Call of duty black ops cold war the red door

This is a pretty easy achievement, all you have to do is pay attention to what Adler, who is narrating to you what happened, is saying.

Just go through the red door the first time you see it and it starts the progress to the achievement.

You will find yourself once again in the rice paddy fields only with a bow and silenced pistol this time. Make your way through here but you don't have to kill everyone, just get through it however you wish.
Once you are through the red door will appear again, go through it and you are presented with 2 slide projectors. Use both of these to make a picture of another red door, walk towards the door and go through it again.

This puts you in a bunker again, walk forward and the screen goes bright white, and then puts you back in the helicopter. You are in the paddy fields again but with a grenade launcher and an AR this time. Fight through here once again. Once in the jungle, follow the instructions to go left again, and there will be 3 snipers in tree nests above the river, take them out and move across the river. Cross the bridge with the frozen in time firefight happening. Follow the path left when you get across as you can't go towards the village this time. Drop down and take out the enemies, you will very soon after be given a napalm strike to use. Follow to the right and toward where you just napalmed to find the next door to go through.

Turn around in the next room (you will be told the door was stuck) and continue behind you instead and enter the door once again, follow the route even more and go through again after the slow down motion section. In this area you will be running in circles (or squares to be exact) just keep going around and you will come to a point where as you move on you will start floating off the floor more and more, turn around and go back the way you came, you will see the red door and some position back where you came from, yep you guessed it, go through it. Once again head forward and go through the red door that is left in front of you.
Back inside a war room bunker again now, almost finished guys. Access the computer behind the board Perseus was looking at, choose whatever options you wish as I'm not sure if it makes a difference.

Now here is the final bit, starting again in the helicopter, this time the firefight will be bypassed by Adler with a fast forward time skip. You will be left at the ruins with the red door in front of you. DO NOT go through it now, instead go either left or right (I went right) and watch where you are walking, the vision will now start putting red doors in front of you, so just keep walking around them. It will eventually place you in a room with the door in front of you and the achievement should pop here as it did for me.

If I have put anything that appears wrong later, let me know guys.
