Get in right now
Destiny's beta went down for maintenance yesterday. It was meant to come back on July 23, but it's back up right now, giving you something to do tonight. Me, I'm making ramen. Like, actual ramen, not an instant, 10 cent salt lick.
Bungie gave this statement. "We know you’ve been waiting, so we busted our asses to finish our chores up early. You can download and play the Beta right now. This is a great moment for the entire Bungie Community to share in this adventure, and we couldn't be more excited. Get in there. Break it. Tell us what you think. Share your experiences online."
Also remember there's that, "permanent reward on reserve that will commemorate the experience" for people who play on July 26, 2PM PDT. The beta closes the following day.
