We've released an extremely early build of BUILT with basic multiplayer which features span (timber/planks) and block (stone) placement.
You can play either Single Player or join our Multiplayer server which is located in South East Asia. We'll be adding more servers located in other regions in the future and dedicated servers will be available during the BETA.
The server doesn't save at the moment so if it get's rebooted all your constructions will be deleted.
Please feel free to comment here or email us at firstname.lastname@example.org if you have any bugs to report.
