Final Boss Guide - Five Nights at Freddy's: Security Breach Guide - IGN (2024)

If you're attempting to complete Five Nights at Freddy's: Security Breach by achieving its true, canon ending, you'll have to defeat a familiar face. Returning from his fiery fate at the conclusion of Five Nights at Freddy's: Pizzeria Simulator (AKA Five Nights at Freddy's 6), William Afton is back and he's ready to kill you to protect his secret.

To reach this boss, you'll have to complete a few side objectives. You can take a closer look at the lead-up via IGN's Canon Ending Guide. When you do come face to face with Afton though, here are some tips to help finish him off for good.

How to Defeat William Afton

After falling into Afton's chamber, a cutscene will play showing the malevolent, purple-obsessed serial killer emerging from a recharge booth in his Spring Bonnie outfit. Once his entrance is complete, the fight will begin.

Now, the rules to this fight are, on paper, quite simple. Afton won't outright engage Gregory, but will wander between three locked rooms. In these rooms, he'll try to control Freddy by placing his his hand on TV screens, causing the lights to flicker and Freddy to convulse. When this happens, you need to find Afton on one of the three monitors in your chamber and hit the green button next to it to burn him. If he successfully corrupts Freddy, the animatronic will become hostile to you, so you'll have to be quick.

While this is a fairly straightforward task, you won't be alone in the chamber. All three main animatronics will pop their heads in and you'll have to deal with the creepy Funtime Freddy blob you saw outside, making this much more complicated. In all honesty, how easy you find this fight will entirely come down to how lucky you are.

Sometimes, Afton will only send out the three animatronics once, meaning you won't need to worry about them in the second phase of the fight. Other times, he'll randomly switch from phase 1 to phase 2, catching you off guard or when your doors have very little charge left. In other words, this fight can be a pain, but here's how to fend off every single threat while going head to head with Afton.

Phase 1

If Afton's playing fair, the first phase of the fight will be against Chica, Monty and Roxy in a random order. Watch the monitors closely and burn Afton until you hear Freddy call out the name of one of the three animatronics.

If you keep an eye on him, you should be able to track where Afton is going to be. He'll always wait at the middle monitor after he's been burned using the left or right monitors and will telegraph which room he intends to move to. If he walks up on the middle monitor, he's heading to the left monitor. If he moves down on the middle monitor, he's heading to the right monitor.

As for the unwanted guests, if Freddy says Chica is on the way, look down both the corridors until you see her. Wait until she gets close to you and then lock the door on her. She'll bang on the door for a few seconds and then head back down the hallway. Once she's halfway back, unlock the door and return to the monitors.

Once you hear "watch the vents," run to the vent next to the middle monitor and lock it down. You'll hear Monty approach, bang on the vents and leave, meaning you're safe. Unlock the vent and return to the monitors.

If Roxy is the one to approach you, things can be a little more finicky. You'll be able to hear her crying, so watch Afton on the monitors until you can hear her cries right next to you. Make sure Afton isn't going to corrupt Freddy, then hop in just as Roxy enters the room. You'll want to face her and use Chica's voicebox to scare her away.

This can be annoying, as Freddy will frequently run out of power or eject you during the encounter (it's quite buggy), so make sure you use the voicebox as fast as possible. Roxy will run from the room and you can turn your attention back to Afton.

You won't be able to use the doors to fend of Roxy, so don't waste the power. She'll just exhaust it quickly, meaning you won't have any saved if Chica decides to attack you now or during Phase 2.

Phase 2

If all goes to plan, phase 2 will mostly be about endurance. Unless Afton reverts to phase 1, nothing will come after you unless Freddy is successfully corrupted. You'll hear a rumbling below the chamber and then tentacles will begin erupting from the floor and ceiling. These will kill you if you get too close, so you'll want to stick to the corners and continue to pursue Afton as he moves between cameras.

The best tactic here is to crouch next to the middle monitor. Watch Afton until he tries to corrupt Freddy, moves up, or move down. If he tries to corrupt Freddy, creep towards the button and press it while keeping out of reach of the tentacles.

If he moves down, you'll want to sneak around to the right monitor. If he moves up, call Freddy and use him to navigate to the monitor on the left. You can make it over to the left monitor without Freddy, but you're invincible while inside him, and seeing as the left monitor is the hardest to get to without being snagged by a tentacle, it's a huge help. Keep burning Afton when the opportunity arises.

After pressing a button on the left or right terminal, return to the middle terminal. Afton will always go back there after being burned and telegraph where he's going next. You'll know if the game's about to switch back to phase 1 again because all the tentacles will disappear.

Burn Afton enough and the fight will cut to a cinematic, officially concluding both the battle and the game. Congratulations! you've escaped the Pizzaplex and put a stop to Afton's crimes. At least, for now...
