Upheaval is a minor OneNation collab. The gameplay has been designed by ZenthicYoshi while the decorations are being done by SheikahGD and Trainiac. The level is designed to be like Cataclysm, but with slightly different gameplay. It uses the song At The Speed Of Light by Dimrain47.
On January 28, 2017, Upheaval was rebooted due to its relatively poor gameplay and severe inactivity. It will contain the 3 creators still in it, and maybe a few more people.
However, due to no one having an interest in it, Upheaval may be canceled.
