Bungie revealed during today's livestream that Destiny 2 Year 2 will bring major changes, including a new raid called Dreaming City, a new Gambit mode that will combine PvE with PvP in a potentially very interesting way, new super abilities, randomized weapon rolls and mods in the style of Destiny 1, and a brand-new weapon class: bows. 

The Forsaken expansion, which will kick off Year 2 on September 4, will take place on The Reef, as previously rumored, and will feature a "Western revenge vibe" built around a major breakout from the Prison of Elders. This leaves a flood of bad guys overrunning the Tangled Shore, a new location on The Reef, headed up by "Barons"—bosses with different powers and abilities who players will have to take out in "Baron hunts."
