The night vision goggles is an equipment that can be used in the Syphon Filter series.
Capable of illuminating all nearby bodies, these nightvision goggles are use-only (not available in inventory). They are automatically donned when an area becomes too dark for an agent to make out objects.
Syphon Filter 2
The NVG is automatically switched on in dark environments, such as in the mission Gregorav.
Syphon Filter Omega Strain
This device can be found and used in Carthage 1, Carthage 2, Belarus 1, Yemen 1, Minsk, Lorelei, Tokyo and Ukraine. Enemies will equip it; the player only has a flashlight, so they have to search different areas and corpses to acquire it.
Syphon Filter Dark Mirror and Logan's Shadow
Unlike SFOS, the device is already found in player's inventories for every mission.
The NVG is great for illuminating sheer darkness, but looking at lights will blind its user.
The torchlight, on the other hand, will draw enemies to its wielder, although users do not have to worry about being incapacitated when they face bright objects.
