In a statement on their website, Bungie stated that:
“Our work is not done. There is more we can learn. To make this happen, we need more Guardians to play. This is, above all else, a test.
Today, at 4:00 PM PDT, we’re opening the Destiny Beta to anyone who wants to create a character and walk in their boots. There are, of course, some requirements. You’ll need to have a compatible console equipped with PlayStation Plus or Xbox Live Gold. You’ll need to be brave.
Help us deliver the game you deserve. Before we shut this party down, we’ll welcome everyone who wants a preview of this brave new world. If you have yet to play Destiny, look for offers to download the Beta directly from your console later on this afternoon.”
The Destiny beta has gone off without a hitch so far, this is in spite of increased interest in the game. This could be seen as the reason why Bungie have decided to let anyone play the game and to help them improve it before release on 9th September.
