After the mind-bending events of the Emergence mission, the gang is back in action in search of Fucina, a clue Felix extracted from a video featuring Gusev, the mastermind behind The Cradle bio weapon. It appears an Avalon faction is associated with Pantheon with the latter bankrolling research using funds from the casino. To figure out what’s going on, you’re heading back to Avalon to stage a heist to find out what the Pantheon has under wraps in the B24 safety box in the Casino Luttazzi’s Archive Room.

In this guide, you’ll find a full walkthrough for the Black Ops 6 campaign’s seventh mission, High Rollers. We’ve structured the guide around the mission objectives, which you can go straight to as required by using the list on the right.

Acquire Playing Cards from Sev

As soon as you gain control of Marshall, head towards the objective marker to the right of the reception desk into the room with the playing tables and slot machines, then head to the back and interact with the placard. Sev will hand over the playing cards.

Play High Stakes Poker

Head to the room past the blackjack tables to the right of the piano as indicated by the objective marker. Take a seat and chat with Badeaux. The poker game will start and you’ll switch over to control Case.

Access the Casino’s Security Camera System

Swim forward through the water and deal with the guards ahead. It’s worth swimming underwater to remain concealed, heading right, then emerging and methodically taking out all the enemies quietly with headshots from your silenced pistol to prevent them calling reinforcements. 

Hop out of the water and access the junction box on the right. Climb up the ladder next to the junction box then use the gangway to make your way to the next box. Pick off any remaining guards then jump down and interact with the next junction box. Grab the final junction box on the other side of the area.

Enter the Casino

Head to the objective marker. Climb the stairs and follow the corridor to the top and go through the door. You’ll get captured by a duo of security guards and be taken to an interrogation room.

Access a High Roller bar

Back in control of Marshall, you’ll need to win the poker game to get a High Roller Bar and gain access to the High Roller Lounge. Select either of the dialogue options when prompted. Woods will reveal Badeaux’s cards and Sev will step in to distract everyone and give you time to pull a card from your sleeve. Select either Full House or Four of a Kind when prompted to win the game and get the High Roller Bar. Make your way over to the High Roller area, interact with the clerk, and head inside.

Create a Distraction

Plant the scrambler on the slot machine next to the door on the right of the High Roller room. Trigger a jackpot when prompted to create a distraction. When Felix shows up, steal the keycard from the attendant.

Reprogram the Casino Keycard – Access the Server Room

Go through the door at the back of the High Roller room using the keycard on the reader to the right of the door. Make your way through the backroom to the server room.

Reset the slot machines

Walk over to and interact with the server rack to reset the slot machines.

Reprogram the Casino Keycard

Use the keypad to access the room on the right as indicated by the mission objective marker. The code is 780, which you deduce by using the blacklight to search for fingerprints. Head through the door. It’s a restricted area so stay concealed otherwise you’ll fail the mission. It’s worth performing Silent Takedowns on the patrolling guard to make navigating through easier. 

Head to the locked door to the left of the area and use the keypad to get inside. The code is 780. Silent Takedown the guard inside then remove the vent cover and crawl inside the system. Go forward and take the second right then remove the vent. Exit and stay to the left to avoid the camera. 

Press on down the corridor all the way to the end and use the keypad to unlock the door on the right. The code is, once again, 780. Wait for the guard to move, then immediately go through the door and take a right into the server aisles. Head for the objective marker in the corner of the room and interact with the computer. You’ll need to solve a cypher puzzle to reprogram the keycard. The solution is CARD COPY.

Deliver the Keycard to Sev

This will alert the guard. Make your way back to the room where you reset the slot machines, avoiding the guard or taking him out. Retrace your steps and get back to the casino floor. Exit the High Roller area and then go over to the bar on the right to hand over the Keycard to Sev.

Access the Vault Security Panel – Reach the High Security Area

When you gain control of Sev, make your way over to the door near the caissier desk as indicated by the objective marker. Swipe the keycard and enter. Take a right then into the room on your right.

Unlock the Elevator

Follow the stairs down and take a left. Grab the pistol from the desk and take out the guards. Make your way over to the elevator. To the left of the elevator is a radio. Interact with it and tune both frequencies so they match. Note the message – 2246. Go to the right of the elevator. Behind the separator is the safe. Enter the code 2246 and grab the $1000 inside. Swipe the keycard on the elevator to unlock it.

Acquire Weapons

Turn around and make your way over to the objective marker and into the armory. Grab six weapons and stow them in the cart. There’s also $200 on the table next to the sofa at the back of the room. 

Blow the Vault

Push the cart out of the armory and to the vault entrance to meet up with Marshall and Felix. Grab the C4 from the bag and plant it on the vault door. Move away from the door and then detonate the charges. Enter the vault, grab the armor plates and other gear on the left, then interact with the lever straight ahead to reveal the panel.

Defend Felix

Grab a weapon then fend off the advancing guards. After the first few waves, crouch down near Marshall and push the cart to clear out the remaining guards.

Locate Pantheon Evidence – Reach the Archive Room

You’ll jump to Case in the basement. Complete the lockpick mini-game to free yourself from the handcuffs and complete the quick time event. Grab some weapons then head up the stairs. Take out the guards then take a left. Press on, clearing out the guards as you go until you reach the Archive Room. Head to the back corner and open the B24 lock box by completing the lockpicking mini-game.

Rendezvous with Team

Retrace your steps out of the Archive Room and head forward. Take out the guards and press on to meet up with the gang.

Escape the Casino

Go up the stairs on your left. Stock up on weapons at the top, then enter the casino floor. Press on to your right, taking out the guards as you go. You’ll reach a large hall and several Pantheon enemies will show up, including two shielded soldiers. Use grenades to stun them then fire into them when they are vulnerable. Clear out the area and go through the door to the left of the stairs.

Go down, stock up on ammo and weapons, then head into the canal area. It’s teeming with Pantheon enemies, including one elite. Pick them off quickly and avoid the traps. Make your way over to the boat and untie it to wrap up the High Rollers quest and unlock the Jackpot trophy. Up next is Ground Control.
