Brain Busters are levels in Plants vs. Zombies 2 which are more challenging than usual levels and also add different mechanics, conditions, or objectives to gameplay. They are marked on the map as semi-spheres with striped icons, instead of solid colored semi-spheres like regular levels. In the Chinese version and before the 1.7 update, these were unlocked using world-specific keys. Some Brain Busters are remakes of Plants vs. Zombies mini-games, but most of them are new. Gameplay wise, they play out similarly to the mini-games and puzzles of the first game. Some Brain Busters are exclusive to one world.

The player has to put the plants in the minecarts strategically to destroy the zombies coming out from the corrals. Corrals with electricity indicate that no zombies are to come from that corral for the wave.
The player must match orbs to attack zombies, but if you stall too long, the zombies will eat the endangered plant. There are various types of orbs, each powering a specific plant.
The player controls a Dodo Rider Zombie past danger to get to the end. This is the 2nd brain buster in which the player controls the zombie(s) instead of the plant(s). The dodo has 3 lives. If the dodo touches the Chomper, gets bit by the Guacodile or falls in the water, the dodo will lose a life. If all 3 lives are lost, the game is over.
Plant packets and hypnotized zombie packets fall from the sky, the player has to plant these in the right place in order to defeat the zombies. This Brain Buster is very similar to the mini-game It's Raining Seeds from the first game.
In Part 2, there is a Brain Buster that includes the use of two types of Trap Tiles, a fire tile and a boulder tile which will activate their respective elements, damaging plants and zombies. The player has to use these tiles to their advantage to defeat the zombies. The fire tile spreads flames on one lane, which incinerates plants and zombies, while a boulder tile sends a boulder down two columns, wiping out anything in its way.
In this Brain Buster, a storm is taking place in the lawn, and the screen will remain dark until lightning flashes, giving the player a brief moment to see what's happening. It is similar to Level 4-10 of Plants vs. Zombies.
The player must break vases to reveal plants seed packets, sun, zombies, or Plant Food. The player has to use the plants he/she gets from the vases to kill the zombies broken from vases.
Played on Lost City - Day 16.
In this Brain Buster, there are only three lanes that can be planted on.
Played on Lost City - Day 21.
All sun-producing plants except for Gold Bloom, Sun Bean and Toadstool cannot be used. Sun falling from the sky is purple before reaching the ground, turning into their regular yellow shade. Purple sun will explode, taking out plants and zombies only if the player touches them before they reach the ground. However, sun falls from the sky twice as often compared to a normal level.I, Zombie from Plants vs. Zombies, there are plants on the lawn which need to be destroyed in order to beat the level. The player must spawn zombies to eat the plants. Every eaten plant is worth 150 sun.
The plants do ten times their normal damage, and have a faster shooting rate in this Brain Buster. However, there is only one plant available for use. The plant gets XP when killing zombies, and if the plant has enough XP, it will upgrade into a stronger plant. Players need to move the plant on a cart and dodge bombs.
In this Brain Buster, hands which come from the ground leave "evil" potions on the lawn that can give zombies helpful effects. Visually, the zombies will look bigger when they touch certain potions.
The orange potions make zombies walk faster while the pink potions give them a 25% health increase, according to their maximum health.
In this Brain Buster, the player must defend The Little Pigs from zombies in wolf costumes. All zombies move along a predetermined path. Any plants planted at the left side of the path will be eaten. The zombies have much higher health in this Brain Buster. This is the only Brain Buster to have a completely unique lawn design.
In this Brain Buster, the player must fight zombies only with Hypno-shrooms while "evil" potions appear.
In this Brain Buster, the player must operate Oak Archer to shoot incoming zombies.
In this Brain Buster, the player must use the four types of bulbs from the Bowling Bulb given from a conveyor belt to kill the zombies. Different types of bulbs deal different amounts of damage. The bulbs given are the basic trio of bulbs, along with a Plant Food-powered one. This is similar to Wall-nut Bowling from the first game.
The player controls a Guacodile line which slowly gets longer and longer. The player must try to defeat all the zombies without touching any of their other Guacodiles. The lawn is much larger, and the zombies are smaller. This is the only Brain Buster to have small zombies. This resembles the classic video game Snake.
In this Brain Buster, the player must break vases to reveal plant seed packets, zombies, or Plant Food. The player has to use the plants he/she gets from the vases to kill the zombies from the vases.
In this Brain Buster, the lawn is filled with plants and the player must swap them either horizontally or vertically to make a match of 3 or more plants which will make them disappear and give sun. Make a match of 4 or more plants will activate their Plant Food effect. Matching three armored defensive plants gives the player significantly more sun than usual. The player can use the sun to upgrade the plants into different plants. The player must make a certain amount of matches to defeat the level.
The player must use the plants given to them via conveyor-belt. There are a certain number of petrified Gargantuar Bronzes that will attempt to free themselves from petrification given by the timer. These petrified warriors can be destroyed by plants. If the player fails, the Gargantuar Bronze is free from petrification and is ready to smash the Player's line of defenses. The more petrified Gargantuar Bronzes are there, the harder the battle becomes. The player wins when all zombies are killed.
The player must use a turret to destroy waves of zombies.
The player chooses one from three plant teams and controls a flying plant to defeat incoming zombies.
Similar to the Fright Theatre, the player must defend the house from the zombies before destroying it.
