The hacking puzzle is similar to the ones seen in the previous GTA Online updates. You need to find the sequence that matches the sequence shown at the top.
When inside, take out the four security guards inside the room. Be careful of the guard to your left, as he has a shotgun and can instakill you at such close range if you do not have armor.
Then interact with the computer to access the security terminal. Click on 'My Computer' and then click on 'External Device (J:)' followed by 'BruteForce.exe,' which will initiate the second puzzle.
This puzzle is also simple. You need to interact with the scrolling letters when the red-highlighted letters are in the center. This is also seen in many previous DLCs.
After hacking the security terminal. Exit the surveillance room and make your way to the marked area where the limo is parked.
The limo is always in a parking lot within the marked area. So instead of looking everywhere, limit your search to the parking lots.
The limo can have a different color. During our two runs, we got both black and white limos. Once you've identified the limo, you will be asked to follow that limo. However, you do not have to follow the limo and can save a lot of time by simply killing the driver. It will not fail the mission.
After killing the driver, approach the body and recover the driver's wallet.
Deliver the wallet to the agency to complete the mission.
Investigation 2 — Guest List
In this mission, you need to find a way to infiltrate a gathering at the mansion and kidnap the lawyer. Make sure to stock up on armor and snacks.
First, make your way to the mansion. Go through the main entrance and take a right. It is easier to kill the guards when going through the right side of the mansion.
Keep going through the right side until you reach the backyard of the mansion. A lot of guards are going to be at the mansion. Pre-aim while moving so you can easily take them out.
Keep eliminating and moving forward until you reach near the pool area. This is where you will find the lawyer. The lawyer will also have a guard by his side equipped with a shotgun. Be very careful when approaching the lawyer.
After eliminating all the guards, approach the lawyer and equip your stun gun. Shoot the lawyer with a stun gun to incapacitate him. note that you will automatically get a stun gun at the start of this mission, you don't have to buy it.
Once you incapacitate him, a cutscene will initiate, after which you will need to drive the lawyer to the agency.
Enemies will continue to follow you. It is critical not to get stuck anywhere as the guards following you have aimbot. They do a lot of damage and sometimes instantly kill you with a headshot. You can have your snack and armor menu opened up until you get out of the mansion while driving, as this is the only congested place when you start driving.
Keep driving to avoid a lot of damage and deliver the lawyer to The Agency to complete this mission.
The Final Mission — High Society Leak
In the final mission, you finally get to recover the copy of Dr. Dre's stolen music from the Richman Mansion. This mission definitely requires a full stock of armor and snacks.
First, drive to the Richman Mansion and park the car in front of the main gate. Use the interact button to use the security codes to unlock and open the gate.
Keep driving until you reach the main area with the cars and guests. Leave the vehicle and approach the DJ to initiate the next part of the mission. The next part won't start until you get closer to the DJ.
Once Imani starts looking for the source of the music, make your way to the balcony to the left of the DJ booth (just up the stairs). A gunfight is going to erupt and staying up here will keep you a lot safer than down there. Always stay in cover. Use the balcony wall to cover yourself.
You need to destroy the vehicles and kill guards to fill the intimidation bar at the bottom right corner of your screen.
You can also call the 'Detonate Bomb' contract to detonate the DJ's equipment for some more intimidation. This can only be done once.
An attack helicopter also comes, destroy it first and then get back in cover to eliminate the guards.
Once the intimidation bar is full, the billionaire will try to escape using a helicopter.
If you do not have a powerful enough weapon, shooting the helicopter from the balcony won't work. The helicopter also flies away quite fast.
The best thing to do here is to follow it and shoot it while driving. Get off the balcony and go to the left side.
There will be a locked door at the far left side of the yard. Destroy the electric panel to unlock the gate.
We go through this gate because there is a parking lot just across the street. You can quickly get a vehicle and start chasing down the billionaire's helicopter.
Get into one of the vehicles, chase the helicopter and shoot it to destroy it. Enemies will continue to chase you down as well, but ignore them. They will go away once the health of the helicopter is depleted. Using the Micro SMG does an excellent job of damaging the helicopter.
Once you've depleted the health of the helicopter, keep following it until it crashes.
You will get a cutscene of the helicopter crash.
Once it crashes, go to the crash site.
Execute the billionaire and collect his phone.
Deliver the phone to The Agency to complete this mission. If you do not have a vehicle at this point, steal one of the enemy vehicles and drive back to The Agency.
Another piece of Dre's music is recovered. The final leak to tackle is The South Central Leak.
