Welcome to the complete Dumpster Diving mission walkthrough in Five Nights at Freddy’s: Security Breach. This mission ties together several major objectives including Phaser Blast, Monty Mystery Mix, and Chica’s Beak, culminating in the dramatic decommissioning of Chica herself. If you’re ready to take on one of the more stealth- and combat-heavy routes in the game, read on.

Step 1: Entering Phaser Blast

Start by heading down from Salads and Sides toward Phaser Blast. Give your Party Pass to the bot at the entrance and head inside. You can bring Freddy if you want, though he isn’t required.

Once inside, go left to the security office. Be sure to grab everything—especially the Bonnie Bowl access pass, which is key to the next phase. Afterward, ignore the patrolling lobby bots and proceed straight through the door.

Pick up the Phaser Blaster from the display and move into the arena.

Step 2: Capturing the Control Points

Your goal here is to defend three capture points while fending off hostile bots:

• Checkpoint 1 – Located near the entrance.
• Checkpoint 2 – In the orange sector. Take the correct hallway or risk a dead end.
• Checkpoint 3 – Upstairs, on the second floor.

Use the Phaser Blaster to defend each flag. If Chica appears, stun her and retreat if necessary—you can always retry the capture. Robots can steal the flag if they spend too long at the point.

Once all points are captured, head to the winner’s elevator (marked by a crazy robot face). Return the blaster and claim your permanent Phaser Blaster in the security office upstairs.

Step 3: Vanny Secret Ending Unlock (Optional)

Before leaving the security office, crawl into the side vent. This reveals Vanny’s secret hideout and unlocks a future ending path when exiting the Pizzaplex.

Step 4: Bonnie Bowl & Monty Mystery Mix

Go to the third floor and head to Bonnie Bowl, located on the same side as Phaser Blast. Present your bowling pass and bring Freddy—his help is critical.

Inside, proceed to the back kitchen area. Grab the Monty Mystery Mix from atop a cabinet. This triggers aggressive animatronic spawns. Quickly hop into Freddy to bypass threats and exit through the elevator.

Step 5: Heading to the Loading Dock

Return to Salads and Sides. Instead of using the vent, go through the door beside the save station—it leads to an elevator that takes you to the Loading Dock.

Step 6: Trash Compactor Setup

In the kitchen area, avoid the right-side blue door—it’s a trap; Chica lurks there. Instead, proceed forward to reach the trash compactor generator room. Stun Chica if she appears, then activate the generator.

Back in the kitchen, place the Monty Mix in the trash compactor and activate it. Enjoy the cutscene as Chica gets absolutely dumpstered.

Step 7: Navigating the Wreckage

Collect Chica’s Beak from her broken body. Now, navigate the trash-filled corridors. Activate the nearby generator to unlock the next door, but be prepared—Chica revives and begins hunting again.

Use the Phaser Blaster to stun her and follow the cord path to escape. Be very cautious of environmental hazards—falling from narrow boards is fatal.

Step 8: Escaping the Garbage Caves

In the next section, Chica emerges from the right. Immediately turn left to avoid her. You’ll hear her footsteps, so use them as cues. Find the next generator and move forward. The cord will lead you to the exit door.

Step 9: Security Bot Gauntlet & Final Generator

In the following area, security bots with eerily familiar painted faces patrol. Sneak past them, or use distractions. On the second floor, stun Chica and activate the final generator.

Move quickly, as Vanny may now appear. Once you pass through the next door, she’ll stop pursuing you.

Step 10: Hidden Lore & Exit Path

Optionally, explore this area to find eerie easter eggs, including robot replicas of the Afton family. Continue up the long staircase, save at the top, and open the next door to return to the Loading Dock.

Take the elevator out and prepare for your next step.

Step 11: Freddy’s Upgrade – Installing Chica’s Voice Box

Return to Parts and Services, save your game, and begin the voice box upgrade:

• Remove the chest plate
• Disconnect and replace the throat wiring
• Reattach the chest plate

Once complete, Freddy will now speak with Chica’s voice—opening paths blocked by her unique security doors.

Mission Complete

With Chica now decommissioned and Freddy upgraded, you’ve wrapped up Dumpster Diving, Phaser Blast, Monty Mix, and Chica’s Beak missions. The next chapter? Head to Roxy’s Raceway and prepare for the next big showdown.

Thanks for following along, and as always—good luck out there in your own games!
