Thermal Goggles

Thermal Goggles are a piece of equipment featured in Call of Duty: Ghosts. They are used in the level "End of the Line". The goggles will highlight enemies in red, while most of the surrounding area will be in purple/magenta.

A similar version of the Thermal Goggles appear in multiplayer with the Predator Field Order. They function almost identically to the campaign version, albeit that most of the area will be blue. Enemies will still be highlighted in red, however.
