The Tihar (Russian: Тихарь), spelled Tikhar in Metro: Last Light and Metro Exodus, is a semi-automatic multi-stroke air gun that was created from scrap by the Metro dwellers at some point after the Great War of 2013.

Overview

Despite some shortcomings in comparison with conventional firearms in use, the air guns seem popular in the Metro. With pre-war laws, limitations, or regulations no longer applicable and with parts readily available, weapons such as the Tihar are a popular alternative to actual firearms.

The Tihar is extremely quiet and is capable of silently bringing down enemies from surprisingly long ranges. It carries fifteen 15 mm ball bearings in a tubular spring-fed magazine. The ammunition is propelled by a cylinder of compressed air placed inside the stock of the gun, which attains its pressure by a handpump at the end of the handguard. A pressure gauge mounted on the right side of the weapon shows how much relative stopping power and distance the next shot will have, with each shot draining a small amount of air from the reservoir.

It's possible to overpressurise the cylinder for extra stopping power or range, but the extra air will leak out eventually and the gun will revert to normal power levels. In Metro: Last Light, it can be modified to stop the air from leaking. The sound of the gas leak will not alert the enemy of Artyom's position.

In Metro 2033, the first Tihar is available as early as the "Lost Tunnel" level. It can be looted from a corpse in the dead end side tunnel near the exit from Riga station.

In Metro: Last Light, it appears that the Tihar is being phased out by the new version "Tihar-M" ("M" stands for модернизирован, transliteral "modernizirovan", identical to English "modernization" and commonly used in Russian weapon designations), as indicated by the production markings. All versions of the gun that Artyom comes across were produced by "Blacksmith Prokhorov" in 2030, which is stamped on the side. Tihar-M's performance remains largely unchanged in comparison with Tihar from Metro 2033. Its biggest improvement is the wider range of customization options.

Tactics and Use

The Tihar has a wide variety of uses and is quite effective from the moment it's picked up. While its pneumatic firing mechanism requires constant pumping and causes the Tihar's damage to often become steadily weaker in pitched firefights, it is also effective in combat situations and has little trouble picking off enemies

In emergency situations, the Tihar can fire rapidly - while this depletes its comparatively small magazine, and causes it to depressurise quickly, this feature can, if fully-pumped, cause considerable damage, making it quite effective when used indoors or at close-range.

The Tihar's damage is directly tied to its pressure; if fully-pressurised, the Tihar's shots cause heavy damage and can bring down a watcher in a single body shot.

This works both ways, however; if its pressure is too low, the Tihar is functionally ineffective, firing pellets that lack penetration power and have no capability to deal damage to a target. Because of this, it should be fully pumped at all times or at least, keep the pressure meter above 6.

A sign that the Tihar is pressurised is a sound of gas leaking and the pressure meter arrow is moving up and down quickly. The Tihar at this point also has greater power and accuracy; it can usually kill with a single shot to the chest, making it easier to dispatch enemies wearing helmets or gas masks. The amount of the pressure seems not to affect the dropping effect of the ball bearings, however, even the gauge is below 6, the Tihar is still moderately accurate.

As with the Helsing and the Volt Driver, when first found or exchanged, the Tihar will need to be charged before it can be used.

The Tihar, like the Helsing, hisses softly when over-pressurised. This hissing can be heard by enemies and can reveal your location if Atryom gets too close. Bear this in mind and keep a distance to maximize the Tihar's capabilities for stealth.

One issue with the Tihar is that the glass in its scope is somewhat cloudy and may cause problems with target definition, so those looking for a sniper-esque weapon may want to reconsider using the Tihar. A weapon equipped with the PK-AV scope may be better. The scope is not recommended for low-performance systems, as using it is known to cause lag.

The Tihar faces some competition for its role as a suppressed weapon from the VSV, revolver with silencer, scope and stock, the Kalash 2012 with a silencer and scope, and perhaps, the Helsing. The Tihar sets itself apart from these guns in a few ways; it is, by default quiet, does not require valuable 5.45mm rounds, has considerably better single-shot punch than the Kalash 2012 or revolver when fully charged, and is generally easier to use than the Helsing. Its ammunition is the cheapest on offer so it does not cost a lot to run one.

The Helsing is the Tihar's true rival, weapon-slot wise; both guns are pneumatic. The Helsing fires arrows while the Tihar fires small pellets. Also, there is chance Helsing's arrows can be recovered. The Tihar makes up for this though as its ammunition is the cheapest to exchange at kiosks. The ball bearings are also more common to find than arrows. In Metro: Last Light, the Tihar is similar in function, yet the gun and its ammo are not as common. Ammo for it should be purchased whenever visiting ammo vendors if intending to keep it, as it's a good weapon in stealth-based levels, without the need to purchase a silencer.

