Halloween energy has hit Steal a Brainrot, and the Haunted Fuse is the machine everyone is talking about. It turns four ordinary units into a shot at something rare, including the new mutated characters from Update 69. Here’s how it works.

What Is the Haunted Fuse?

The Haunted Fuse is a personal structure for every player. No one else can steal a unit from your machine while your fusion is active, which makes it safer than leaving valuable Brainrots on your base. You can receive both old and new Brainrots from it, including the mutated characters introduced in Update 69. Since it’s open to servers with beginners as well as experienced players, you don’t need a stacked base to try it.

How to Use It, Step by Step

  1. Pick up a Brainrot from your base by holding the E key (on mobile, tap the on-screen button).
  2. Walk to the Haunted Fuse in the middle of the map.
  3. Stand in the Collect Zone to submit the unit.
  4. Repeat until four Brainrots are in.
  5. Start the fusion, then wait for the timer to finish.
  6. Collect your new Brainrot and place it on your base.

Earlier fuse machines in the game charged cash and made players wait longer for higher-rarity inputs. The Haunted Fuse is likely similar, but check the in-game screen for exact costs and odds, since they can change between updates.

What Can You Win?

The headline reward is Phoenix, with a huge base earnings rate of $425 million per second. Don’t expect it every time. The rarest outcomes have the lowest odds, so treat every fusion as a gamble.

Is the Fuse Luck Pass Worth It?

Fuse Luck costs 499 Robux and improves your odds of getting the rarest Haunted Fuse units for 15 minutes. A few ground rules:

QuestionOur take
Should beginners buy it?Probably not. Learn the machine with free runs first.
When does it make sense?If you’re fusing several sets of valuable Brainrots in one window
Biggest riskSpending Robux on a gamble that still isn’t guaranteed

One community guide to an earlier machine suggests keeping your top rare units and fusing only replaceable ones. That’s a sensible rule here too.

Smart Tips Before You Fuse

  • Don’t fuse your best earners. Use duplicates or units you can easily replace.
  • Prepare all four units first so you aren’t wandering the map with valuable Brainrots.
  • Check the odds screen before confirming anything.
  • Skip impulse Robux purchases. Decide your budget before you start.
