You came across an abandoned building in the middle of nowhere. You think it is worth a try to enter this building and have some investigation.
The Undermine Challenge Map is a parkour + maze map where you try to complete 1 level (6 mini-levels) of parkour trial. It might be easy or difficult for you depending on your skills.
/gamemode 2 is the most preferable gamemode. Even if you cannot pass through one jump, please do not give up by changing your gamemode. All jumps are possible (3 testers have completed this challenge so do not worry about the possibility).
Good luck on completing this challenge.
