Guardians can initiate an Escalation Protocol by interacting with a node that causes a tower to rise up out of the ground. The tower draws Hive near to the location. Guardians must eliminate all Hive that appear before they escape.
There are seven waves, each successive wave more difficult than the last. The seventh wave has a boss that must be defeated using unique mechanics. Each boss rotates weekly and drops loot unique to that boss.
Any Guardians in the area may participate in an active event, but only Guardians who have completed the Warmind campaign will be able to initiate an event themselves.
- In order to open the chest that the final boss drops, the player must have a decrypted cache key.
