    UPDATE: Thanks to 'General Wizzard' for confirming, you can lock the Marines behind the 1st or last doors by playing coop and having your partner teleport you forwards and still get the achievement.. makes it much easier!

    UPDATE 2: I just did this with two friends(Nov 1, '15); What we did was go until we met the first marines, then advanced a little to the next enemies trying to figure out who the Marines were following. Turned out to not be the host. The person they were following stayed back with the Marines who didn't budge at all, and the other two of us continued, cleared out the rest of the first area, and teleported him through the door. Achievement popped for both of them first try! (It was on Easy, no skulls)

    ---------------------------------------------------
    This achievement can be rather tricky, simply because the Marines like to get themselves killed by going out into fire. I highly recommend doing this with more than one person in coop, and on EASY!

    You can have one person hang back and keep the Marines from running forwards into the kill zones as they die in about one or two Carbine shots. However, if you do this, you run the risk of having whoever is in the lead teleport you forwards past a closed door and into a checkpoint, so make sure you brings the Marines forwards to each gate that opens and closes.

    However, we did confirm that you don't have to bring the Marines through the LAST door that opens and closes. My partner RoboFailBoat teleported me through that door, when we had only one Marine left, the Marine was behind that door and we got the achievement!

    Could someone please try teleporting past the first door and trapping Marines behind the first door and see if that counts for Marines alive--if it works like that, it makes this EXTREMELY easy!! Please let me know if it works! Thanks for testing and confirming it works for the first door 'General Wizzard'! toast

    MyNamelsNotJohnI was able to do this solo, kept the two initial marines alive until the big fight in the courtyard and at that point you just want to try to kill everything quick as possible. As soon as you walk through the door you want to focus on the jackals/brutes with carbines because they seem to kill the marines very quickly as mentioned in the solution. After that just kill the brutes and pick off the grunts.

    Ideally you want everyone else dead before the hunters come in and at that point just take them out fast as can be. I think I had 3 or 4 marines alive by the time the hunters came in and finished with only one remaining but that was of course enough. And it probably goes without mentioning but you can always reload the checkpoint before the courtyard fight if you fail and try again before going to the last section with Dare's drop pod.

    The S bot 9000Did it solo with one marine left! He stayed behind in the area where the hunters spawned and after trying to persuade him with some pushing I ended up just going forward and killing the 3 grunts around the pod!

    BadDogg55I plugged in 2 controllers, the main and secondary. Turned on Tilt and Grunt B-day Party. With the main controller I killed all the enemies right after spawn. Then went to the alley where the 2 marines come out of hiding, stopped at the beginning of the alley with the marines, they follow the main controller. Went to the secondary controller and caught up to where the main controller was at the alley, killed the 6-8 brutes. Left the main controller in the alley with the marines and speed ran through the rest of the mission without killing anything. Got to the end where the capsule is, killed the 3 grunts then ended the mission and the chievo popped.

    I ran through the level without killing pretty much anything except for 1 brute that got in my way near the end (right before the hunters). Jumped down towards the end of the level and killed the 3 grunts and ended the level. Playing on easy with the Tilt skull on, just run the way you would for a speedrun ignoring most enemies. The 3 grunts at the end I think you have to kill but try not to stop moving ever. Got it first try.

    Remember to put tilt skull on.

    This was pretty easy. I plugged in a second controller and started level. With my main controller i ran through the level never killing anything and made it to the end. My second controller was pulled forward twice and as soon as i ended the level the achievement unlocked.
