To raid other players in Rob Run, use Breach Decoders on each building’s Security System until its Defense reaches zero.
Your main decision is how many decoders to commit, and whether a target justifies that cost. A lightly protected Trailer and a fully upgraded Mansion need very different supplies, even though you breach them through the same mechanic. Plan around the specific structures you want to enter, not the size of the property alone.
Where to get Breach Decoders
Find Uncommon Decoders through looting
Uncommon Decoders turn up in safes, cabinets, containers, and robbery loot. Decoders are consumables, so collect a stock before starting a player raid. Finding one is a start, but most secured structures require several installations.
The Season 1: Pure Chemistry battle pass also offers an Uncommon Decoder on page three for 3,000 season currency. Treat that as a specific pass reward, not a repeatable replacement for looting.
Uncommon Decoder inventory
Trade for Epic Decoders at Lenny’s Motel
The barter trader behind the Suspicious Door at Lenny’s Motel offers an Epic Decoder through either of these exchanges:
- Three Uncommon Decoders plus $10,000 in in-game cash.
- A filled Action Camera.
If you choose the cash exchange, include its $10,000 fee in your Rob Run money-making plan before setting a raid budget. The filled Action Camera exchange lets you keep your Uncommon Decoders, provided you have the required camera ready.
Which decoder should you use?
Decoder rarity determines how much Defense each installation removes. Each installation takes around 12 seconds, so stronger decoders reduce the time spent working on a terminal.
| Decoder | Defense removed per installation | Installations for 15 Defense | Approximate installation time |
|---|---|---|---|
| Uncommon | 1 | 15 | 3 minutes |
| Epic | 3 | 5 | 1 minute |
| Legendary | 5 | 3 | 36 seconds |
These estimates cover installations only. Travel, moving between structures, and collecting loot take additional time.
Trading three Uncommon Decoders for one Epic Decoder does not increase their combined breaching power. Both options remove 3 Defense, but the Epic version needs one installation instead of three. At roughly 12 seconds per installation, that exchange saves about 24 seconds of terminal work.
Use Uncommon Decoders when you want to spend your existing stock without paying for the cash barter. Epic Decoders compress that work into fewer installations. Legendary Decoders remove the most Defense per use, but you still need to budget separately for every secured structure on your route.
How many decoders does a player base need?
For a single decoder rarity, divide the structure’s current Defense by the Defense removed per installation, then round up.
Check the structure and its fuse upgrades
Each structure has its own Security System. Opening a house does not also unlock its garage, warehouse, workshop, grow room, or secured fence. A property with several buildings can therefore require several separate breaches.
Fuses increase Defense above a structure’s starting value, while the number of fuse slots stays fixed for that structure type. Mansions have the highest maximum Defense among the structures below, but a building’s type alone does not tell you how heavily its owner has upgraded it.
The final column shows the decoder cost when every fuse slot contains a Legendary fuse. Each set of three numbers assumes you use only one decoder rarity throughout that breach.
| Structure | Base Defense | Fuse slots | Maximum Defense | Decoders at maximum: Uncommon / Epic / Legendary |
|---|---|---|---|---|
| Trailer | 5 | 9 | 50 | 50 / 17 / 10 |
| Small House | 15 | 27 | 150 | 150 / 50 / 30 |
| Mansion | 30 | 42 | 240 | 240 / 80 / 48 |
| Car Garage | 4 | 6 | 34 | 34 / 12 / 7 |
| Large Car Garage | 6 | 12 | 66 | 66 / 22 / 14 |
| Warehouse | 10 | 15 | 85 | 85 / 29 / 17 |
| Workshop | 5 | 9 | 50 | 50 / 17 / 10 |
| Grow Room | 5 | 9 | 50 | 50 / 17 / 10 |
| Chemical Laboratory | 3 | 6 | 33 | 33 / 11 / 7 |
| Mesh Fence | 2 | 3 | 17 | 17 / 6 / 4 |
| Metal Fence | 5 | 6 | 35 | 35 / 12 / 7 |
| Concrete Fence | 10 | 9 | 55 | 55 / 19 / 11 |
Use the terminal’s current Defense when planning an actual breach. The maximum column is a fully upgraded limit, not the cost of every building of that type.
Mansion player-base building
Calculate each breach separately
A no-fuse Trailer has 5 Defense, so it needs five Uncommon, two Epic, or one Legendary Decoder.
Budget one structure at a time. If your route crosses a no-fuse Mesh Fence and then enters a no-fuse Car Garage, the fence needs one Epic Decoder, and the garage needs two. Bring three Epic Decoders for that route, even though their combined Defense is only 6.
Fences on farms are an exception: they do not have a Security System and cannot be hacked. Do not include them as decoder targets.
Compare the full route cost with your Rob Run progression budget before spending a decoder at the first terminal. If you can afford the outer breach but not the building behind it, save your supplies or choose a cheaper target.
How to breach the base and finish the raid
Work through your planned structures
At the target, find the structure’s Security System and check its Defense. Apply the decoders you budgeted for that terminal, watching the remaining number as you work through the breach.
Follow this sequence:
- Confirm the target. Check that you are breaching the structure you actually want to enter.
- Match your stock to its Defense. Recalculate if its protection differs from your estimate.
- Install the required decoders. Continue until that terminal reaches zero.
- Enter through the opened access points. Zero Defense grants temporary access through that structure’s doors, gates, and windows.
- Collect your chosen loot. Treat any additional secured building as a new breach with its own cost.

Account for a response from defenders
Defense modules can alert the owner’s allies to an ongoing attack. A defended base can draw a response while you are still installing decoders, so include installation time in your target choice, not just the number of items you can afford to spend.
Once inside, prioritize the valuables you intend to carry out. The Rob Run loot guide covers choosing a buyer and protecting your cash after the robbery.
Leave when your planned haul is complete. Starting another terminal without enough decoders commits more supplies before you can access its contents.
