Ahead of next week's release of Destiny 2, the Destiny companion app has received a huge overhaul. It's available to download now, and from a first look at the app, it has become a lot more social. In the first Destiny, the companion app was mainly a way to check your gear and your game stats. Destiny 2's app presents a lot more information about Destiny, Bungie, and the community right up front.

For example, upon launching the app, you're now greeted with the Explore section, which is essentially a feed of all the news and posts published to Bungie's website. Explore is laid out a lot like a social news site--there are tabs for "trending" posts, news, creations, community posts, and game updates. It's already a good way to see all of the official news about the game, but the coolest parts of the Explore section are the ones that are tied to the community.
