Yeah, they talked about multiple different new overworld things. Like dungeons to find, treasure maps leading to valuable chests, side quests from characters you find in the world.
Honestly I wished they had showed this instead of talked about it.
That is what is leading me to be luke warm on it.
From what they showed it looked like a prettier, more refined Destiny. Which is fine if they really back up the talk woth stuff to do that's interesting.
I am interested in the beta, but I feel like Bungie missed an opportunity to show more. I don't care about the story missions, after TTK I am happy knowing with what a Luke smith team can deliver.
It really was Patrols, and areas to discover that consisted of the bigger let down in D1. They should have show a real gameplay trailer just showing a player dropped in patrol and running off to do something for a minute.
