Welcome to Alien: Isolation, a first person, survival horror game based on the Alien franchise and developed by Creative Assembly. You play as Amanda Ripley, Ellen Ripley’s daughter, as you traverse through the decaying Sevastopol Space Station trying to survive as one of the universes deadliest specimens is out to kill you.
The general gameplay in this game is highly stealth focused. If you try and go all Rambo you will die many, many times so stealth and hiding in closets is the name of the game. You do get some tools to help you on you path but none of them are a massive help and you can get through large parts of the game without using them. The item you will be crafting and using the most will be the medkit anyway. The trophy list is a fairly simple one, from story related trophies to miscellaneous trophies for crafting and using certain items. If you are thorough on your first playthrough you should get most of the trophies then. The main trophies to look out for are Survivor, Mercy or Prudence? and One Shot. These are for beating the game on hard, without killing any humans and without dying respectively. They don't all have to be done together and I wouldn't recommend it either. Mercy or Prudence? and One Shot are missable if you mess up but you can utilize the reload save technique to work around it.
If you choose to play the game on Hard first as I recommend you can knock Survivor and Mercy or Prudence? out in one run which just leaves One Shot to be done on Easy since after beating the game on the hardest difficulty you should have the knowledge of what to do on easy without dying. Aside from this all you may need to worry about is the collectibles which can be gotten via mission select.
Step 1: First playthrough on Hard without killing any humans
For your first playthrough I suggest to just do it on Hard since this way you will already know the best routes to use to avoid enemies so you won't die on your second playthrough on easy. There isn’t much difference between difficulties since on early levels no matter what difficulty once the Alien sees you, you are dead. The only other differences are that Androids and Humans have better senses and do more damage but since you will be trying to avoid them this shouldn't be an issue.
During this Step you will also focus on not killing any humans since when you do your no deaths run you don't have to worry about killing humans. At the same time you should focus on picking up any of the collectibles you come across i.e. ID Tags, Nostromo Logs and Archive Logs. This way the next step will not take as long. You should also unlock many of the miscellaneous trophies on your first playthrough.
After this step you should unlock:
Welcome to Sevastopol
A Perfect Organism
A Record of Disaster
Build to Survive
A Hunt Begins
You Shouldn't Be There.
She's in the Vents...
I Admire its Purity
How Do You Feel?

Step 2: Clean up and Collectibles
During this Step I suggest that you finish picking up any missing collectibles you haven’t gotten yet so you don't have to worry about them for your no deaths run and to clean up any miscellaneousness trophies that aren't "do this part without dying" trophies. You can turn the difficulty down while cleaning up these trophies and if you haven't been killed by the Alien 100 times for 100 Times Too Many you can die repeatedly in Survivor Mode until it pops since for the next Step you don't plan on dying. After this Step you should have:
Just out of Reach
Not a Scratch
My Turn Now
100 Times Too Many
Step 3: No Deaths/One shot run
This Step is dedicated to beating the game without dying. Start a new game on easy and any time you know you are about to die, pause and reload current save and if you happen to die just reload previous save and you should be fine. You will also unlock the trophies for not dying during certain objectives along the way.
After this Step you should have:
Hide. Run. Survive.
Mind Your Step
