Halo 5 beta

So I completed the halo 2 anniversary campaign and was very happy. Naturally I wanted to try out the halo 5 multiplayer beta. After looking around the menus I found it under extras and was very disappointed to see that it was grey and unable to be selected. I did download it to my Xbox one digitally, but I made sure it was completely downloaded. If anyone could help I would really appreciate it.

Its not available until 29th Dec

The beta isn’t out yet.

Its canceled they broke the servers.
