Tips on how to save, or lose, all eight characters in Until Dawn
Jessica
Jessica (played by Meaghan Martin) starts off as an unsympathetic and over-sexualized character. When you play Episode 4, you play Mike. A creature drags away Jessica, and you have to chase after her. If you fail every QTE button push, Mike won’t reach her in time. She’ll fall from above and hit the floor dead. If you reach her in time, she lies on the floor of an elevator. Then the elevator gives way and falls down into the mine. Mike believes she’s dead at that point, but we discover in the final, Episode 10, that she’s still alive. At that point, she tries to escape a Wendigo, creatures that are the real killers, in the mine.
