Creator Markus Alexej Persson has confirmed that the collaborative multiplayer game will leave alpha status on December 20.
The change will see a price increase to €14.95 (£13 / $20) and will remove the licence that agrees to free updates to all future versions of the game.
"With beta comes a larger focus on polish and content, and we'll start early on with adding proper modding support with a stable API, and we'd love all input we can get on this from the modders out there," said Persson.
"We'll also add some kind of non-intrusive narrative to the game to help drive the game experience early on, and to provide some kind of late game goal. There will be a bigger focus on testing and stability as well, with more time between updates."
Earlier this year it was revealed that Persson was making $350k (£220k) a day from sales of the game.
