ind all mementos in single player campaign in a single playthrough

MISSABLE

Mementos are the new extra collectable that are in the game, and they can only be picked up in single player. There are four in every level, and they can be found in the regular loot crates, though there will be a floating image of the memento above and a small pillar of purple light around the crate. The crate that they spawn in is random each playthrough, so there aren't any specific crates you need to search for. You will earn this trophy after you pick up the fourth memento in the final level. If you miss a memento in a level then you will not be able to earn the trophy in that playthrough. You can check what mementos you have collected in your current playthrough by going to Gallery on the main menu then selecting Mementos. This screen resets every playthrough so you can check to see if you have found all the mementos in the level you have played up to. If you are backing up your game save after each level you will be able to use that if you miss one in a level. Simply overwrite the save on your PS4 with the one you have backed up and it will allow you to play the last story level over again, without having to start a new playthrough.
