Your first introduction to Braindance in Cyberpunk 2077 will take place during a mission called The Information. You need to search through a scene captured by Ev to find clues for a job you are planning.
You will need to search through the scene at various times, and because it is your first Braindance, you may find it a little confusing. You will need to find the datapad and the Relic safe but can also scan the security equipment for some extra information when you play through the job.
The Security equipment can mostly be found right at the start when Ev enters the room. Pause the playback and scan the security pad directly beside the door. You should also be able to scan the camera in the bedroom through the wall. Just hover the reticle over each of them, and wait until the scanning bar is full.
The final piece of security equipment is a turret in the ceiling, just above the bedroom that you can scan when Ev is heading there with the target.
The Data Pad
You won’t be able to scan the datapad until near the end. The target will be lying on the bed reading the datapad. This is the only window you will have to scan it, and you will need to be in the yellow, visual layer to do it.
The Relic Safe
For the Relic safe, you will need to be in the thermal layer, and pretty much back at the start of the recording, when Ev is standing at the counter getting a drink. You can find the safe in the floor in the far corner of the room, near the windows.
