Destiny 2 was teased heavily last week, mainly via a reveal trailer (added below) and an image dropped on Twitter by Bungie. Since then fans have been trying to gather as much intel as possible from both sources, but perhaps the most concrete piece of info has come via the below image that shows off the Expansion Pass.

Fans may recognise the two symbols shown therein. One represents the Warlock, Osiris, who inspired the Trials of Osiris multiplayer event. Might we be heading to his stomping ground on Mercury for some sort of adventure? It definitely looks like something along those lines.
The other symbol represents the Warminds, who players will no doubt remember being the focus of more than one outing in the original game. It was certainly hinted that the Warmind Rasputin might have a bigger role to play in the future. With that in mind, it's certainly not unreasonable to assume that this will be the focus of the other expansion.
We also learned from this info sheet that the expansions will land in winter 2017 and spring 2018 respectively, bringing with them "brand new story missions, cooperative activities, competitive multiplayer, and a wealth of new weapons, armor, and gear."
Destiny 2 is heading to PC, PlayStation 4, and Xbox One on September 8, and you can read more about it by hitting this link. But first, here's last week's reveal trailer.
