The following weapons are used in the video game Half-Life 2 and its episodic sequels:



Heckler & Koch USP Match

The Heckler & Koch USP Match in 9x19mm is the standard issue sidearm of the Combine's 'Civil Protection' police force. It is first seen wielded by a guard in the train station and is soon after used against the player as they flee across the rooftops in the chapter "Point Insertion". Later, one can be taken from a slain CP and then used throughout the game. Its stopping power is lax, but its decent accuracy, rate of fire, and high capacity make it suitable for a variety of applications, such as attacking weak but difficult to hit enemies like headcrabs and manhacks and setting explosive barrels on fire from a distance. Oddly enough, while it can be found in many supply caches and beside civilian corpses, Resistance members are never actually seen using it.

Despite it using standard 15-round magazines (with finger-rest floorplates like the picture below), it holds 18 rounds like the extended magazines that are meant to be used in conjunction with H&K's "Jet-funnel" extended mag-wells.

One detail worth noting: the weapon doesn't eject empty casings when fired, while the (otherwise identical) pistol in the pre-release beta demonstrations did, this is a bug. A fixed model that does eject casings can be found on FPSBanana. It must be also noted that the slide always locks back when a reload is started, even if there were unfired rounds in the chamber and magazine. The weapon's slide also is released automatically when a fresh magazine is inserted, instead of using the slide release.

Colt Python

The .357 Magnum Colt Python is first acquired by the player in a Civil Protection outpost in the chapter "Water Hazard". It's powerful, accurate, and can kill many lower end enemies in one shot and most of the higher end ones with a well placed shot to the head. Its accuracy makes it effective at long range if its user utilizes the suit zoom. Simply zoom in on an enemies head, quickly zoom out, and fire. The side of the V_model barrel reads "COLT PYTHON ELITE".

Ammunition for this weapon is rare when you first get it. Later on it becomes a little more common, but resupply remains relatively infrequent, which means it has to be used sparingly.

There happen to be several major problems with the .357's model that would prevent it from even being usable in real life: For one thing, the ammunition that Freeman loads into his gun has spent primers. Secondly, the ejector rod (which is connected directly to the cylinder itself) and the crane that connects the cylinder to the gun stay stuck in the gun's frame during its reload animation, which means that there's nothing connecting the cylinder to the gun in the first place, it's just miraculously floating there in mid air. Finally, there's no speed-loader or moon clip used during its reload animation, so the shells are just magically held together when Freeman loads them into the cylinder. He also has a habit of spinning the cylinder after swinging it back into battery.

In addition the w_model says "Colt Anaconda" on the side of the barrel, even though the weapon is supposed to be (and modeled after) a .357 Python.

Submachine Guns

Heckler & Koch MP7 Prototype

The original Heckler & Koch MP7 Prototype is the main weapon for most Resistance members and Combine Soldiers, and is also issued to Civil Protection teams in volatile situations. The game's model of the gun is different to the real thing in several ways:

  • Although the 1st person model is fairly true to the real 2nd MP7 prototype, the 3rd person model has significant differences in its proportion and shape.
  • It is fitted with a very small holographic sight that cannot be used by the player and has no iron sights at all.
  • The correct caliber (4.6x30mm) is written on the ammunition boxes, but cartridge casings that are ejected when the weapon is fired say ".45 Colt" on the bottom.
  • The weapon's magazine capacity is 45 rounds, but no extended magazine is visible protruding from the grip. The real world MP7 comes with 20, 30 and 40 round magazines. The 40 round magazine protrudes from the grip and is curved.
  • Its secondary fire capability fires up to 3 grenades semi-automatically, but there is no mounted grenade launcher on the weapon. Instead, the grenades seem to be fired out of a second barrel (which is smaller in diameter than the grenades it fires). The weapon itself is also too small to plausibly contain a launcher, let alone storage for three grenades and a semi-automatic feed system for them. These abilities are uncharacteristic of the weapon's design, but are characteristic of the OICW assault rifle (which was originally the Combine's standard issue automatic weapon, the role the MP7 now fills). Given the correlation it can be surmised that when the developers opted to use the MP7 as the generic automatic weapon, they grafted the OICW's grenade launcher capability onto it to make it more useful.

