Access the High Roller Lounge

After starting High Rollers following The Rook: Recovery intermission, walk further into the casino. Meet up with Sev, who’s waiting on the right side, next to a car stand. Pretend to read the info board to Sev’s left, and she’ll give you a cheat card.

As you walk away from the green car, turn right and walk towards the piano. Turn right again to find your poker table:

Access the Casino’s Security Camera System

Once Marshall starts his poker game, you will play as Case again. You’re in the sewers, where you must find three Security Camera Systems. There are guards down here, so try not to let them see you (going in guns-blazing is an option, but it’ll be much harder). You can submerge and swim to safe spots to avoid detection and use the camera to take pictures of guards and track their movements.

Security Camera System 1

As soon as you see the large space with the guards, dive under and swim to the right. There’s a small boat you can hide behind:

Climb onto the ledge behind this boat. There’s a guard on your left, but he won’t see you if you stick to the shadows. Crawl towards the two green barrels and carefully peek around the corner; there’s another guard patrolling this area.

When he turns his back, crawl after him and stick to the right. This will lead you directly to the first Security Camera System:

Security Camera System 2

Sneak onwards. You can stick to the wall on the right to get to the next camera, but as there are many guards in the way, it’s easier to drop down into the water again. Dive under and swim to the other end of the room (opposite of where you came in), then turn right. Roughly follow this route:

Climb up the ledge whenever the guards aren’t looking, and sneak towards the red light, where you’ll find the second Security Camera System.

Security Camera System 3

Turn your back to the previous Camera System, drop back into the water, and swim to the opposite side of the room, until you can go no further. You can see a faint red light from here:

This is where you’ll find the third Security Camera System.

All you need to do now is escape; drop back into the water and go back to the location from where we pictured Security Camera System 3. There’s an exit behind you, up the stairs:

Seen from the entrance of this sewer area, this exit would be in the far left corner.

Acquire a High Roller Bar

The focus will shift back to Marshall playing poker. A prompt will pop up, asking you to pick a cheat card. Make sure you pick ‘full house’ to win the game.

Walk back towards the casino’s entrance. The entrance to the High Roller Lounge is on the left, guarded by the man in the red suit.

Walk to the slot machines on the right and plant a device, then use the execution button as prompted on the screen to create a distraction.

Felix will come in and speak with the casino worker. You must steal his keycard - stay behind him and he won't notice a thing.

Reprogram the Casino Keycard

Shifting the focus to Felix, you must use the keycard to leave this room. Continue using the keycard until you hit a keypad puzzle on a locked door. It’s the same drill as previous keypad puzzles: shine a blacklight to see which buttons have been used before, then adjust the order of the numbers.

Beware: you’ll need the same keypad code to unlock other doors in this area - be sure to memorize it!

Beware that the next area is restricted, so you mustn’t be spotted! You can use the Spy Camera to track the three guards before you head inside (aim the camera at them through the window).

After entering the prohibited section, get down and slowly move left. Only proceed when the nearby guards turn their back. At the end of the hallway, use the same keypad code to enter the office.

Sneak behind the guard and take him out (this will make the rest of this mission much easier), then enter the nearby vent.

Remove the last vent and wait for the patrolling guard to turn his back to you, then take him out. Move onward and wait for the third and final guard to turn his back, then take him out as well.

You’ll find the computer in the corner on your right.

To solve the hacking puzzle, look at the numeral code and enter the corresponding letters. The solutions are ‘copy’ and ‘card’.

Leave the High Roller Lounge and sit down at the bar to your right.

Access the Vault Security Panel

Continuing as Sev, take the door to the high-security area:

The rooms below are guarded, so try to stay out of sight. If you turn left directly after descending the staircase, you’ll find plenty of cover as well as a pistol with a silencer (see picture below). Use it to take down the guards.

In the corner of the room, swipe the security card on the golden elevator.

Optional: Unlock the High Rollers Hidden Safe

Before you leave the golden elevator, be sure to tune the radio on the left side and use the code to unlock the safe on the right side:

Approach the radio to interact, and then tune the frequency to receive your code. If you need more help with that, we've got a guide on how to tune the radio too. Once you have your code, use it to open the safe and collect $1,000.

Blow the Vault

When that’s done, enter the armory on the opposite side of the room. You can grab any six weapons you like to use in combat later - but no more than six!

Note: if you want to complete the Double Down challenge, only grab pistols!

With the weapons loaded, push the cart to Marshall and Felix and place the C4 as instructed. Blow up the vault door, then head inside and collect the loot on your left.

Move the wheel to open the safe, then head back and grab some weapons from the cart. Defend the vault until Marshall yells “to me Sev!”, after which you should push the cart to cause an explosion.

The focus will shift to Case.

Locate Pantheon Evidence

To free yourself from the chair, lockpick your handcuffs and be ready to meet a quick time prompt directly after.

Grab some weapons from this room, then head upstairs and defeat enemies as you approach the locker. After regrouping with the team, you must fight your way out of the casino. Beware of the heavily-armored elite enemies; try to use explosives or move behind them to bypass their shields.

After a final showdown in the canals below the casino, the High Rollers mission will be complete.

Mission rewards

As a reward for completing High Rollers, you’ll obtain a Heist skin for Marshall. You can also collect the following achievements and challenges:

• Jackpot: complete the High Rollers mission.
• Double Down: defend the vault with pistols only.
