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 perk functions identically to the clairvoyance spell from Skyrim.

Bugs
If an area has navmesh issues or similar problems, V.A.N.S. will fail to show any path and just display an error message. This is fairly common in some of the more sprawling and/or vertical buildings (such as Corvega assembly plant).
