Escalation Protocol
Things to Do After Beating Destiny 2: Warmind
Escalation Protocol is a brand new horde mode public event introduced in Destiny 2 with the Warmind expansion. You can join in on the event before completing the campaign if you see other Guardians attempting it on Mars, but we advise against doing so. Even at Power level 340, completing the first level in Escalation Protocol can be very challenging, so you should definitely go finish the story and level up a little before trying this.
Destiny 2: Warmind’s public event can only be triggered on Mars, and you have to look for squarish metal plates on the ground that emit a red glow, not unlike the ones you saw from the Valkyrie javelin nodes in the story itself. Interact with it, and you’ll start the event. You’ll have to kill all enemies and complete all objectives within the time limit in order to proceed. If you succeed, you’ll get some nice rewards to boost your Power level.
