Thermal Vision

Thermal Vision is a gameplay mechanic in Fortnite: Battle Royale. It was introduced in Season 4. It is a mechanic that highlights players or certain objects in the environment to allow for longer distance and un-obscured viewing of them.

Functionality
Thermal Vision works by highlighting players or certain objects in the environment, by contrasting them greatly with the background. Thermal Vision will either highlight a player warm colors, such as orange and red on a dark blue backdrop, or it will highlight them white or grey, on a dark backdrop. This allows the objects to contrast and be seen easier.

Thermal Vision works through transparent objects, such as damaged or under construction structures. This allows players to be highlighted and identified easier through them. Thermal Vision also works through fog and smoke, so things like The Storm's obstructing purple mist, or the smoke from a Smoke Grenade will be ignored with Thermal Vision.

However, Thermal Vision can make it difficult to gauge distance, as the backdrop created by Thermal vision is bland and similar, meaning an object that is large and far away, may appear similar to one close and smaller. On top of this, Thermal Vision can make it difficult to identify Targets. For example, a player may attack an AI such as a IO Guard instead of an enemy player, as it is very difficult to distinguish between them when they are highlighted the same color.

Things that are highlighted with Thermal Vision include:


 * Opponents (Enemies, AIs etc.), and Friendly Players
 * Vehicles
