Xbox Live
If you want to play online, the easiest way to accomplish this is to use Xbox Live. Everyone needs an account but you don't need to pay for Xbox Live Gold to play online.
In this mode, five crafters can play in the same world at one time.
Players should start by logging in to Xbox Live from the options menu. This will take you to the Xbox website where you can jam in your credentials and pick your gamer tag.
Then, the host player needs to open the options menu and make sure "Multiplayer Game" and "Broadcast to Xbox Live" are both on.
Then the host enters the map.
The other players can then press "Play" on the main menu, move over to the friends tab, and should see the host's game under "Joinable Friends". Just tap it to get started.
the host can also invite players over Xbox Live from the pause menu.
