Weapons Exchange

Weapons Exchange is a Fallen public event. Guardians must defeat a Walker (in Destiny 2, an Arsenal Walker) in the middle of a Fallen weapons deal; in the first Destiny it was "Destroy the Fallen Walker" (Cosmodrome, Moon, Venus, Plaguelands). In Destiny 2 it appears in places such as the European Dead Zone and Titan. On Heroic, shooting the Walker's legs drops Arc Charges; depositing them in generators opens weapon caches and triggers a harder version with two Walkers.
