What is Brainrot Invasion in Plants vs Brainrots?

Brainrot Invasion is a challenging mode, where players have to face 25 enemy waves commanded by five brainrot bosses. The brainrots spawning during this event can damage and temporarily destroy your plants. Clearing each wave will give you several rewards, and after the last wave, the Desert Biome will be unlocked.

Here's everything you must know before facing the invasions:

• Brainrot waves: With an interval of 20 or 30 minutes, you can face a new Brainrot Invasion wave. Each brainrot boss spawns its army in five separate waves. With each successive one, you'll face stronger brainrots and receive better rewards.
• Plant levels: Your plants can now gain up to five levels by defeating brainrots and gaining experience points. With each successive level, the plant's damage and health receive an increase. A way to fast-track this process is by using EXP potions, which can be obtained by clearing waves or using the Plant Extractor machine on the Central Island.
• 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.
