This week you can find Xur in The Tower, inside the Hangar. For his weapon, Xur is offering Prometheus Lens. Hunters can pick up The Sixth Coyote chest armor; Titans can grab the Ashen Wake gauntlets; and Warlocks can buy the Apotheosis Veil helmet.

Spawn in using the Courtyard transmat zone in the Tower to find Xur this week. Head left and down the stairs to enter the Hangar section, then hang another left. Make your way to the north end of the area and look for a staircase that will take you onto a catwalk, where Xur is waiting.
