Bungie debuted 12 minutes of gameplay from their anticipated Destiny
at E3 and they've now brought online the demo walkthrough in HD. You can check it out below.
In the game, everything changed with the arrival of the Traveler. It sparked a Golden Age when our civilization spanned the solar system, but it didn't last. Something hit us, knocked us down. The survivors built a city beneath the Traveler, and have begun to explore our old worlds, only to find them filled with deadly foes.
You are a Guardian of the last safe city on Earth, able to wield incredible power. Defend the City. Defeat our enemies. Reclaim all that we have lost. Be brave.
