Plants vs Brainrots Story Mode Guide (All Bosses, Missions & Rewards)

The new Story Mode in Plants vs Brainrots has completely changed how players experience battles.

nspired by the original Plants vs Zombies series, it adds a structured mission system, unique biomes, and tons of rewards, from EXP Bottles to new Brainrots and weapons.

If you’re ready to fight off waves of Brainrots and unlock exclusive areas like the Desert and Jungle biomes, this guide covers everything you need to know about the Story Mode in Plants vs Brainrots.


What Is Story Mode in Plants vs Brainrots?

Story Mode is a series of themed battles where you face off against special Brainrots in increasing difficulty. Each “chapter” is tied to a powerful boss and comes with unique rewards.

Your goal is to defend the garden and prevent Brainrots from destroying your wheelbarrows, if even one breaks, the mission fails instantly.

Each battle introduces new enemy mechanics, damage types, and environmental challenges. It’s also the only mode where you can earn exclusive gear, biomes, and Brainrot variants that don’t appear in the normal game.


How To Start Story Mode

Story Mode unlocks automatically after you’ve completed your initial garden upgrades.

Once unlocked, look for the “Incoming” timer on the right side of your screen. A Brainrot Invasion appears every 30 minutes.

When the timer hits zero:

  • Click Battle to start the mission.
  • If you’re not ready, wait for the next timer and adjust your plants or loadout.

Pro tip: Always place your strongest defensive plants at the end of the garden, the Brainrots deal melee damage, so keeping distance helps you survive longer.
