How to unlock the Knight in White Assassination achievement in Halo 4 - Definitive Guide

There are other methods but this is how we did it

Spartan Ops - Episode 1 Chapter 4

-Proceed to the 1st Sky map, and activate and clear out the enemies in that area

-On your way around the corner to the objective and Knight will spawn in front of you, use the corner for cover and wait till it turns its back to you

-Sneak up and HOLD THE BUTTON YOU USE TO MELEE (RB is the Default button) - Achievement unlocked!!

Worked perfect. Used my radar to tell when he had turned his back and then bam. Another way is to get lucky and run behind one in co-op whilst he shoots a team mate but this is a much easier, sure fire way.

Using Promethian vision really helps out.

That is a good idea to see when he has turned easier! I was addicted to using the jet pack, we were searching for easter eggs so i used the JP to get high, out of map etc

I'd recommend maybe mentioning holding the melee button instead of "HOLD RB", since melee isn't RB for everyone.

This was a pain in the ass on legendary. I couldn't sneak up on them even with active camo without them always spotting me. Finally I just started charging at them hoping to get behind one of them and eventually got it at the end of Chapter 5. I just couldn't get it to work on Chapter 4.

just want to say it's an excellent guide, however I got it random during a firefight - went up to a knight and attempted to punch him, counted as an assasination. Not bad

Yeah there are plenty of different methods. I had a few different ones over the course of playing. Did record them but this is the one that seemed simplest. Not including pure luck

Just want to add that this Cheevo is buggy. It unlocked for me the third time I did it.

For non-native English speaker, sneak up = press cn_B once to walk silently and get close to the enemy.

The other solutions posted so far contain pretty slick ways on how to assassinate a Promethean Knight. I'd like to share my method of nailing this achievement using Episode 1, Chapter 5, solo, on Easy difficulty without Holograms or Stealth Camo'.

The best chapter to get this achievement is on Episode 1, Chapter 4. I highly recommend making a custom loadout with prometheus vision for this achievement. After completing the first mini objective (activating the switch) you start going back to where you came from and a white knight will spawn around the corner. You will be informed by a voiceover. At this point, crouch around the corner and use prometheus vision to watch the knight walk back and forth, as he turns his back towards you, run up to him, and hold RB to preform an assassination, unlocking the achievement.

Knights appear during 4th and 5th mission of the Spartan Ops Episode I. You can use hologram or your friend as a distraction. Get behind Knight, then press and hold melee button.

This achievement also unlocks a special Custom avatar item, a Silver Promethian Knight helmet for your Xbox live avatar. the best way to get this item is to have a friend help you distract the Knight. My solution needs to be 25 characters long so that is why I am writing so much in my comment. Lol.

Short and sweet way to do this with a friend.

1. Load up any map with Promethean knights we used Episode 4 Chapter 2 Rally Point on Two Giants.
2. Designate your friend as the bait and you as the assassin or vice versa.
3. Make sure a Knight is alone as its easier this way.
4. Make your friend distract it while you hold down RB for the kill.

Video below showing how we worked together, you can do this anywhere but this is how and where we got it done! Good luck!

Infinity Multiplayer :: Spartan Ops related. Online Required. Can be obtained on Easy+.
When behind a Knight, press and hold  to perform an assassination either Solo or Cooperatively.

You can find a Promethean Knight within Episode 1: Infinity • Chapter 4: Sacred. See Best Chapters for Boosting Enemy Commendations for other Episodes/Chapters with Knights.

It's recommended making a custom loadout with prometheus vision for this achievement.
