Well, they finally got it working. As expected, they tacked on more time (four extra days) to the Beta to make up for the errors.
I’ve downloaded the client but haven’t had a chance to play yet. I’ll probably toss up a few comments over the weekend after I’ve had my butt sorely kicked by the diehards. In the meantime, check out the Beta-celebratory video from the folks at Red vs. Blue.
