To unlock the safe in the “High Rollers” mission, follow these detailed steps:

1. Gain Control of Sevati “Sev” Dumas:
– After Felix gives Sev a copy of the keycard, you will take over as Sev to head downstairs. This is a high-security area where no one else is allowed, so it’s time for stealth.

2. Navigate to the Golden Elevator:
– From the bottom of the stairs, head left toward the gold elevator. The safe will be tucked around the screen to the right of the elevator.

3. Tune the Radio to Get the Code:
– Approach the radio on the left side of the elevator to interact with it.
– Tune the frequency to receive your code. A voice will begin to recite four numbers, which is your safe code.

4. Enter the Safe Code:
– Once you have your code, round around the left of the gold elevator to open the safe.
– Enter the code you heard from the radio to unlock the safe and collect $1,000.

### Additional Tips:
– Stealth is Key: When navigating through the high-security area, use stealth to avoid detection by the guards. You can sneak up behind them and take them down silently or grab a suppressed GS45 on the left desk to make things easier.
– Radio Tuning: The safe code is unique to your playthrough, so make sure to tune the radio correctly to get the correct code. The code is random and different each time you play.

By following these steps, you will be able to unlock the safe and collect the $1,000 reward in the “High Rollers” mission.
