Sony moved towards the end of their E3 presentation by showing the first gameplay footage of Bungie's Destiny. This came alongside an announcement that Destiny would arrive in 2014.
An on-stage demonstration of the game showcased one player meeting up with another for some co-op action exploring a derelict factory in Old Russia. The two took down a boss, fawned over their loot, and then joined a larger player event (i.e. raid boss). Check out the first gameplay trailer.
