During a live program for destiny 2: Age of Destiny, Bongi announced that it would introduce global levels. These are the difficulties of the customized location, with various difficulties and increased rewards.

Robbie Stevens, Assistant Game Director of Destiny, announced the increase and commented that when guardians play through the struggle of the main story, they will unlock more global levels and therefore more difficulties.
“Global levels allow you to face the highest challenge,” Stevens explained, the more difficult it is, the more you will return. Think about it as a global diabetic globally. High people are more difficult, but the most beneficial in terms of gear.
The first place to get this treatment will be the Kepler. This new place will be introduced along the edge of destiny and, unlike its real -world counterpart, will be present within the solar system, on its edge. Bongi did not note whether the difficulty of the location would spread to its existing places, or it would be eliminated only in new breadth.
It is not too late to wait for us to know, as Bongi has announced the name of the next three extension in the Destiny 2 Roadmap along with the date of release of destiny.
