    Mission: Cairo Station
    Difficulty: Legendary (to spawn enough enemies)
    Skulls: Scarab

    Early in the mission you will come to a hangar that is being breached by enemies. Shoot at the tube they are coming in. The first wave of enemies will get stuck in the geometry. Once the second wave of enemies comes in, they will get pushed out. That's when you want to start shooting again. Since they are not in the Mission area yet, it counts as a stealth kill and the achievement will pop.

    KungFuMonk3yFebruary 2021 This worked like a charm! I walked in that area and opened fire and got it in like 3 seconds. AngryBob4213 you may want to try clearing your cache on xbox and see if resetting the game helps you.

    iamfleetingYep, this method still worked for me. I didn't have to wait for a second wave though, I unloaded when I saw the first one and it popped when that initial batch died.

    Jacky315Can confirm it worked as of today. By far the easiest and fastest method for this achievement

    Load up the level High Charity. There's a section right after you kill a few brutes that has a Covenant sniper rifle by a jackal at the bottom of the ramp before it ramps back up, then right after this it opens into a much larger area. When you open this door there's a bridge that opens up for you, but don't cross it yet. There are a bunch of flood across the way on a platform, and a bunch of bugs show up to fight them. Take out you're sniper rifle and wait until the bugs have engaged the flood and start taking them out.

    You'll need 7 kills in a row, so don't miss. If you do miss, there is another pack of bugs that fly in after the first are down. You can also just reload you're checkpoint. Your checkpoint should be right about when you open that door to go kill the bugs.

    Also I wouldn't try killing the flood with your sniper rifle to continue a kill streak, they will typically survive a shot or two.

    I found this area much better than the spot in Regret, because when I tried to do it in that level, the platform moving gave me another checkpoint and kind of screwed me over. Here you can take as much time as you want to get this achievement as long as you keep reloading your checkpoint. It's also not too far into the level, there are like just a few fights before you get to this spot, and if you do it on easy I'd say it won't take more than 5 minutes to get this achievement.

    I find the easiest place is in the mission "Gravemind" on any difficulty (no skulls required).

    At the point where Cortana drops you into a prison cell, with locked up Marines, behind a Brute looking the other way, melee him in the back, proceed to carefully melee the 5 sleeping grunts on the same level, sticking to the walls so the Jackals in the level beneath you don't spot you.

    Once you kill the last grunt, drop down one the jackal begins walking in the opposite direction of where you plan to drop. Melee the Jackal or the achievement.

    Ereaser NLOn Legendary there is 2 brutes at the bottom of the lift. If you punch one, the other gets alerted.

    Lorenzo El DuceDid it on normal. When you release the second group of prisoners you will have 1 brute, 4 sleeping grunts, and the two jackels outside the door

    AngryBob4213This just doesn't work. The second I touch a grunt the rest all wake up. No idea why, not near the Jackal at all. Super frustrating seeing people on youtube and whatever killing them no problem. Also the grunts dont drop in 1 hit for some reason
