To raid in ROB RUN, use decoders on a rival building's Security System until its defence reaches zero. This grants temporary access to that structure. The owner can repair the system and lock you out, so plan the entry, the loot you want and the way back out before beginning the hack.
Choose the structure you need to enter
Security belongs to individual structures. A fence breach does not automatically open the house, garage or production building behind it. Decide which structure actually contains your target before spending your tools on an outer layer.
Look for its security panel and assess the defence shown there. Installed fuses increase the work required. A large-looking property is not an invitation to assume every building has the same protection or that a single breach will open everything.

Breach the structure at its Security System panel.
Complete the breach and move quickly
- Approach the Security System for the selected structure.
- Use your decoders to reduce its defence.
- Continue until the system is fully hacked and access opens.
- Enter, take the valuables you came for and watch your exit.
- Leave before access closes or the owner repairs the system.
The opening is limited. Do not use it as time to browse every room without a plan. The defender can restore the panel, and a raid can attract the owner or their allies while you are still working.
Know what the hack does not unlock
A decoder breach opens the structure's access points; it does not open the safes and security cabinets inside. Those need a Master Key. Reaching a safe without the right container access is therefore a different outcome from obtaining its contents.
Fuses also survive a normal hack. Repair restores the system's protection, so returning later does not mean the previous breach left a permanent opening. An ordinary raid is not the same as removing the owner's entire property.
Prepare for the defender's response
Fuses make attackers commit more resources, while alarm modules can alert defenders or allies. Assume that a successful entry can be contested rather than treating an apparently quiet base as guaranteed loot.
Carry only what the attempt requires and decide in advance when to leave. Security changes and the owner's response can make the raid less attractive after it starts. If you cannot complete the intended access chain, leaving is more useful than spending tools on another structure that does not lead to the valuables you wanted.
