Not Available Everywhere
The Gears of War 4 beta is going to be available in a number of countries but there are two places that won't get access to the game ahead of its release date.
Microsoft and The Coalition have ruled out a Gears of War 4 beta for China and Japan. That's obviously unfortunate for those that live there and we don't expect that to change before, or after, the start of the beta. It should hold.
It should be available just about everywhere else though.
