  • I swear, I've done this about 100 times, tried it on EVERY difficulty, tried with and without skulls, and it NEVER unlocks. I don't even get detected, wtf am I doing wrong? I know I'm not getting detected because none of the enemies even look at me, then once they're all killed the music starts and the marines jump down as the elite comes around the corner, hell. I even just did it with that elite and the pack of grunts that follow him not seeing me.

  • the night vision on the sniper is useful if youre on the classic graphics and brightness is turned down

see all

  • What I've found is that they're more likely to detect you if you set them on alert from killing a target near them, so if you go in a pattern of just killing one at a time and then waiting between kills, you're more likely to get the achievement. it isn't a broken achievement, it's just that a lot of people think that they haven't been detected just because the enemies are running around, when really that's often detection behavior indicator for elites and jackals especially if they roll.

  • I've lost count how many times I've done this and haven't got the achievement

  • @timmie1013

    I'm having the same problem. This achievement is fucking broken.

  • got it, thanks! i was heading up the cliff too far. i did it on easy and used grunt funeral. don't think grunt funeral helped much but w/e

  • then on the next part, look down and there will be two or three grunts...kill them too but be careful, THEN thats should do it...if not...walk into the open a bit, then run back when u see more enemies coming...hide again and there will be an elite, a grunt and a jackal, kill these too.

  • I done this achievement this morning...after about 20 goes. You have to stay AWAY from the ledge or they will see you...when you first get to the canyon entrance, in front there will be a grunt o nthe turret, or they will be around it also, kill them, then 2 jackals will walk by the turret..kill them too. THEN...a blue elite will walk by the turret also...kill him...THEN..sneak onto the ledge a TINYYY bit untill you see the far end gunner, be careful he has good vision, kill him. then.
