Set in the distant future, Destiny casts players as Guardians of the last city on Earth, who traverse the ruins of our solar system from the red dunes of Mars to the jungles of Venus. Players must battle enemies and reclaim what was lost during the collapse of mankind. Destiny's saga unfolds through grand tales and sweeping adventures by immersing gamers in a world with cooperative, competitive, public, and social activities.

Everything changed with the arrival of the Traveler. Long ago, it breathed new life into our system. Rain washed over Mars. Fresh air cleansed the skies over Venus. Soon after, humanity raced into the black, and colonized these newly remade worlds. It was a time of miracles – a great Golden Age.

It did not last. The Traveler had an ancient enemy. A powerful darkness that found us here on Earth, and nearly destroyed us. No one knows exactly what happened in those final moments, but we know this: we survived, and we owe our lives to the Traveler.

In our darkest days, Humans, Exos, and Awoken found the Traveler where it made its last stand, low above Earth, silent and immobile. We built the City – our last – within its protective veil, fighting countless wars to keep its peace. From that dark age, Guardians were born.

Now, a new era has begun, and the only hope for our future lies in unlocking the greatest mysteries of our past. You are a Guardian of the last safe city on Earth, able to wield some of the Traveler's incredible power. You are taking this mantle just as a new day dawns. Titans, Hunters, and Warlocks have finally returned to our long-lost worlds, only to find out we are not alone.

Defend the last safe City on Earth. Defeat our enemies. Explore the ancient ruins of our solar system. Discover all that we have lost.

Become legend.

Scheduled for release on Dec. 9, 2014, The Dark Below marks the first expansion to the Destiny universe and features all-new weapons and gear to earn through new story, cooperative and multiplayer activities.

"Destiny was created as a living universe, which has allowed us to improve the experience post launch in real-time," says Harold Ryan, President of Bungie. "It also gives us insight into the things players are looking for in new content. We've seen from feedback that people want new activities, gear and weapons, and of course the immensely popular Raid. The community helps shape our development decisions and that's really important to us."

 Destiny Expansion I: The Dark Below will feature the following:

• New weapons, armor, and gear to earn, including Legendary and Exotic items
• Light Level cap raised to 32 and five additional Bounty slots added
• New story quests and missions - after years hiding amongst the Hive shadows, a new character, Eris, has come forth bearing an ominous warning: The Hive seek to summon a god, Crota, to destroy the Earth. Find Eris in the Tower to take on special quests that include three new missions where you will increase your Light and earn new rewards
• New cooperative Strike, The Will of Crota, pits you and your Fireteam against Omnigul as she works to expand the Hive army at the command of her master, Crota
• Three new competitive multiplayer arenas
  • Pantheon - set deep within the Black Garden in an ancient Vex temple that features Vex-designed landscapes and tight corridors
  • Skyshock - an old interplanetary defense array that offers both vehicle and infantry engagements
  • The Cauldron - an abandoned Hive ritual site that offers close-quarter combat
• New six-player Raid, Crota's End, set deep within the depths of the Hellmouth
• PlayStation platforms will also get access to an exclusive cooperative Strike, The Undying Mind, and more (timed exclusive until at least Fall 2015)
