From GameWatcher: “New Light is going to be a huge boon for everyone who’s even remotely interested in Destiny 2, and with two weeks to go, chances are that you’re wondering what content is free when the update launches.
The first information we had on free New Light content was that only the first year of releases would be available for players trying the game out, but the truth is that there’s going to be far more stuff available even if you don’t spend any money at all.”
