This guide is based on the text within the game as to how each image is unlocked, happy to take suggestions of notes to add for those that aren’t explicit on how to get them!

All of the “uncharacteristic” achievements are during the After Story but it’s not clear to me yet if they trigger via certain choices, or if it’s random who will act out of order during each run – I suspect the former so if you do try each choice branch you should get them all.
