    mo0ohammed19988If you're having problem unlocking it the normal way try this..
    For me the first group wasn't enough for it to unlock.after the first group the combat music starts and i stayed in the same place zooming at the side of the second turret and start killing the enemies as soon as i see them.There was 1 elite.. 2 jackals.. 6 grunts after the first group and it's unlocked immediately after killing the last jackal.
    -stay on your place after the combat music starts so the marines stay near you giving you a chance to kill the enemies before they start fighting together.
    -played on easy / 0 skulls
    -I missed multiple shots and that was completely fine as long as they didn't noticed you. don't double shot them(it's preferable to play on easy so you can 1 shot them).

    DoomScottIt is glitched on co-op for me. Did it successfully several times and nothing. Did it single player and got it first time.

    Now that the Bandanna skull is available to everyone, I found the best way was to turn on Bandanna, Boom, and Grunt Funeral Party on Easy. This way, you can do it without ever needing to fire the sniper rifle.

    Switch to old graphics with cn_back, as the new textures occasionally don't behave well with the old textures. From the place you spawn, angle your throws upward to barely clear over the edge. Once it's doing this, slowly pan left and right to carpet bomb the area. This gets rid of the enemies on the far side of the area. These are the enemies easily sniped, so if that's not the problem, take them out from the mouth of the area, by the tree.

    The enemies close to the near wall were the problematic ones for me. You'll want to be closer to the wall with a higher arc on the grenades to get them just over the side to get the rest of them. Once you've got that high arc, it's the same process; pan left and right to carpet bomb closer to the new wall. For reference, back in new graphics, there's two darker leafy plants by the path before heading in; that's where I was standing when I got the rest of them.

    The achievement pops immediately after the last kill. If you've done all this and the marines charge forward to meet the enemy with a music change, check to see if it isn't stuck in "Done! Unlocking..." as that indicates you've completed the first area.

    geniusboy91I also threw a quick grenade at the beginning to kill all the marines. I kept chucking grenades until the music came on, but even after the music, there was still one more grunt that had not been killed. Killed him and achievement popped. DO NOT ASSUME MUSIC MEANS YOU'RE DONE.

    Assassin CorvoCame here looking for clarification (ie difficuly/classic or anniv/what's detected etc.) Used this guide combined with sneaky snipery on Heroic in anniversay mode & i did miss a shot,the achievement popped as soon as i popped the sleeping grunt.

    KAW 24Fun alternative to sniping as per the original X360 achievement, although my first grenade didn't clear the edge and killed two marines - oops. redface

    Okay after having issues unlocking this achievement I messaged vexer6 the most recent person to unlock it. Here's what he said to do in order to unlock it, I would just add that you MUST have a physical copy of the game for this solution to work. I had to start the game for it to unlock, but hopefully it will help anyone else having issues too. Not sure why someones voting me down, I'm only trying to help, and credited the guy that told me a solution.

    "To get the achievement I uninstalled the game, took the console offline, then took the disc out and put it back in to get it to install from the disc. Then I loaded the game up, selected the Truth and Reconciliation mission and did the normal requirements for the cheevo, quit out of the game, put the console back online and then downloaded the patch for MCC and the achievement popped within a couple of minutes of the download starting(thankfully you don't have to wait for the entire patch to download it seems)I didn't even have to load up the game."
