Walkthrough:
Step 1 - Complete the game once with Red Ending without using any Mirrors or Flares
First of all, trophies in this game do not unlock as soon as you fulfill the requirements for them. You must go to your room and sleep, which will save the game and only then you will unlock any trophies you’ve earned thus far.
When you start a new game you will be given two choices. Choose the first one to play on Normal Mode. Complete the game and do everything listed under Demolished Man to get the Red Ending. If you didn’t get the Red Ending, load your last save and keep doing stuff listed there until you get it.
This playthrough should take between 3-5 hours depending on your speed. Check your in-game map often and you shouldn’t have any problems. The Map shows you where to go, which ways you can take and can’t.
Do not use any Dusty Mirrors during this step. Dusty Mirrors act as teleporters in this game and return you back to your apartment. For the Grounded trophy, you must not use any of the mirrors. If you happen to use one, quit the game and continue from your last save.
Also you can’t use any more than 1 Rotting Meats, which is needed to get past the first enemy, or any Flares during this playthrough, which means you have to kill every single monster you face, if you have no other means to proceed. This will help you achieve "Red Ending" though, so it’s a good idea to kill any monsters you face anyway. Don't forget to shoot the Writhing Thing in the basement for Paranoid trophy and claim to know the Man in Blue when asked later on for Schizophrenic during this playthrough.
Don’t get upset if you can’t unlock any trophies, a majority of the trophies will unlock during next step(s).
Step 2 - Start a New Game on Expert Mode for White Ending
Once you complete the game, you can start your next playthrough, which acts essentially as New Game+. You won’t keep anything from your last playthrough but you will get extra items and have extra scenes.
Once you start the game choose to overwrite your save and when asked choose “I know my way around.” this time to start on Expert Mode. In Expert Mode, there will be no notifications and you will not be able to use any maps.
You also can’t use your handgun at all during this step. All enemies can be ignored, sneaked past or moved out of the way during early stages of the game. Once you get Flares, it will be a lot easier as well.
During this playthrough, assuming it's your second one, try to give Sleepy Cat Plush in your kitchen to every character you find. Not only you will receive some special new items but it's also needed for one of the endings.
During this step, try to keep “You”s mental health as high as possible. You can follow this walkthrough for the White Ending, along with Pacifist and Expert. It is my personal White Ending playthrough and you should get it if you follow it closely, it can also help you with getting almost all other trophies.
Step 3 - Load your last save and complete the game for Green Ending
Once you complete the game and get the White Ending, select Continue on main menu. If you followed the walkthrough provided here, you should get the Green Ending when you reach the room inside the Hospital.
Step 4 - Load your last save and complete the game for Blue Ending
Same as previous step, select Continue from the main menu. Upload your save to Cloud and do everything listed under Old Man and Demolished Man, before you head to the hospital. They should be enough for you to get the Blue Ending. But if your ending is Green, keep doing them for a little longer. If the ending is Red, download your save from Cloud and do them less this time.
Please check this walkthrough for details.
Step 5 - Start a New Game for Yellow Ending
For the Yellow Ending you must have finished the game at least once and tried to give the Sleepy Cat Plush you find in your apartment to every character you can find in the game on your second playthrough. If you did all that, you will get a new picture when you start your third new playthrough.
Please check this walkthrough for details.
Simply try to give the plush to Chie again during that new playthrough to finish the game with a Yellow Ending.
Step 6 - Clean up
You shouldn’t have any trophies left at this point, but if you do start a new game and earn them. It shouldn’t take more than 2 or 3 hours to complete the game when you know your way around.
