History of Radar

Radar is the Crucible HUD element showing nearby enemies in a general direction, with no walls, paths or exact positions. Per a Destiny community guide its range is 30 meters; moving, shooting, jumping or throwing grenades keeps enemies on it, while crouching or cloaked enemies only flicker. It is hidden when aiming down sights, except with perks such as Knucklehead Radar. These details come from a search summary of Destiny guides and may be out of date.
