Locked Doors

Upon defeating Porkpatch you’ll gain a Key. The Key allows you to open doors. Logically! Now you just need to find the doors. They’re spread throughout Animatronica, and will require a fair bit of backtracking and exploration to locate. Be prepared to go through most of the game again to find ‘em all.

The locked doors are in the following locations:
  • The first lock is in the northeast of Fazbear Hills, just outside town.
  • The second lock is in the southwest corner of Dusting Fields. You’ll need to face a boss to get through here.
Snowcone makes an appearance in FNaF World.
Chill out. Or... something. (I'm tired.)

Looks like Bouncer, isn’t. Snowcone has attack power almost comparable to Porkpatch, and can quickly dispatch your team with normal attacks and Snowball if you don’t debuff him. Jumpscare is particularly dangerous here, stalling you and giving Snowcone a chance to kill one or two members of your team. Swap out for your second team whenever the first gets stunned, armour up, and use powerful, attacking Bytes - such as the ever-awesome BossDrain Bytes - to bring Snowcone low. If you’re really unlucky he’ll start using Esc Key to insta-kill multiple characters, but this doesn’t happen very often. 

He’s guarding a button. Push it. Yay!
  • The third lock is in Choppy’s Woods, though it’s accessible only from Lilygear Lake. Surf north from the entrance of Lilygear and check the trees to the south as you walk west. There’s… nothing behind it? Okay, well, unlock it if you want, I guess. (In truth, this lock is only useful if you've gotten all of the clocks, in which case you'll find a portal to one of the endings in the tiny space between the trees.)
  • The fourth lock is in the far northeast of Lilygear Lake. It is, of course, guarded by an invisible enemy.
He's not just a goon. He's a Supergoon.

Harsh. This thing can hit for upwards of 500 points of damage, which is probably enough to kill a character in a single hit. It will also summon Hot Cheese to chew away at your team’s health. Throw up buffs and debuffs, and let BossDrain Bytes sap its health. Probably the physically strongest boss you’ve fought so far, but if you can delay it a bit - debuffs and Jumpscare work nicely - it’s not that bad.
  • The fifth lock is in Deep-Metal Mine. Head east from the entrance and explore to the northeast to find the lock. The button beyond looks unguarded, but…
Overclock, from FNaF World.
Nasty, nasty, nasty.

This battle is awful. Overclock doesn’t hit very hard, considering its size, but it uses Unscrew. All. The. TIME. ARGH. It’s also really fast, and can decimate your team in an awful hurry even with its physical strikes. Healing away its normal attacks is okay, but you’re better off going on an immediate offensive with all characters and doing what you can to decimate the bastard’s health in a hurry. Debuffs are essential for slowing it down a touch and making its attacks more manageable, Jumpscare is handy for stunning Overclock, and the BossDrain Bytes will make the damaging process much easier. Gift Boxes is always useful, so long as the gift-giver isn't murdered horribly.
  • In addiction to the locks detailed above, there's a sixth, secret lock, hidden in darkness. You'll find it in Mysterious Mine, via the Lilygear Lake entrance in the far north of the world map. Head southwest through the Mine until you're plunged into darkness, then walk north, pressing along the edge of the map. There's a small, hidden chamber in here that leads to a hidden boss.
Chipper. He's back. And he's pissed.

Chipper's Revenge

Yikes. Chipper's Revenge is perhaps the most versatile boss in the game, despite how he starts out. Normally Chipper uses a physical attack that will decimate anyone he hits (5,000 + points of damage, anybody?), but as the fight wears on he'll start throwing in a bunch of other attacks: Toxic Bite, 4th Wall, Waterhose, Esc Key... all are quite painful, and all of them target your whole crew rather than just one character. Chipper also has a ridiculous amount of health, more, I think, than anything else in FNaF World.

Because Chipper hits so hard there's not much point trying to heal your characters, so it's better to go whole-hog and use Gift Boxes every time it comes up. One character with Mimic Ball active may be able to handle this workload, but two is overall safer. Your other two characters can either focus on debuffing Chipper or just knocking the crap out of him, but I suggest that at least one of them should use Jumpscare to stun him for a few seconds, earning you more of a reprieve to heal your dudes with Gift Boxes. Coupling Jumpscare with Mimic Ball will roughly double the amount of time you have to work hassle-free.

