Don't Starve has found a lot of fans and became a big success for Klei Entertainment. The studio doesn't want to get stuck and moves forward. The MMO, co-op and similar games are widely accepted so why not to create something similar? When the game is already done?
Therefore you will be allowed to enjoy Don't Starve Together. And together is not just a name but means the core element of the game. Play together, die together. Simply written :-).
Watch the trailers and get ready for December 15 when the game will get available on Steam Early Access.
