Countdown to Steal a Brainrot Cursed Mutation Update
You’re just hours away from the update launch. You’ll soon be able to dive into all the cursed content that’s coming your way. Here is the countdown until the update is live:
What to Expect
This update brings a darker, more evil twist to your brainrots. Developer Sammy kept things light on the new brainrot releases this time because the team is putting all their energy into making the Duels update absolutely perfect for next week. Here’s what to expect:
- Cursed Mutation for Brainrots – Brainrots walking on the belt can now get a cursed mutation that gives them an evil appearance, plus an income booster.
- Cursed Spin Wheel – Try your luck with the new cursed spin wheel that includes a Cursed Secret Block.
- New Gears – Fresh gear items are joining the game through the cursed spin wheel.
- Cursed Index – Keep track of all your cursed mutations and items with the new Cursed Index.
- Cursed Base Skin – Unlock the cursed base skin to give your base an even cooler look.
The update is intentionally smaller than usual, but that’s actually good news. That means you can focus on collecting all the cursed items without getting overwhelmed, and then you’ll be ready to show off your cursed Brainrots in duels when that feature launches.
