The crown jewel of this update is undoubtedly the Radioactive Mutation System. According to the official Steal a Brainrot Wiki, this mutation brings an incredible 8x multiplier to your brainrots, making it one of the most powerful mutations in the game.
The Radioactive Mutation sits just below the legendary Rainbow mutation (10x multiplier) but above the Galaxy mutation (7x multiplier) in terms of power. This makes it an incredibly valuable addition to any player’s collection.
Based on my research of previous mutation events and the official announcements, here are the most likely methods to obtain Radioactive Mutations:
The Radioactive Mutation Update introduces several exciting new brainrots to hunt for. As someone who’s collected every brainrot since the game’s launch, I’m particularly excited about these additions:
| Brainrot Name | Rarity | Special Notes |
|---|---|---|
| Centrucci Nuclucci | Mythic | Radioactive-themed mythic brainrot |
| Swag Soda | Secret | Limited-time secret brainrot |
| [Hidden Secret] | Secret | Yet to be revealed by developers |
Perhaps the most innovative feature of this update is the Brainrot Trader. This revolutionary system allows you to trade your existing brainrots for completely new ones, solving the age-old problem of duplicate brainrots and unwanted collection pieces.
The update introduces an entirely new way to obtain brainrots: Fishing Events. That’s right – you can now literally fish for brainrots! This adds a whole new dimension to the game and provides more opportunities for collectors.
