Call of Duty: Modern Warfare 3 Achievements

Serrated Edge

Finish a Juggernaut with a knife in Special Ops.  

A Juggernaut will spawn at wave 10 of a Survival game. The best thing to have on you when one is about is a lot of ammo and few flashbangs.

Start out by making sure it's just you and the Juggernaut left. Now work around him and just keep hitting him with bullets. To be safe use about 2 clips then stop. From here, find something you can run around so you can get behind him. Throw a flash bang, get behind him and start slashing at him with your knife.

If he's taking a fair few slashes, put some more bullets in him. Hopefully after a few slashes of your knife you'll get the kill and achievement.

This one is actually pretty easy!
All you have to do is keep running around in a circle around the Juggernaut, knifing along the way.
Since you are running around him, he has a difficult time actually landing bullets, along with the knifing, it throws him off of his game.
(I weakened him first with a few flash bangs and the MP5 and finished with about 8 or more knife attacks.)

The Juggernaut in that picture looks like a legit beast.

Check out the videos under "Spotlight" for MW3. I can't remember the name of the video but one of them shows you EXACTLY how to get this achievement plus the one where you have to shoot down two choppers in Spec Ops without taking any damage!

Very Easy, escpecially if you play with another human.
If alone do it so: Frag him with 4 C4 in one place then throw a flashbang try to get behind him and knife him to death.

I got this by accident lol

Was using an LMG, on survival mode, didn't see him coming, kept firing and running back, then i ran out of ammo, so as a last resort i ran up to him shouted 'F*ck*ng die!!!', knifed him, he died and i got this achievement lol

I picked up a sniper rifle and thought I would be close enough to run up for some knife runs.

Here is what i did w/ partner! The one trying to get achievement should go to the jauggernaut and the person who isn't just keep flashing him! it works best on easy difficulty!

I got this one while playing solo.
heres what i did, i had a team of riot shield guys to back me up, and while the jugg focused on them i went behind him and just started knifing. when he turned to shoot me i ran away and came back and did the same thing over and over. granted it may have been a fluk i got the final hit in on him and got the achievement.

This was fun. I actually got this totally by accident. My advice is to just have fun, it unlikely you'll get it if you stress to much. It's a fluke, so just keep trying. Oh and And obviously it's easier to knife after a flashbang.

Comment #23 by sanctuaryforall
Thursday, November 24, 2011 @ 09:01:40 PM

I also got this solo, on a level with two jugganauts. I don't think there is any kind of trick to it, and I don't think you need anything fancy.

I did 5 C4 and one clip from a p90 then flashbang then move in for the knife.
Hope this helps =)

i found this one pretty easy, i just went survival in the dome, and shot him till he was running, then knifed him and he died

2 flashbangs a couple shots with the shotgun and then started to knife him like a thanksgiving turkey. Took a couple of tries.

So easy, my friend was pumpin' him full of lead, and I just stole his kill for fun and beep-bop easy 15 G.

Not as tricky as I thought it would be. Two of us both got it in the same game. Mine was a combination of walking him through claymores, flashbangs and my riot squad distracting him!

This one is super easy. First load up the map dome and wait to wave 9 then kill all the dudes so the juggernaught is left then empty two to four magazines into him but i use three to be sure then flash the juggernaught and knife and repeat till he dies.

This is pretty easy to do if you only have a single riot shield juggernaut left on Survival. Just keep sprinting around him in circles stabbing him in the back. Takes quite a few swings but it's simple.
