How to Fuse Bunkers in My Bunker

The fuse machine in My Bunker is how a spare model becomes a named upgrade, not how you gamble your only earning pad. Yeet Pizza Productions put the machine on the plot next to the rest of the six-player tycoon. A recorded opening session found it beside Halloween event dressing and treated the window as a Halloween fuse UI around the same machine.

This wiki lists three confirmed recipes and stops there. If a Discord screenshot names a fourth pair, it does not go on this page until gameplay or a devlog shows it.

Confirmed recipes

Space into Black Hole. If you open or otherwise own Space, the fuse machine is the confirmed path to Black Hole. Do not sell or ignore Space because it looks like a mid bunker; it is a part. Black Hole is the output we can name. We do not publish a cash cost, a wait timer, or a failure rate because none of those figures are recorded as official.

Steampunk plus B. Recorded play pointed at the machine and said this is where the B bunker and the Steampunk bunker come together. Bring both. One half sitting in inventory is not a fuse. We do not list a third filler item for this recipe.

Rogue robot into Lockdown Ultimate. A Rogue robot is the confirmed input for Lockdown Ultimate. In the recorded session the player called that path the best current bet at an Ultimate. Lockdown itself is a separate bunker; a recorded run showed regular Lockdown at about $200 per second before anyone fused an Ultimate. Do not confuse the two names.

That is the full recipe list on this wiki. No bank-plus-cop line. No Prison fuse. No Nature fuse. No Electric or Graveyard fuse. No invented Halloween candy recipe even though the UI can wear event art.

What a recorded session guessed and then skipped

During the same opening video the player talked about fusing a regular bank bunker and a cop with a prisoner to make a Prison version, then opened a crate and received Prison anyway. This page does not promote that bank recipe. Prison is a bunker you can roll from a crate, which is covered on How to Get Bunkers. Until a devlog or a clean fuse result shows the bank pair, treat it as chat, not a guide step.

Halloween fuse dressing is the same rule. The machine was visible during an event. The confirmed outputs did not change on camera. If a later patch adds an event-only pair, it belongs on updates first, then here after we can name both inputs.

When to walk to the machine

Fuse after the plot already prints. If Space is your only pad, placing it beats fusing it. If Steampunk is your best earner and you do not own B yet, wait. If you finally have a Rogue robot and your other pads are guarded, that is the Ultimate trip.

Empty pads still want cheap conveyor crates, not a fuse. The loop on How to Play puts fuse last on purpose: cash, crate, bunker, guard, upgrade, then fuse. Getting Started should be finished before you feed the machine anything you cannot replace.

Guards do not fuse. Artifacts do not fuse. Mutations such as Rainy are tags the index shows; they are not fuse inputs on this page. If a Rainy Space is the only Space you own, you are still spending a Space when you make Black Hole. Decide that with the bunker tier list open, not with a guess.

After a successful fuse

Place the output. Hire a guard if the new pad is empty. Check the index so the new name and any mutation icon actually register. Then go back to the conveyor. Fusing is not a replacement for crate spawn upgrades.

Offline cash still depends on placed bunkers. A Black Hole sitting in the machine window helps nobody after logout; offline earnings assume the model is on a pad. If you are planning the next spend, the income planner is for crate-versus-upgrade math, not for inventing a fourth recipe.

There are no confirmed codes that skip the machine. There is no official Trello of recipes. Scripts labeled for “Build a Bunker!” will not fuse My Bunker models; see the scripts hub only with that split in mind. Live shouts stay on official links and the Yeet Pizza Productions group.

If you remember nothing else, remember the three lines: Space becomes Black Hole, Steampunk wants B, a Rogue robot becomes Lockdown Ultimate. Everything else is a crate roll, a mutation icon, or a rumor this page refuses to print. The Guides Hub sends you back to crates and guards when the machine has nothing valid to eat.
