Death Road of Despair

Despair Death Road is a platformer minigame that can be played in Chapter 1 of Danganronpa V3: Killing Harmony. The player is not intended to complete this minigame due to its high difficulty level, however, if they do complete it, they will unlock a bonus scene featuring an alternate ending in which the students escape.

Gameplay
The minigame starts out with Kaede Akamatsu leading the other 15 students towards an exit while dodging obstacles such as gaps and bombs. If Kaede is harmed by any obstacle, she is knocked off the screen and unplayable, then replaced by another random character. This process will continue until the full minigame is completed, or all of the students are "dead". It is considered extremely difficult to complete.

Ending
(It doesn't matter who "lives" and completes the minigame, it will always be Kaede who talks to Monokuma in the Ending.)
 * Below is brief translated summary of the ending by @taichinchin on Tumblr.
