Introduction - Please Read this First
As I'm sure everyone is now aware, Heavy Rain is not your typical game. The story is driven and changed by the choices that you make, resulting in a myriad of different scenes and endings, which makes collecting trophies a complicated affair. Having said that, this is not a game that should be played solely for trophies. As a result, if you have not played the game through to the end yet, I'll ask that you only read Step 1 of this road map. Once you have played through the game and received whatever trophies and ending you have earned, come back here and continue through the road map and guide for the rest of the trophies. There are a couple things to keep in mind before reading either the road map or the guide:
1. There are no missable trophies. Every chapter can be replayed in order to unlock the different endings and individual trophies. That being said, don't worry about going back and replaying chapters until you have beaten the game once.
2. The trophies aren't glitched. Of course there are exceptions, but for nearly everyone who plays the game, the trophies work fine. Some of the requirements for the trophies are complicated, the controls can be finicky at times, and the trophies don't unlock until the end of the chapter. Before you come in here crying glitch, make absolutely sure you've tried everything, and you've checked to see if other people have had the same problem. The Kamikaze trophy is a perfect example of a trophy that, while tricky, is not glitched.
Step 1 - If you haven't played the game yet, only read this step
This step is simple; all you need to do is go play the game. Experience the story however it unfolds, and make whichever choices that seem right to you. If something goes wrong, keep playing, rather than replaying the chapter. No matter how the game ends, you will unlock certain trophies, so just enjoy the game. If you want to focus on something, you can try to keep all the main characters alive, but if you don't, it can easily be fixed after the fact. Once you've played through to the credits, you can come back here for Step 2.
Step 2 - Four Heroes/The Perfect Crime
The first thing to do is to get the Four Heroes trophy if you haven't already. Provided your first playthrough wasn't a complete catastrophe, this won't take long to get. By following the guide, you'll need to make sure everyone makes it to the final scene alive. Once that's done, you can focus on getting the Perfect Crime trophy, and along the way, the Nerd trophy and the Trial Master trophy, if you haven't already done it. To do this, you'll need to replay the Crime Scene chapter to find all the clues with ARI (make sure you have auto save on here), and then play through the game again, starting at the Hassan's Shop chapter. Follow all of the steps in the Perfect Crime walkthrough, and for each of the Trials, be sure to complete them, if you haven't already, for the Trial Master trophy. When you reach the Mad Jack and Fish Tank scenes, follow the guide to find all the evidence needed, and in Solving the Puzzle, solve the mystery with the evidence in ARI. Once you complete the game after following the steps for The Perfect Crime, those three trophies should unlock.
Step 3 - Missing Individual Trophies
The next thing to take care of are any of the individual scene trophies you may have missed. In a lot of cases, you'll need to just replay a scene and make the opposite choice you did the first time around, or finding something in the scene you missed. In other cases, you'll need to complete a sequence perfectly, like Kamikaze, Ludwig Von, and Invincible Scott. There are two trophies you might want to get out of the way first: Happy Birthday and Kamikaze. In both cases, the scenes are fairly long, and they've given people some trouble. Check the trophy guide for both, but please keep in mind that Happy Birthday will not unlock until the beginning of Scott's chapter.
Step 4 - The Rest of the Endings
At this point, all you should be missing is the All Endings trophy. With the exception of a couple endings, you will only have to replay the game from the Killer's Place chapter onwards to see the rest of the endings. Check the guide for the criteria for each ending.
