How to unlock the Mind Your Step achievement in Alien: Isolation - Definitive Guide
If any of the Aliens spot you, try to get the alien to retreat using a flamethrower or Molotov, if they are about to kill you, then quickly load your current save. You will also need to look out for the facehuggers, which you will also need to burn or they will kill you instantly, you should be able to hear the squealing before they attack you.
I recommend you watch the video below, so you can see the quickest routes to complete the objectives and when you will be attacked by the facehuggers.
chapter 14. There you must go through the Nest without dying.
BEWARE - If you get killed you'll not be able to get the achievement.
I recomend you to save the game 2 times or load always the previous game or
update the game to the cloud or in a USB. If you die load the saved
game and you'll be able to continue as if you didn't die.
I'd recommend simply watching the video for the ideal route and molly-prep
There are 3 scripted Aliens that will fuck off after a couple seconds of waiting and don't return. You can kill the first 3 Facehuggers just fine, but the one that comes running up to you while you go deeper into the nest usually starts the hunt for the "regular" Alien, if you kill it. To avoid this, immediately go into the small locker to despawn him instead.
That way you prevent setting off the Alien and won't have to deal with any other than the scripted ones and the enraged one that spawns in the entrance-room after prepping the nuke.
This trophy can be gotten during mission 14 when you enter the reactor maintenance to overcharge the Alpha and Beta cores. I will put the rest of the description in spoilers to avoid spoiling it on you.
Like all the other sections don't run, because that will draw the attention of the alien so use your flamethrower to fend off the Aliens and kill any Facehuggers. If you don’t kill a Facehugger then it's an instant death as you are unlikely going to have time to reload your current save. If you die via a Facehugger then reload your previous save instead, you will be sent back further but you will still be able get the trophy.
If you wish you can also back up your save to the cloud so you don't have to replay large sections so if you die to a facehugger you can just use the save you backed up. Also burn any eggs you see in case a Facehugger comes out. After you escape the area and ascend the elevator the trophy should pop.
