How to unlock the Knightfall achievement in Batman: Arkham Knight - Definitive Guide

To get this achievement you will need to get all most wanted missions done, That includes you getting all riddler trophies, I know fun right?

Once you have 8 most wanted prisoners you'll start the first part of this achievement, Then to unlock the achievement you have to get all 12, Along with getting all 12 you get the full ending to the game which is honestly insane.

Just a note: if Azrael attempts to kill Batman instead of breaking the sword, he would be taken to GCPD as well, making the max no. of most wanted criminals 12 instead of 11.

Also if anyone is scared that after you do the knight fall protocol you go into a point of no return that's false. The game will just put you back at the bat signal after the cut sense.

EDIT: Don't forget about Death stroke, He comes after you do all the bombs and checkpoints and watchtowers. The guide for him can be found here if you're having any trouble.

I am currently at 11/14 of Gotham's Most Wanted. And and my game says to Apprehend 1 more of Gotham's Most Wanted to activate the Knightfall protocol. I wonder if this achievement will unlock at 12/14

Oooh, Yea i get what you mean. There are 14 most wanted missions but only 12 most wanted criminals. Own the roads, the watchtower one and campaign for disarmament all lead up to death stroke.

So 14 missions 12 criminals. and only 11 if you let azrael go.

Yea, Sadly I'm at 12 of 14. I can initiate the Knightfall Protocol from the menu but it doesnt do anything, when I back out it tells me to select a mission. Is this an error or am I doing something wrong? I've tried initiating the protocol from a random place in gotham and standing in front of the bat signal on top of GCPD.

The achievement wont pop until you have every most wanted criminal locked up.
And about your problem odinhawke I have noo idea what went wrong. You should have been able to initiate it once you had 8 most wanted criminals locked up. But have you tried getting them all?

I was wondering, you are talking about a "good" ending. I have not completed the game yet, but does doing this before completing the main story give a different ending?

No, You'll get the normal ending at the end of the game then after you can do the nightfall protocol and its a way better ending.

I initiated the Knightfall Protocol with 96% completion. I watched the ending, watched the credits and didn't get the achievement. The achievement is for activating the knightfall protocol, not 100% completion. I did this without doing the riddles. I did knightfall but got no achievement. Has anyone else had this problem? I'm trying to get Xbox support to help but they're not doing much.

Hahaha, you have to get 100% completion. My guide is not incorrect. You are able to do the protocol with atleast 8 prisoners but you need all of them locked up. You're not bugged you just need to go and get the rest of your riddles and trophies bro.

Has anyone had a issue where they 100% complete the game and this achievement does not pop? I have beat everything and this achievement didn't pop as well as the one for locking the riddler in GCPD. However I got other achievements after not receiving these two.

j hews, this isn't unlocking for me either. Just the the 100 percent achievement is stuck. Everything else has unlocked (except for the car jumps, I'm stuck at 7/8). If I seriously have to do this all again...so SO pissed.

I think it's worth noting in this guide that the achievement text is misleading, as it will not necessarily unlock when initiating knightfall protocol.

The achievement didn't unlocked the first time I launched the protocol, so I restarted on the previous save, it didn't work. I use a Series S, so i force quited the game, restarted the console and launched the protocol again. The achievement finally popped when we *spoiler* see Vicky Vale.

There are 14 "Most Wanted" missions: The Line of Duty, The Perfect Crime, Riddler's Revenge, Occupy Gotham, Armored and Dangerous, Campaign for Disarmament, Creature of the Night, Gotham on Fire, Gunrunner, Heir to the Cowl, Two-Faced Bandit, Friend in Need, Own the Roads, and Lamb to the Slaughter. You only need 12 to initiate Knightfall and get the "bad" ending. If you complete all 14 and then initiate Knightfall, you get the "good" ending. Either way triggers the achievement.

^ Once you lock up EVERY villain, including Riddler, you'll get a message from Alfred that begins the full Protocol.

the achievement description is a little misleading. It should read as, "Lock up every supervillian and then initiate Knightfall protocol". You can start up the protocol at under 100% but the achievement won't pop unless you get full completion so you can view the "true" ending.

Any chance that we can update the listing to say that this is glitched? I just activated it yesterday and it didn't pop. The game autosaved with it being activated and I couldn't do it again. My back up save was back at 76% and loading it will remove my 100% save and New Game+. I don't know if I can be bothered to redo the end of the game for one achievement. If I had known it was glitched I would have been ready to force quit when it didn't pop.

This is achieved after you have completed the main storyline and then every single sidequest, that includes all 243 riddles and apprehending the Riddler.
Once you have locked up all major threats in Gotham you will be able to unlock Knightfall Protocol. The waypoint will direct you to the spotlight with the bat symbol atop the GCPD building and ask you to press cn_X to initiate.
Doing this will show you the full ending of the game and then unlock the Knightfall trophy for you.

A partial Knightfall won't count - in order for this cheevo to pop, EVERY base-game Most Wanted criminal must be captured.

After completing the main 7 Most Wanted side missions you will be prompted to initiate the Knightfall protocol. Doing so will award you with a partial ending scene, however it will not unlock the achievement. To unlock this achievement, along with the complete ending, you first need to obtain 100% completion in either your initial playthrough or your NG+ playthrough. This includes completing all the side missions in your log, even collecting all the Riddler Trophies and locking up the Riddler. Once you have 100% completion, head to the GCPD roof and initiate Knightfall protocol again to unlock the achievement.

Secret ending after completing the game 100%

(P.S. We need to put all the especially dangerous ones behind bars, and in order to put the Riddler in prison, you need to save the cat woman and collect 243 trophies)

Not all mysteries are revealed immediately. Towards the end of the story you will only be able to collect all the trophies. So if suddenly in some places you don’t see them, then this is not a glitch or a bug.

Completed everything except the riddler trophies (didn't collect any questions, never put the riddler in jail). I launched the crash protocol through the task menu without any problems, the credits started rolling, everything was fine.

And at the end the inscription: Arrest..... to open the full protocol

I don't know, maybe this was fixed with a patch. But I completed the game 81%, and did not complete all the additional tasks. And "Knightfall" is available to me.

You can start the “Knightfall” protocol by completing all the additional tasks without collecting all the riddle trophies, the inscription will open in the task menu to start the Knightfall protocol, but to get the achievement you need to collect all the riddle trophies, otherwise the protocol will not be complete and you will again be asked to complete the additional task

Game version 1.14. There is no way to start the protocol until I catch another one (the Riddler). Most likely, this happened because he did not kill Batman in the tower, but broke his sword, because Azrael was arrested during the attack.
