How to unlock the Dumb Luck achievement in Damnation - Definitive Guide

I have added a video to the solution but have given text form too for those that can't play the video. (Sorry about the quality too).
Make your way through the chapter and you will eventually get to a ladder taking you down into the sewers after a lot of building traversing.
Head down the sewers and back out the other side (you will get a save point whilst down there which is great for retrying if needed).
Once you have the save point, exit the game and then sign a second profile in. Now, select split screen campaign and continue from where you left off. Make sure you are in control of the profile you wish to earn the achievement on and then climb the ladder out of the sewers.
Pick up a mine if needed and then head towards the pillar just behind the one in front of you when you get out of the sewers. You will want to wall jump up onto the top of the raised area and then jump across onto the right hand platform you see next to the machine gun turret.
Once you are on here, it will spawn the second character right out in the open - perfect bait! Now, just wait for the five creatures to head towards the second profile and then throw a mine (hold LT + tap Y). You want to time it just before they all get there and you may have to shoot it to make it explode.
You may occasionally find that one of the creatures gets held up or moves away just as it explodes but as you have a checkpoint really nearby you can just load the last one and run through it again. With the right timing in throwing the mine, you will pop this achievement.
If you can't get it with a grenade than go to the unlockables menu and enter LockNLoad to unlock the ability to choose what weapons you want than simply choose arrow rifle and it should make getting this achievement a little easier.
The best way to do this is to play in co-op.
1. Let the person that isn't getting the achievement run ahead and get the attention of as many enemies as possible.
2. Let them kill that person. The enemies should them gather around the downed player. After you're downed you can see the people vaguely, so count them until you see more than five. Then tell the other player to go.
3. The player getting the achievement them catches up and throws a trip mine or shoots the explosive arrow gun.
This trophy is very hard to get playing solo. For an explosion to occur you need to either shoot an explosive barrel or throw a trip mine and press to detonate it at the precise time enough enemies are in range. There are only a couple of places in the game where 5 enemies will group together and stay there long enough for this to work and both are in Terra Verte. One will be during a sequence where Yakecan will comment on the tragic state of overdosed PSI serum addicts, the other is when you surface from the sewers before entering the Governors HQ. On both occasions you need to stay on higher ground and let Yakecan be the bait. The trouble with this though is she tends to kill them before 5 can surround her so this is going to be a case of repeating the actions until you get lucky.
The most reliable method is to obtain this in splitscreen mode in exactly the same locations but this time pick up controller 2 and have them stand there in the open while you use the First controller to position yourself properly for a well-timed trip mine. Here's a video of the second location using this exact method courtesy of sunnygrg:
