Hellfire Depths

Hellfire Depths is the 15th world in Plants vs Zombies 2: It's About Time (GMXX Version). It is the final world before Modern Day, and has a total of 29 levels, 9 plants, and 2 upgrades. It can be unlocked with the World Key from Jurassic Marsh Day 8. It takes place in the year 666, and upon arriving there, Crazy Dave and Penny fall through a hole into the depths of hell. After Day 8, The Player receives the Final Key, which is used to unlock Modern Day. The world is kind of like a reverse Frostbite Caves, the main gimmick being Fire Plumes that can't be planted on and heat up nearby plants. Plants that are heated up too much will be burned out of existence, so ice plants are recommended to keep that from happening. It is also dark in this world, meaning sun doesn't fall from the sky, and mushrooms can be used without the Coffee Bean. The lawnmowers in this world are skeleton hands. The boss of this world is Zombot Demonic Devil.

## In-game Description

*Delve into the depths of hell in the year 666! It's hot down there, so keep your plants cool to beat the heat!*

## Gimmicks

* Fire Plumes

Fire plumes can't be planted on, but if they erupt they will severely heat up all plants in a 3x3 area around them.

* Falling Rocks

Sometimes rocks will fall from the sky and damage plants they land on.

* Lava Pools

These both heat up nearby plants, and spawn zombies. They can be weakened and eventually destroyed by ice attacks.

## Surprise Attack

The surprise attack of this world is called "Hellfire!". When it happens, all Fire Plumes erupt and 5 Literal Imps are blasted to the 4th column.
