ROB RUN decoder: how to get one and how base raids work
Decoders are the raid key to other players’ bases. Where they come from, what each tier breaches, and how to make your own base expensive to hack.
A Decoder is a disposable raid item applied to a rival’s Security System. Each one lowers the structure’s defence by its breach value, and every Fuse the owner installs raises the number needed. Green breaches 1, purple breaches 3. They cannot be bought — the reliable route is Lenny’s Motel barter: 3 green + $10,000 for 1 purple.
Base raiding in ROB RUN is not a shooting problem, it is a shopping problem. The attacker buys time with decoders; the defender buys time with fuses. Whoever runs out first loses the building.
How to use a decoder
- Find the Security System Every fortified base has one. It is the panel that controls the hack, not the door.
- Apply decoders Each decoder removes its breach value from the panel’s defence. The decoder is consumed.
- Finish the hack When defence reaches zero you get temporary access to the whole building. You do not take ownership of anything.
- Take small valuables first The owner can repair the panel and lock you out again. Assume the window is short.
- Leave if defenders arrive Walking away with an empty bag beats dying with a full one — and your decoders are already spent either way.

Where decoders actually come from
The dependable route is the barter trader behind the Suspicious Door at Lenny’s Motel:
| You give | You get |
|---|---|
| 3 green decoders + $10,000 | 1 purple decoder |
| 1 full purple Action Camera | 1 purple decoder |
| 50 purple decoders | 1 Eviction Right |
Community-documented barters. The Eviction Right is used on a Plot Plan after every Security System in the base is fully hacked.
Green decoders also appear as loot, though nobody has published a reliable drop location. Kefir only says breach tools are rare. The practical rule: keep every decoder you find, and never sell a green one for $1,000 when three of them plus $10,000 make a purple.
Defending against decoders
| Defence | Cost | Effect |
|---|---|---|
| Tier I Fuse | $10,000 research + $20,000 purchase | Raises defence and the number of decoders needed |
| Epic Fuse | $150,000 research + $100,000 purchase | 3 defence points |
| Defence module | Varies | Alerts allies during a raid |
| Repair | Materials | Locks raiders out again; fuses survive a hack |
Community-reported costs from the 6 November client. Fuses are permanent through a hack, which is why they are the correct first purchase.
The economics are simple: a Tier I fuse costs $30,000 and forces the attacker to bring more decoders than the loot is worth. A base with no fuse is a base that costs one purple decoder to enter.
The Eviction Right
Fifty purple decoders — the equivalent of 150 green ones plus $500,000 in barter fees — buy an Eviction Right. Used on a Plot Plan after fully hacking every Security System, it removes a rival owner’s plot and property, though you keep a portion of the assets. This is the endgame siege tool, and it is why large clans stockpile decoders.
