Endless Zone is very difficult as Winter Melons and other strong plants will be useless against Gargantuars because of Jester Zombies. The former combined with Zombie Kings, Knight Zombies, and Wizard Zombies further add to this Endless Zone's difficulty.

Zombot Dark Dragon
Zombot Dark Dragon is the boss of Dark Ages and is encountered at the final level. It can shoot fireballs that can hatch Imp Dragon Zombies and those fireballs can also damage plants and zombies. The fireballs also create scorched tiles that cannot be planted on. Fortunately, they only last for a few seconds.
