Bungie describes Earth's moon in Destiny as "broken" and this image shows large cracks. That's what you get for storing nuclear waste on the dark side, guys. (Just kidding.)

The Citadel is described as a place where bad guys live; all bad guys need an evil lair. In the foreground, two Guardians face off against some Vex.

This image shows an example of each of the player classes so far revealed: the hooded Hunter, most likely a stealth-based class, the magic-wielding Warlock, and the gun-toting Titan.

It is not known if other player classes exist or will exist, or whether factions fall strictly along class lines or include members of all possible classes.

This image was the first piece of concept art revealed after the first leak in November 2012.

It shows the enemy known as the Fallen. A spider tank trudges through the snow in the distance, and one of the figures appears to be shadowed by what might be a companion drone of some sort.

"Fallen" could also be seen as a reference to Bungie's RTS series, Myth. Myth's first title was Myth: The Fallen Lords.

The Exclusion Zone is on Mars, one of many locations in the solar system you can travel to in Destiny. The green banners apparently represent the large, rhinoceros-like Cabal enemies.

A spaceship, possibly human in origin, hangs below the rings of Saturn.

Destiny apparently takes place within humanity's home solar system. The lack of more distant locations would seem to indicate that humanity lacks faster than light travel in this universe at this point in time, definitely dividing it from the Halo universe, where humanity achieved FTL travel earlier.

This image of human ruins apparently is located somewhere in the former Soviet Union. A small sign over the door reads in Cyrillic, "Inna Tour", presumably a travel agency.

A Hunter, in the left foreground, attempts to avoid the notice of a patrol of Fallen (foreground) and Cabal (background).
