Bungie said the story is created to dive deep into Destiny lore, focusing on Osiris and, more specifically, the Vex and their true intentions for the universe. There are also going to be those that will like that we'll be spending more time exploring the Leviathan instead of leaving it behind. Mercury itself will get a new destination in the Destiny 2 Director, the Fields of Glass.
The first of three Destiny 2 - Expansion I: Curse of Osiris livestreams will be broadcast at 11:00 am PST/ 2:00 pm EST/7 pm GMT. Before the story of Destiny, Osiris was once part of the Vanguard but he was exiled and remained on Mercury.
As with every other Destiny expansion, Curse of Osiris will give players new weapons, new armor, new places to go, and new enemies to kill.
Curse of Osiris was revealed at the tail-end of October alongside a new trailer. If you weren't around to see it, don't fret! It features new encounters and locations, and an all new boss at the end.
There is a new full raid on the Leviathan called "Eater of Worlds", but it's shorter than the original Leviathan raid.
What we could see on stream certainly looked interesting, and hopefully builds onto the Destiny 2 we now have to provide fun and interesting new challenges for players. Previously set at 305, the new Light level has been confirmed to raise to 330. The Raid Lair will be shorter than the original raid which may be useful for those who can not spend consecutive hours playing. Bungie also plans to bump up the Power Level requirements and rewards for the vanilla Leviathan raid, so players will still have reason to play it as well. However, the developers did mention that the Raid Lair is challenging, and a Prestige mode will be added on eventually. Heroic Strikes are coming back, and they'll offer more powerful loot for overcoming increased challenge.
