Rundom is a multiplayer parkour map with a randomized parkour and a random gamemode ! Depending on the gamemode, the game will be very different: a Wither trying to shoot you, a strong wind, a rain of anvils... and many others !
You can modify a lot of settings from the lobby, like the difficulty and the length of the parkour, the time limit... If there are a lot of players, you can activate the teams, it will be more fun !
A custom resource pack should be automatically installed. But if it didn't work, you can download it here.