The Tihar faces some competition with Volt Driver as well; both use the same kind of ammunition and when charged to full power, they are both lethal to most enemies. Both are capable of sniping as well, though the Tihar is more accurate by a small margin. The Volt Driver, however, is considered to be more versatile, accepts more attachments and is easier to use. The Tihar's biggest advantage over the Volt Driver is the weapon's low price tag and more common, and the fact that the Tihar is completely silent, unlike the Volt Driver.

Variants and Customization

Metro: Last Light

The Tikhar has two attachment slots and five available attachments in total. Attachments in the Misc slot can be equipped both at once, so the Tikhar can have up to three different attachments at the same time.

Metro Exodus

The Tikhar shares stock upgrades with the Valve and the Helsing. It is able to equip all three laser gadgets and the Reflex Sight, NV Scope, and x6 Scope. The Mechanism and Magazine upgrades are unique to this weapon. Instead of upgrading the barrel, one can make changes to its pneumatic system, either increasing its efficiency or making it to auto-refill. It is even possible to replace the pneumatic system with a railgun mechanism, which essentially turns the weapon into a Volt Driver and increases the damage enormously, making most enemies a one-shot kill. With this upgrade, the Tikhar is can be a rather effective weapon, boasting huge damage, fast rate of fire and cheap ammunition that can be crafted on the go. To balance it out, this upgrade is only available in the last level, "The Dead City. After finishing the game, however, and starting a new playthrough in New Game +, the Railgun upgrade can be equipped right from the start.

Trivia

• The word Tihar (Russian: Тихарь) means "silent one".
• In Metro 2033, it is spelled Tihar. In Metro: Last Light and Metro Exodus, however, it's spelled Tikhar. This is due to there being no literal translation of the Russian name -Тихарь, as the Cyrillic 'x' is not exactly the same as an English 'h'. Although it's common to use 'kh' as a different romanization, neither is incorrect.
• The Tihar has a pressure gauge that is easier to check than that of the Helsing.
• The unique scope is actually "open optics" - a line of three aperture glass sights, which also accommodate compensation for pressure dependent bullet drop.
• The three lenses of the scope appear to be backwards compared to reality, where a larger objective lens normally gathers light into a focus closer to a smaller eyepiece. The lenses could however have unusual non-convex shapes that change the focal point correctly.
• One way to gain a lot of military ammo is to sell the Volt Driver found when fighting the bandits, with Bourbon for a Tihar with a scope in Market Station.
• In the concept art of the Tihar, it appeared as it was originally to be equipped with a PK-AV sniper scope.
• Despite being fairly common, a Tihar is never used by NPCs during gameplay. The intro cutscene, however, shows a soldier armed with one at the VDNKh fortifications.
• If Artyom is left idle with the Tihar equipped, he will examine the weapon and fiddle with the front sight on the gun.
• Many would believe this gun is technically a silenced sniper rifle, frankly because of its range and none already existing in the game without DLC, but it is more of a carbine because of firing speed and lacking penetration power. Also, the ball bearings may bounce off and remove armor.
• Given the shape of the front grip and stock, the Tihar could have been built from a VSV.
• In reality, a Tihar's ammunition would neither be particularly accurate nor possess much penetrating power against body armour - certainly not to the point that they could be considered useful sniper ammunition capable of accurately and quietly penetrating military-grade helmets at a good distance, like they can when fired from a fully-pressurized Tihar in the games. Spherical projectiles have all but disappeared from use in modern-day guns (one major exception being the spherical pellets used in shotgun ammunition, where low individual accuracy and poor armour penetration are not considered major issues), due to the fact that they cannot be effectively spin-stabilized by a gun's rifling and thus are not particularly accurate when fired. Using scavenged steel ball bearings as-is in a Tihar-like air gun would also restrict it to being a short-ranged weapon, both due to the aforementioned inaccuracy and the fact that the comparatively low density of steel, as opposed to the denser and more commonly-used lead-cored ammunition in conventional firearms, would mean that the steel ball bearings would possess low momentum and thus low effective range before losing too much velocity from air drag to be useful. These aforementioned factors, plus the subsonic firing velocity, would also make Tihar ammunition less-than-suited to penetrating body armour, as the steel balls would possess low sectional density (as opposed to a bullet- or arrow-shaped object) and thus be very hard-pressed to penetrate the metal helmets or other metallic body armour seen in the games.

Bugs

• The Tihar's scope can be hard to use at medium or lower resolutions, as the cross-hair lines are extremely thin, resulting in them "disappearing between the pixels"
• The Tihar's scope may cause delays when used, making it very difficult to aim.
• In Metro Last Light Redux, if the Tikhar is equipped with a Laser Sight attachment, the laser dot will be misaligned, pointing a little bit to right and down from the center of the screen.
