Dystopian Dimension

Dystopian Dimension is the 13th world in Plants vs. Zombies 2. It was revealed in a trailer on September 27th, 2015 (and the teaser parties started the same day) before Low Tide was released on October 3rd. It takes place in an unknown time. Pepper Corn is the premium plant unlocked for Low Tide.

Gimmick
The main gimmick of the world is acid. It is set at a predetermined column at the start of every level and does not shift. Aci-dates can support plants on acid, but dissolves after one minute. The surprise attack of the world is "Chemical Reaction!", where either Basics, Coneheads, Bucketheads, and Armoreds appear from geysers that rocket from the acid and propel the summoned zombie one tile ahead.

Dialog
Day 1

Crazy Dave: Woah, acid!

Penny: Don't touch it, User Dave. That acid is strong enough to dissolve razor blades.

Crazy Dave: What does it do to plants?

Penny: You do the math.

Day 2

Crazy Dave: Those zombies took that acid pretty well.

Penny: It's also advanced from its previous position. Be wary.

Crazy Dave: But I mean really! They didn't dissolve or anything!

Penny: User Dave...

Crazy Dave: What?

Day 3

Crazy Dave: Woah, Penny! What's that thing floating in the acid?

Penny: That's an Aci-date. It can support plants, but not for long.

Crazy Dave: But how did it get here?

Penny: ...

Penny: Let's just say I know a guy.
