Who Will Live and Who Will Die?

This trap was put in Until Dawn. I know it is not a Jigsaw trap, but its still pretty cool, so I decided to put it in. Its a fun game where your decisions and actions will affect your story. If you guys wanna see this trap for yourself, then definitely get the game.

The Victims of this trap are Ashley, Josh, and Chris. There is not much reason for them to be put in this trap. Well maybe because they pulled a prank on Josh's sister causing her to run into the forest never to be seen again along with her twin sister when she chased after her.

The Trap

Chris enters the room. He sees his friends Josh and Ashley tied up to the wall. He is unable to reach them due to the gate in front of him. On the other side of this gate is a circular saw, with rails that go straight and then to each person. On Chris's side, there is a lever. On each side of the lever is the picture of Ashley and Josh.

How this trap works

Chris is forced to choose to save either the girl he likes, or his best friend. He must pull the lever to the picture of who he chooses not to save, causing the saw to use the rail to travel to the victim, sawing him/her in half.
