Been so long since I last tried to obtain the "Scene Complete" trophy in Psycho-Pass: Mandatory Happiness because both English and Japanese forums have been very inactive so, they haven't been of much help. There are some detailed guides out there that show how to achieve all the endings (including bad ones) but again, I still missed a few despite following them very closely.

For me personally, I was missing files 12, 59, 63 and 68. Fortunately, a year after I decided to re-visit the game the scenes I was after finally appeared in search results. Turns out I missed two bad endings and two enroute scenes.

Still, I've yet to find a place that listed all the scenes so I've decided to put a list together myself. I played the Japanese version of the game so some choices won't be exactly the same as the English translation.

And I shouldn't have to warn you about spoilers.

Scene Complete Trophy

A guide on PSN Profiles should help you through any routes you've missed or need to re-visit and you can just hit R1 to speed through the text you've already read. Turning up the speed in settings will help it skip a bit faster but be sure not to leave the event scene until it's over or it won't be unlocked.

The list is incomplete because the scene viewer isn't very helpful - it doesn't show you which route, chapter it's from when you review them or, what possible choices are available during the scene. I've put together what I could from scouring the internet and if like me you followed a guide, got all the endings but still missing certain scenes, hopefully this will help.

Voice Complete, Picture Complete Trophy

As for the the other voice and picture complete trophies, you'll need a total of 605,000 points to fully unlock voices and 312,000 points for pictures.

It might seem a lot but if you manage to complete up to level 9-1 of the mini puzzle game you'll save more than 600K worth of points (assuming you haven't spent any to unlock anything already!) thanks to the bonus points it gives when completing each level for the first time. Much better than free play.

The game's actually not too hard too. I got stuck at 6-2 then struggled a bit after 8-4 but just keep at it since the tiles seem to be randomly spawned so sometimes you might get lucky. By level 9-1, it's pretty much freeplay but the target square is only half the points you need.

Once you have around 600K points (depending if you already spent any points or not and I did already...) the trick is to unlock everything at once but don't press the back button. Instead, once you see the trophy get unlocked for picture complete, exit the game so that it doesn't save the number of points you used and then you'll have your points back to unlock the next section.
