The "Death Switch" was the alternate sequences of death scenarios.
For example, after one person, which is an outdoorsman fell onto the trap and died, it rewinds back to this near death part. So an outdoorsman didn't lose its footing as he sees the trap so he moves away. Now an outdoorsman tries to step into the pitfall with spikes and got impaled, but it rewinds back to this near death part as an outdoorsman steps onto the same pitfall, but backs off. Now, an outdoorsman finally got assassinated by another outdoorsman, who mistakenly shoots his friend (an outdoorsman) that looks like a wild animal. Now, an outdoorsman was shot to death and never survived. That's ths sample story about the Death Switch story.
