Xbox controller support has been added to the game! You will now have the option to play the game by using a Xbox controller. There is currently one default button layout for testing purposes, but please do not hesitate to give us your feedback and info regarding the layouts you wish to see in the game; (the same addition will be introduced to Space Engineers in the near future and it is related to the development of the Xbox One version). Another additions are the modding guide and mod example for multi-block objects, peasant sounds, tree roots and more destruction performance optimizations. There has also been various improvements to the stability of the multiplayer mode based on the community feedback.
