Welcome to your full walkthrough of the Thrill Seeker mission in Five Nights at Freddy’s: Security Breach, one of the most ambitious and content-packed sequences in the game. This mission weaves together multiple objectives—including Monty Golf, Monty’s decommissioning, and the Monty Claws upgrade—and features stealth, puzzle-solving, boss fights, and more. Buckle in, because this is a long one.

Entering Monty Golf – Party Pass Access

From the main stage area, head to the right to find Monty Golf. You’ll need a Party Pass to enter—give it to the bot guarding the entrance. This pass is consumed upon use, so make sure you’re committed. Take the elevator up, and once inside, proceed cautiously. Security bots patrol the area, and if they spot you, Monty will be alerted. He is fast, aggressive, and easily one of the most dangerous animatronics.

Follow the golf course path until you reach Monty’s Gator Grub. This kitchen area connects to the Security Office. Head left inside, noting the large arrow on the wall—it points directly toward the office. Be wary of a patrolling bot in the room. If you sneak past, you’ll find a present on the control desk containing a flashlight upgrade. Grab it, save your game, and then enter the security office.

Security Room Sweep & Mazer Size Ticket

Collect all the bags and presents in the office, especially the Mazer Size ticket. This item is crucial for progressing the mission. With the ticket in hand, it’s time to exit. Head through the gator-mouth hallway and wait for the patrolling robot to pass. From there, go into the nearby bathroom, which leads to a maintenance area. You can call Freddy for support if needed.

Wait for the patrol bot to move, then dash left and take the escalator. You’ll loop back to the entrance and take the elevator down. While it may seem like the next step is Mazer Size, we first have to make a detour to the Daycare Theater.

Daycare Theater & Mazer Size Control Key

Before heading into the daycare, fully charge Freddy—you’ll need him. The theater is at the back of the daycare. Use the camera to stun patrolling bots and run past them. Once inside, locate the present containing the Mazer Size Control Key. Picking it up triggers all nearby animatronics, but if you’re safely inside Freddy, they can’t touch you. Take this advantage and exit the area carefully.

Head to Mazer Size – Maze Puzzle Solution

Return to the Atrium, go up the right escalator, then left at the top. Mazer Size is beside El Chips. Watch for patrolling bots. Enter the maze and move to the far-left door, where you’ll find a save station and the maze control panel.

The puzzle involves shifting maze rows in four directions. Use the up/down or left/right toggle with row buttons labeled 1–5. Here’s the precise solution:

1. Press “3 Up” three times.
2. Switch to left/right mode.
3. Press “1 Left” once.
4. Switch back to up/down.
5. Press “3 Up” three times again.
6. Switch to left/right.
7. Press “1 Left” twice.
8. Press “2 Right” three times.

This configures the maze to reveal a vent. Hug the left wall and turn right to find it. The hitbox is tricky—edge along the sides until you slide in. No Music Man chase here, so sprint freely.

Monty Boss Fight – Phase Breakdown

At the end of the vent is the Monty boss arena. Save your game before using the large gun to shoot two decorative alligators. Once hit, the boss battle begins.

This fight is all about speed and mobility. You’ll find scattered blaster stations around the area. Your goal is to shoot balls into a goal target until the meter fills. Keep distance from Monty—he can leap between platforms and destroy blasters. Listen for the confirmation tune, which signals the goal is charged. Press the final button, and Monty is finished.

Collect Monty’s Claws and escape via the vent. Again, Music Man won’t chase you, so you can run freely. The vent will take you back through the kitchen and toward the Security Office. Use this moment to save your progress.

Exit Route & Freddy Upgrade

Exit via the bathrooms hallway, avoiding patrols. Go left, take the escalator, and return to the elevator. From here, head to the stage and back into Parts and Services.

Save before upgrading Freddy with Monty’s Claws. Begin the upgrade by disconnecting colored wires in the correct order and inserting the new arm. Follow the memory pattern precisely to avoid a failure.

Once complete, Moondrop will return. Immediately enter Freddy and race to a nearby charge station. With Monty decommissioned, your next mission will target Roxy.

Conclusion

The Thrill Seeker mission is an intricate and satisfying chapter of Security Breach, combining puzzle logic, stealth tension, and a full-on boss battle. With Monty’s Claws in hand and Freddy upgraded, you’ve cleared one of the game’s biggest hurdles. Good luck on your next hunt—and remember, saving often is the best strategy of all.

Thanks for watching, and see you next time!
