"So, our game is called Destiny." That's how Bungie's blog post confirming a February 17, 2013 reveal for its first non-Halo effort in more than a decade opens. Try to act surprised. The blog post doesn't actually confirm that date, but the newly launched Destiny Twitter feed does.
Bungie doesn't have much to say in the here and now. We know from a leaked infodump in November 2012 that the story picks up seven hundred years in the future. An alien ship sits motionless above the planet "like a second Moon" while alien monsters invade from outside our solar system.
It seems that players will assume the role of Knights, who are tasked with protecting Earth and its Last City. Follow along with the recently launched ARG and stay tuned for new details very, very soon.
