Metro: Last Light (also known unofficially as "Metro 2034") is the sequel of the acclaimed horror-shooter, Metro 2033. The story follows Artyom, the main protagonist in the previous game, trying to make contact with the last Dark One alive on Earth.
The sequel, Metro Exodus, was announced in E3 2017 and currently scheduled for release in 2019.
The following weapons can be seen in the video game Metro: Last Light:
The "Revolver" returns from the previous game, and can be modified with various attachments. Like in Metro 2033, the model is not based on any particular real firearm, but it does bear a resemblance to Russian Groza-series civilian less-than-lethal revolvers (with a S&W-style cylinder latch).
"Lolife" pistol
"Lolife" is a makeshift pistol chambered in .44 Magnum. First found in the hands of a Russian neo-Nazi officer in the "Pavel" mission. This pistol can be modified with a vast variety of attachments including a full-auto firing mode (which will significantly reduce accuracy due to the kicking recoil). It is an amalgamation of Mauser M712 Schnellfeuer pistol and Kedr PP-91 submachinegun. It also has strong visual similarities to the Bergmann No.5 Model 1897 pistol.
Assault Rifles
AK-74M
The AK-74M appears as the "Kalash" and can be modified with various attachments, including a sound suppressor, laser sight, 45-round magazine, and various optics. It differs from the Metro 2033 version by having a darker paintjob, a heatshield on the fore end, and more realistic rear ironsights.
AKS-74U
The AKS-74U is a Ranger Mode exclusive carbine, with stats very similar to the base Kalash of the game. It can accept the same attachments as its big brother.
"Kalash 2012"
The "Kalash 2012" or "AK-2012" (a fictional bullpup assault rifle based on the FN P90) return from the previous game. It has similar stats as in the first game; high damage, good accuracy and a 40-round capacity.
"Bastard"
The home-made submachine gun based on the Sten returns from the previous game. The new model is more detailed and has a longer barrel.
Shotguns
"Duplet"
The home-made double barreled SxS shotgun also returns from Metro 2033. This time it can be modified, among everything else, by adding two more barrels. The gun then can also be fired two or all four barrels at once, the latter capable of bringing down almost any enemy at point-blank range.
Saiga-12
The Saiga-12 is the ultimate close-quarters weapon with its high damage and automatic fire mode. While real Saiga shotguns are semi-automatic, it is not completely impossible to convert them to be able to fire fully automatic. The Saiga can accept a sound suppressor, drum mag, and three types of sights.
Machine Guns
RPK-74
The RPK-74 appears as the "RPK" in the Limited Edition of the game. It can be used with a 45-round or 100-round drum magazine, although the latter one is incorrect for a real life RPK-74.
The VSK-94 appears in the later parts of the game. It is correctly shown to be fully automatic, but it incorrectly uses 5.45x39mm rounds. Has an extended barrel when not equipped with a suppressor.
VSSK
The VSSK appears in Faction Pack and Developer Pack DLCs. It is incorrectly depicted to be semi-automatic; while the real VSSK is straight-pull bolt-action.
"The Valve"
This is a straight-pull, bolt action rifle that appears to be made out of parts from a Mosin-Nagant (bolt and front sight) and a Schmidt-Rubin K-31 (bolt handle with the distinctive wooden knob and the bolt carrier that makes it a straight-pull action). This frankenrifle is fed by a detachable magazine mounted on the left side.
