OverviewEditNight vision goggles are used to sneak through areas or seeing traps when the player cannot risk using their flashlight. When the goggles are switched on, the player is much harder to detect than when they have the flashlight turned on. If the player uses the flashlight and the night vision together, they can extend the range of the NVG and see better. This drains the battery faster by around 40 percent, making the battery only last about 2 minutes from the original amount of about 3 minutes 20 seconds, but this makes it easier to see in very dark areas and is of great use when stealth isn't necessary. Like Artyom's watch, the 2033 version of NVG features a stealth meter at the top; red means the player is in well-lit area that easily detectable, yellow means the enemy will find you if they get close, green means you are hidden, but you will still can be seen if you are in close proximity with the enemy, finally "no light" means you are completely hidden, only noise can give your location away.
One should keep in mind the drawbacks to using the goggles however. When the goggles are on, well-lit areas become difficult to manage through. The goggles obscure Artyom's peripheral vision. If the player is swarmed in an area with nosalises or lurkers, it is a good idea to take them off and use the flashlight instead. Taking them off will allow the player to see any mutants or NPCs trying to flank them.
In Metro: Last Light, the NVG return but with some slight differences; they reduce the wearers maximum visual range to some extent as any target the user may see will appear hazy and unclear. They can no longer be used in combination with a flashlight but appears to be equipped with an infrared spotlight (the infrared equivalent of a flashlight) which has the same effect as using the NVG and the flashlight together, but without the extra battery drain or revealing the user's location. The NVG in Last Light no longer obscure the player's vision, has a larger field of view, and the clearer vision means you can snipe with NVG equipped. Also, the wearing animation is removed, you will automatically equip the NVG right after pressing the N (default) key.
- Armory level (bundled with the stealth suit).
- Behind Artyom after falling off of the rail cart in Front Line in a small red box protected by Communist soldiers, along with a few MGRs and a moral point.
- On the communist side of Front Line. The destroyed tunnel in which the injured Communist soldiers are sleeping has a side door. A gas mask is not required to explore the foggy side hall (as long as the player moves very quickly) but it is recommended. Near the end you will find the goggles and a small collection of ammo.
- After being rescued by Ulman and Pavel, directly behind Artyom through the door.
- Can be looted from the Nazis in Black Station, or found near the supplies.
- At Sparta, near the rifles and the ammo.
- At the start of Dungeon in a small room directly in front of Artyom on a small crate with lots of ammo and health packs.
Metro: Last Light
- Found on the second floor of the abandoned ranger outpost near start of the level Nightfall, be very careful for the traps inside that post.
- If you miss the first pair of night vision goggles on the Nightfall level, you can find a pair of them on the level Contagion. The goggles can be found along with a Tihar on a table in the area where two Red soldiers are executing people.
- The world model of the NVG and the one Artyom uses do not match.
- These are most likely third or fourth generation night vision goggles, because the vision is quite clear, they are almost silent, and there isn't a loud whine created by them when turned on or in use. (Night vision goggles present in game show in shape some resemblance to real-world Russian military PNV-57e - 1st Generation night vision goggles.)
- However, you still can hear the NVG activation sound from NPCs, if the enemy nearby put it on.
- The night vision goggles in Metro games are passive NVGs, which amplifies the existing light; player can notice the effect of the NVG was slightly worsen when they go to extremely dark areas. However, the Last Light version has the optional IR projector to amplify th effect, which make it closer to the active NVG.
- Miller, on several cases, will randomly acquire and lose his night vision throughout the game's story.
- Ulman in 2033 is easily identified because he is the only Ranger to wear his night vision during all missions.
- Scopes are very hard to use with night vision, as the dirt on the scopes creates a bright green glare while looking through it. Use the red dot laser sight on the scope to help you.
- In Metro: Last Light, the combination of a scope and NVG is much easier to use than in Metro 2033.
- It is possible to loot night vision goggles from dead enemies from the mission Frontline and onward.
- The faint light projected from the Night Vision can be seen on the NVG users in the Polis entrance, but in most other cases, no light will be seen on the NVG.
- In Last Light and Redux version, if combined the NVG with an IR scope, the effect of the IR scope is no longer apparent - although it is still possible to aim.
- The infrared spotlight can prove to be a problem, since it lights walls up so that they're almost completely white, obscuring your vision. This is especially noticeable in the Redux games, where the brightness of the game has been increased substantially. Both Redux games have few areas dark enough that the NVG are essential.
- A glitch in the 2033 Redux causes Artyom to put on the NVG every time a cutscene happens where you lose control of Artyom, such as being knocked out at Defense or right before entering the trolley on Trolley Combat. A fix would be to not pick up the NVG, but this makes Frontline and subsequent levels significantly harder. This glitch does not occur in the Last Light Redux.
