Brainrot Invasion is the new Story Mode added to the game, where players get to face waves of brainrots commanded by the Noobini King. Clearing each wave will grant you several rewards. The brainrots spawned during the Brainrot Invasion can damage your plants by eating them. Here's everything you must know before entering Brainrot Invasion:

• Brainrot waves: With an interval of 15 minutes, you can face a new Brainrot Invasion Imminent wave. The waves are commanded by Noobini King. With each successive wave, you'll face stronger brainrots and get better rewards.
• Plant levels: Your plants can now get leveled up by defeating brainrots. With each successive level, the plant's damage and HP increase.
• Desert biome: By clearing all the Brainrot Invasion waves, you can unlock a Desert biome. On entering this biome, your base will get a desert environment, increasing the odds of spawning new brainrots.
