Backstory
'''The story takes place after Plants vs. Zombie 2: It's About Time! -- Spoilers may be at risk.'''

After Dr. Zomboss traveled through time, he took a long break but only to come back with a stronger and greater invention. He created the "Dusk-Destroyer 9000", a mechanism that would make all the light in the world and realms disappear.

Shortly after, Dave and Penny find out about this and tell us, the neighbor. As days roll by, it appears to be getting darker; so Dave knows that this is a new beginning. They start by protecting their home, and then fleeing to a new realm. That is where the journey begins, and where we need to save and create light in the world.

Meanwhile...

The zombies are creating a plan to move across different realms and create darkness everywhere they go using the Dusk-Destroyer 9000. Everywhere that was light became dark. The only way to combat the dark was light, but barely any was to be seen.

Areas
Area 1 acts as a tutorial for Plants vs Zombies: A Darkness Rising. This demonstrates the core mechanics of the game-- the first day being a normal day with the rest being dark. It also demonstrates no sun falling from the sky and graves.

Realm 1 is the official starting of the game. This realm has 25 stages and 5 plants. The core mechanic of this realm is nothing, as it is just the first realm. It is inspired by Asian and oriental themes.

Realm 2 has 25 stages and 5 plants. The core mechanic of this realm is the ice, which makes zombies perform an animation where they slip and kick the plant in front of the tile. (Similar to this) If there is no plant in front of the tile, the zombie will move on.
