A Rising Chorus in Destiny 2 continues in its second week, focusing on analyzing specimens on Nessus. Guardians must work with Failsafe in Episode Echoes Act 1 to determine what is happening to the Vex and the planet. After the events of The Final Shape, a new development has begun on Nessus, unlike anything seen before. Week 1 began with Failsafe contacting the Vanguard about strange behavior in the Vex. She, with help from the Guardian, determined that both the enemy and the planet are changing. Players were tasked with locating radiolaria samples on Nessus.
