The achievements in this game are based on the endings you get. If you manage to get all the endings, you’ll also get all the achievements. The path lines help you see where each ending is located. A few endings in Chapter 3 require specific choices made in earlier chapters, but the rest are quite straightforward. Getting all the paths also means you’ve seen all the scenes and obtained all the keys. Don’t forget to do all the QTEs with both success and failure, as both outcomes are required.

2) To go to the bottom path - In Chapter 2, choose Reject Shen Man (you need to help her drink in previous selection, if not it will go to BE) and reach the ending of Chapter 2.

3) Bella ending - In Chapter 1, choose to meet Bella at the bar.