As for damage? Bytes. Glorious Bytes. Let the BossDrain and UFO Bytes do most of the work. The Fan can also contribute a fair amount of pain, assuming you've recruited all of the animatronics.

This is perhaps the hardest boss in the game, and I recommend taking on the final boss of Hard Mode before trying to tackle Chipper's Revenge. The tactics suggested here are quite similar, but are slightly less taxing in that fight since the final boss doesn't have as much health. That said, beating Chipper's Revenge will earn you an ending, so in a sense he is the final boss! Yay!

- Enough secrecy. That’s all of the locks. You now have one last destination, and that's Pinwheel Circus. Head back there via Jump and you’ll find that the glowing gates near the Lolbit’s Byte Store have vanished. A boss waits beyond.

Security, the possible final boss of FNaF World.
Nasty owl is nasty.

This boss is both easy and ridiculous. Security is strong enough that it typically destroys characters in a single hit. What’s more, it has a a multiple-hitting orb attack called Alarm that does 9,999 damage to five characters, and will pretty much wipe your party. Great. That said, Security is niiiiiice and sloooooow, giving you lots of time to set up. 

Debuff and Jumpscare Security to delay its turns as much as possible, then deploy an animatronic with the move Neon Wall (Endo 02 or Endoplush) and use the Wall to block that apocalyptic orb attack. Re-cast Wall as necessary. For safety purposes, you should probably put your Endo in the inactive team, and deploy it only when Neon Wall goes down. This will save it from Security’s other attacks, which ignore Neon Wall completely. (You can also just use both Endos - just make sure they’re in separate teams.) The BossDrain Bytes will make chewing away Security’s health much easier, though even with all three deployed it will take a while. 

RXQ is an absolutely amazing animatronic to bring along, if you're having trouble, as he can use Gift Boxes to revive dead characters and Mimic Ball to just generally copy everything everyone else is doing. Great way to keep Neon Wall fresh. If you don't have him, wander around Circus Funhouse for a while.

- Upon defeating Security you’ll gain access to its tent. If you go through on Normal your game will come to an abrupt end. If you’re playing on Hard Mode, however…

Scott Cawthon, supreme overlord.
You know you've wanted a piece of that avatar.
Scott Cawthon

Yes, it’s him. If you know his games, you know it’s him.

Cawthon is a brutal opponent. He has three attacks: a normal, physical attack which will probably kill a character, 4th Wall, which hits everyone for over 600 points of damage (usually an insta-kill), and Alarm, which is identical to the attack used by Security, albeit hitting only three times instead of five. He's pretty fast, so these moves come zipping in at you at great speeds. Prepare yourself for a rough time.

Cawthon doesn't have ridiculous amounts of health - though, admittedly, you can't see his health bar - but he can kill you so quickly that his health almost doesn't matter. It's easier to survive this battle by focusing on your own health. Put two characters in your party with Gift Boxes and have them spam the move constantly. (If you don't have the Auto: Mimic Chip in play, RXQ's Mimic Ball will add another layer of Gift Boxes each time you use the move, plus it has Gift Boxes itself.) One of the Endos should throw up Neon Wall to deal with Alarm while your fourth member can either attack or debuff Cawthon. The majority of your damage will probably come from your Bytes, of which I recommend the top two BossDrains and the top two UFOs. At that point it's just a waiting game until he goes down.

(As some people in the comments point out, it's also possible to kill Cawthon with auto-kill attacks like Unscrew. The chances of one sticking appear to be really low, though - it took me five minutes of Unscrews and Bytes to take him down. Still, it's an option.)

Huzzah! You win! Enjoy one of the endings! It's... bittersweet, in a way.

Be warned! If you lose to 4th Wall you’ll be shot back to Fazbear Hills, as usual. Problem is, you’ll need to fight Security again to re-access the final boss. It’s a good way to build experience and Tokens, but Security takes long enough for this to be a nuisance.
