I found all the endings except No. 5. Can you tell me what it is?
So, the no. 4 ending is Alone. You fend for yourself on your own.
To get this ending, you need to be evil (I think) and have a low relationship with Lizzie and the guy. First, kill Ivan. There will be a fight between Lizzie and Ryan/Malcolm a few scenes after that. By this time, the third option will no longer be blank. Choose that option. KILL THEM BOTH.
