The first Up Challenge was equivalent to a cooperative survival theme.
It required them to coordinate to navigate the treacherous obstacles through sheer will. If either one of them lost their will or no longer had the motivation to continue, then they would have fallen there.
The second challenge was a parkour challenge in which the two were no longer chained up and were free.
However, the twist was that to advance forward, both players had to complete the parkour challenge at the same time.
This required them to have the will to pursue their goal of achieving success together.
Despite the setbacks and how one of them finished a little bit faster, they had to endure and restart the process from scratch.
The third challenge was a completely different environment. They were forced into an environment where monsters overrun civilization.
