Along with the Launch Trailer, Bungie has released the patch notes for Update 2.0, which brings pretty hefty changes to the way the weapons, exotics, Milestones, rewards, and player abilities work. Some exciting stuff available now, and some more will be accessible when Forsaken drops on Tuesday.
This update isn't the last change that you'll see from Bungie, though, and they've made a post detailing what's to come in the months after Forsaken's launch. Whether or not you buy into the $30 Annual Pass, it looks like there will be quite a few things to look forward to over the next year!
