Minecraft has been available on tons of different devices in the past. Now, Microsoft is finally bringing all those platforms together with the “Better Together” update, which is rolling out today for Xbox One, mobile devices, and Windows 10 PCs. The Nintendo Switch is still set to get the Better Together update, too, although that’s been delayed until later in the winter.

The update essentially takes the different versions of Minecraft that have been available on PC, Xbox, iOS, and Android, and consolidates them into one master version, with the same features, functionality, and content no matter where you play. That means that the console versions of Minecraft on Xbox One (and eventually, the Nintendo Switch) will now run the same version of Minecraft as PCs, mobile, and VR, built on what Microsoft calls the Bedrock Engine.
