VANS

V.A.N.S. (Vault-Tec Assisted Navigational System) is a perk in Fallout 4.

Effects
V.A.N.S. shows where the Sole Survivor needs to go to arrive at their quest marker in V.A.T.S., usually alongside roads and paths. If the player character is offroad, the line will first draw towards a path. The green smoke-like line is short, but walking in the direction of the line will show more of the line.

Behind the scenes
This is functionally identical to the clairvoyance spell from Skyrim.
