Experimental Gameplay

Experimental Gameplay (also known in-game as Experiments) is a game option exclusive to. When enabled, it allows players to test some unfinished or work-in-progress features that would eventually be released in future updates.

Toggling
Experimental Gameplay is found in the world options when creating or editing a world. When turning the option on in an existing world, a copy of the world will be created automatically. Turning the option on disables achievements after the world is created. Once the experimental world is created, it cannot be turned off again. Worlds with the experimental on will have an "Experimental" tag right next to the game mode name in the world menu.

Warnings
The point of Experimental Gameplay is for the player to look at some not-quite-finished features, which could crash, break, or stop working at any point in future updates. When the player attempts to load the experimental world, it will show a warning message before loading it. Attempting to disable experimental gameplay toggle via external tools could also crash and break the world.

It is recommended to create back up copies of the world when playing on experimental, or not enabling experimental toggle on to avoid breaking the world and having issues in future updates.
