Night-vision goggles

Night-vision goggles are a piece of cut headwear in Fallout 3, Fallout: New Vegas and Fallout Tactics and were to appear in Van Buren and Fallout: Brotherhood of Steel 2.

Fallout 3
Meshes and an inventory icon for night-vision goggles appear in the Fallout 3 resource files but are unused.

Fallout: New Vegas
The graphical assets from Fallout 3 for the night vision goggles do not remain in the Fallout: New Vegas art files (except the inventory icon). The model folder contains .egm files (used in Gamebryo engine games to modify equipment placement, i.e., on male and female-shaped heads) which were not present in Fallout 3 data.

Fallout Tactics
Night-vision goggles were set to appear in Fallout Tactics, but were cut.

Van Buren
General Colridge, Captain Davidson, Captain Pierce and Major Briggs all carry night-vision goggles.

Fallout: Brotherhood of Steel 2
Wearing night-vision goggles creates a green filter over the screen and enemies will glow allowing the user to see them after sundown or in poorly lit areas.
