At the start of Chapter 4, you'll be controlling Mike as he pursues the creature that kidnapped Jessica. If you want to save her and keep her alive, you have to select all the risky routes and shortcuts then press the correct QTE buttons until you reach the abandoned mining facility. It's okay to have a mistake but you have to really be careful when pressing the QTE buttons since they're quite fast and they appear in inconvenient parts of the screen.
Butterfly Effect: To the Rescue |
Risk Shortcut: Mike will cross the river by hopping on top of broken pipes (3 QTE buttons) |
Follow Path: Mike will take the longer route. |
Go Around: Mike will take the longer route. |
Jump Down: Mike will slide down the steep slope (1 QTE button) then follow the obstacle-laden trail (4 QTE buttons) |
Jump: Mike will jump across the chasm (2 QTE buttons) |
Shimmy: Mike will take his time carefully shimmying along the edge. |
Follow Path: Mike will take the longer route. |
Risk Slide Down: Mike will slide down a very treacherous slope (2 QTE buttons) |
After the QTE galore, pick up the lamp and watch the following scene. If you still see Jessica getting dragged inside, you're still good. Continue forward until you reach Jessica. If she opens her eyes, she's alive and you'll be able to use her in the later chapters.
Butterfly Effect Update
In Chapter 9, if Jessica survives in Chapter 4, you'll see a brief cutscene where she survives the fall and gets up on her feet, badly wounded. In Chapter 10, she'll show up alone or with Matt (if he survives his Death flags). However, Jessica still needs to go through two more deathflags (alone or with Matt) by hiding from the Wendigo during the chapter in order for her to survive the game.
