Editors Notes

1. For better, For worse and Cold Blooded not working
If one or the other achievements or both are not working this is because you have reloaded the game trying to get the other ending. For some reason the game doesn't like that so you have to basically play on 8 different saves for both achievements. You can skip the credits since the entity shows after you trigger all good or bad endings before the credits and will get the trickster to show up as well.

2. Do not attempt to modify/replace BSW.dll file it's outdated and will cause your game to just be black screen and if you revert replacing the file game does not work correctly. If this happens verify the files and it will work again.

3. You do not need to play the good and bad endings 8 times for each killer like trickster states it's kinda of a waste of time but you do you I guess.
