Night Vision Goggles are a helmet covering item introduced during the Night Vision update in May of 2020. They have received multiple tweaks since to adjust to game light mechanic changes.
From a defensive use perspective, they can most closely be compared to the Boonie Hat, with slightly lower marks in melee and cold protection. The purpose of the night vision goggles lies in the name; they allow for low-light visibility where you’d otherwise need a flashlight or torch. The major challenge is that their use is highly dependent on individual settings, with players using higher gamma and other assorted brightness buffs complaining of overwhelming screen blur and blinding green appearance.
Night vision goggles are found in a number of mid to high-tier crates throughout the world of RUST, along with being dropped by many varieties of scientists. Players may purchase them directly from Bandit Camp Black Market for the shockingly not-so-low price of 250 Scrap, or craft them after researching via the research table or making their way down the Tier 2 Work Bench. They boast a relatively high crafting cost for items of similar defensive stats and function.
