The Minecraft team has released “a handy video to illustrate exactly what to expect from the Minecraft Earth beta” on the Minecraft blog.
“We’ve even included actual moving images from said beta (with an impossibly upbeat, yet beautifully pedagogical voice-over by Stephen Scott of the Minecraft Earth Design Team, as a fun bonus!)”
The closed beta will launch for iOS in the next two weeks, with the Android version following soon thereafter. As with most closed betas, the number of participants will be limited in numbers and locations. This is to make sure our servers are able to keep up with all the exploration, creation and, hopefully, surviving that is going on around the world…
As is also common with beta versions, your progress will occasionally be reset as we test and develop various features of the game.
If you are selected to participate in the closed beta (congratulations!), you will receive an invitation email to the email address you have associated with the Microsoft Account or Xbox Live account you submitted in your registration. If you are selected (congrats again!), you will need to play at least once every 7 days. If you don’t, we’ll give your spot to someone else, as space in the beta is very limited.
You have to be 18 years or older to participate.
