ROB RUN Decoder Guide: How to Get One, Raid a Base and Beat Fuses
A ROB RUN decoder can't be bought. Where each tier comes from, how many open a Small House (15 to 150) and how fuses push raiders to the next base.

A decoder strips 1, 3 or 5 defense points off a building's Security System, and at zero the building opens. If you raid solo, know your count before you start, because every decoder takes 12 seconds. These numbers come from the November 6 early access update, and Kefir can change them.

- Uncommon, bare Small House

- Uncommon, Small House, max fuses

What does a decoder do in ROB RUN?
It lowers a building's defense on its Security System and is gone after one use. Defense is the building's base level plus every fuse the owner put in.
Each decoder takes 12 seconds and removes its breaching from that defense. At zero, every door, gate and window of that building opens for a while.
The owner can repair the panel and lock you out again. So grab what you came for and leave.
Words to know (3)
- Security System
- The panel on each building's wall. It holds the fuses and alarms, and it's where you use decoders.
- Breaching
- How many defense points one decoder removes: 1, 3 or 5.
- Fuse
- An Electronic Fuse the owner puts in a panel slot. It adds 1, 3 or 5 defense.
One hack opens one building, not the whole base. The garage, the Grow Room and even the fences have panels of their own.
A decoder also stops at the door of a safe. Safes and security cabinets inside need a Master Key.
How do you get a decoder in ROB RUN?
You can't buy one, not even on the Black Market. Uncommon and Epic each have a route. Legendary has none yet.
Here is what each tier does and where it comes from:
| Tier | Breaching | Where to get it | Sells for |
|---|---|---|---|
| Uncommon (green) | 1 | Battle pass, page 3 (free, until Dec 4) | ~$1,000 |
| Epic (purple) | 3 | Barter at the Suspicious Door | ~$5,000 |
| Legendary (gold) | 5 (game files) | No known source | ~$40,000 |
The game files list the Legendary decoder at 5 breaching, but no seller, barter or reward gives it. Reports of Legendary decoders found in loot are unconfirmed.
Decoders also drop as rare heist loot, and players report finds in store cabinets. Nobody knows the drop rate, so open every cabinet and keep what you find.
How do you trade for an Epic decoder?
Bring 3 Uncommon decoders and $10,000 to the Suspicious Door, the barter trader inside Lenny's Motel. The motel is a safe zone, so nobody can shoot you inside.
Collect 3 Uncommon decoders and $10,000 in cash.
Open the global map, pick Lenny's Motel and press Enter.
Go inside and open the Suspicious Door on the right.
Pick the Decoder to see what it needs.
Make the trade.
The same door also trades one full epic Action Camera for an Epic decoder. The camera fills up as you commit crimes.
Compare what each route costs you, counting the items at their sell price:
| 3 Uncommon + cash | total 13
|
|---|---|
| Action Camera | total 100
|
The Uncommon route is highlighted because it's the cheap one. A full epic camera sells for about $100,000, against about $13,000 for the first route. You keep about $87,000 of value.
Holding a full camera? Sell it. That cash pays for fuses, and the Epic decoder alone sells for about $5,000.
Three Uncommon decoders and one Epic remove the same 3 points. The Epic does it in 12 seconds instead of 36, which matters when the owner gets an alarm.
How many decoders do you need to raid a base?
Add the building's base defense and every fuse's points, divide by your decoder's breaching, and round up. Base defense differs a lot between buildings:
| Mansion | 30 |
|---|---|
| Small House | 15 |
| Warehouse storage | 10 |
| Concrete Fence | 10 |
| Trailer | 5 |
| Grow Room | 5 |
| Chemical Laboratory | 3 |
| Mesh Fence | 2 |
The Grow Room and Chemical Laboratory are highlighted. They make money and have some of the lowest base defense, so they open with the fewest decoders.
A Small House shows how fast fuses add up. It has 27 fuse slots. Here is how many decoders of each tier it takes:
| Small House | Defense | Uncommon | Epic | Legendary |
|---|---|---|---|---|
| No fuses | 15 | 15 | 5 | 3 |
| 5 legendary fuses | 40 | 40 | 14 | 8 |
| 10 legendary fuses | 65 | 65 | 22 | 13 |
| All 27 legendary fuses | 150 | 150 | 50 | 30 |
A fully fused house takes 50 Epic decoders, or 10 minutes at the panel. An alarmed owner has plenty of time to come home.
How do you raid a base with decoders?
Pick the weakest building that holds something worth taking, then hack it fast.
Pick a building with low defense, like a Grow Room or Chemical Laboratory.
Bring decoders for the gate and the building's base defense, plus spares for fuses.
Pack a Master Key if you're after a safe.
Hack the gate first, from outside the fence.
Look at the building's Security System and press E to Breach, until defense hits 0.
Grab the loot and leave before the owner repairs the panel.
Don't jump the fence to save decoders. Players who jumped in report getting stuck: the gate wouldn't hack from inside, and they couldn't use the owner's car.
A full hack also starts a raid block, which locks some of the owner's base actions for a while.
Want the whole plot? The game files list an Eviction Right for 50 Epic decoders, used after every panel on the base is hacked. An earlier official FAQ tied base wipes to a rare loot-only item instead, so treat it as unconfirmed.
How do fuses on the Security System stop decoders?
Every fuse adds its points to the panel, so raiders need more decoders and more time. Fuses come in three tiers:
| Fuse | Adds | Price | Research |
|---|---|---|---|
| Electronic Fuse (uncommon) | +1 | $20,000 | $10,000 |
| Electronic Fuse (epic) | +3 | $100,000 | $150,000 |
| Electronic Fuse (legendary) | +5 | $250,000 | $500,000 |
Research is an extra cost on top of the fuse price.
The +1 fuse is the cheapest per point, $20,000 against $50,000 for +5. But slots run out, and only +5 fuses take a Small House to 150.
Fuses survive a hack. Repair the panel and the full defense comes back.
Each panel also has 3 alarm slots. Alarms add no defense. They only warn that a hack has started, and the tier decides who hears it:
- Playing solo: the epic alarm warns only you. A raider needs 12 seconds per decoder, so you may make it back.
- Clan online: the legendary alarm warns you and the whole clan.
- Busy settlement: the uncommon alarm warns everyone at the location, so neighbors hear it too.
Nothing protects an offline base, so fuses and alarms are your whole defense. Fuse the Grow Room and Chemical Laboratory first, because they make money and open with the fewest decoders.
Spread your cash, loot and unopened cargo over several buildings. Each one needs its own decoders, so a raider may run out halfway.
And close your doors. A door left open lets anyone who jumps the fence walk straight in.
So count the defense before you hack, and fuse your money buildings first.
FAQ
How much is a Legendary decoder worth?
You can't buy one. It sells for about $40,000, and no known source gives it yet.
Does a decoder open safes in ROB RUN?
No, safes and security cabinets need a Master Key. It's free on page 3 of the battle pass. The Black Market sells it after a $50,000 Shipments unlock in a level 2 or higher settlement.
What happens to my fuses after a raid?
They stay in the panel. Repair the Security System and your full defense is back.
