One of the new features coming to Destiny 2 is what Bungie is calling "Guided Games." This is where a solo player can group up with a higher-level players to help learn the ropes of end-game activities such as Nightfalls and Raids. The Guided Games feature officially rolls out on September 26, but it's been available for testers for a little over a week now in beta form, and Bungie has now talked about how many people tested it out and what it learned from the beta.

Senior designer Steve Dolan said in the latest Bungie weekly blog post that more than 100,000 people have used the Guided Games feature to get through the Nightfall Strike, with a 90 percent completion rate. For Nightfalls, communication is important for the success of a team. Dolan pointed out in the blog that while players are not forced to join group chat, it is recommended. But even if you don't have a mic or don't want to use one, listening in on the battle chatter can help your team get through a mission easier.