Given the opportunity, Resistance members using this weapon usually discard it in favor of a more powerful AR2 Pulse Rifle or SPAS-12 shotgun.

Franchi SPAS-12

The Franchi SPAS-12 without a stock is used by the Combine Overwatch and some Resistance members. It is first given to the player by the crazed Ravenholm preacher Father Grigori in the chapter "We Don't Go To Ravenholm...". It is very useful in close quarters combat, particularly against Headcrab Zombies and Antlions. One soldier in each Combine squad is equipped with the SPAS-12. It is also used by some major characters on occasion:

  • At the end of the "Entanglement" chapter, Dr. Isaac Kleiner is briefly seen wielding one.
  • In Episode One, Alyx Vance acquires one from a Combine supply cache and wields it throughout the following chapter.

In Half-Life 2, like many other games, the player can only use the SPAS-12 in pump-action mode, while the real one can be switched between semi-auto and pump-action based on the power of loads it's using. NPCs appear to use the weapon in semi-auto mode, however. It only holds six shells like the short barreled variant, although the in-game model shows the full-size version which should hold eight instead.

Just like in the original Half-Life, it has the unrealistic ability to fire two shells at the same time (yet only ejects one shell). The magazine tube is mistaken for a second barrel, and both "barrels" can be fired at once for the secondary fire mode; the game even gives an on-screen hint calling this ability "fire both barrels". Additionally, Gordon still reloads the SPAS-12 incorrectly in the sequel by cramming new shells into its heatshield instead of the actual loading port.

Winchester Model 1886

The Winchester 1886 is used by Father Grigori in the chapter "We don't go to Ravenholm...". Grigori has nicknamed his rifle 'Annabelle'. The weapon is identified in earlier versions of the game by the loading gate. In the game, it functions as a double-barrel rifle with one shot per barrel and .357 Magnum chambering, despite its real life counterpart holding 9 rounds in the tubular magazine and not being available in .357 Magnum. It contains high-damage values when dealing with enemies and can be given to the player despite never being intended to if the game story is followed.

Like the "Alyxgun", Annabelle can be spawned through the developer's console using the code "give weapon_annabelle", or by using some glitches. Because it wasn't intended to be usable, the view model is identical to the SPAS-12's and the animations are riddled with glitches. However, a fixed V_Model can be found here.

MK3A2 Offensive Hand Grenade

While "M82 FRAG" is written on them in-game, the hand grenades in Half-Life 2 are closely based on the MK3A2 concussion grenade, but emit a red LED light and a beeping sound when armed as they are made by the Combine Overwatch for its soldiers.

AT4 Rocket Launcher

The rocket launcher in Half-Life 2 is based on the Saab Bofors Dynamics AT4, albeit backwards (the launcher's barrel is actually the AT4's rear in real life) and with a Stinger-like grip assembly. Having replaced the GAM14B (A futuristic version of the Armbrust ATW) from HL1, it is quite frequently used by the Resistance members to take down Striders and Gunships. It is still laser-guided. The weapon's rockets are extremely sophisticated; they are able to be corrected mid flight instantaneously simply by aiming the launcher at a different location, are extremely maneuverable, and never run out of fuel.

The SLAM was cut from Half-Life 2, but was later re-used in Half-Life 2: Deathmatch where it has two modes of operation; can be used as a laser tripmine to set up ambushes or can be used as remotely detonated explosives, similar to the Satchel Charge of the original Half-Life. While the tripmine version in the game emits a visible red laser, the real SLAM uses a passive infrared sensor. The player can carry a total of 5 SLAMs.

Cut Weapons

These are weapons that were included in the leaked beta of Half-Life 2:


The AKM , known in the game as "AR1" was to be given to many of the Rebels. The in-game AKM holds 30 rounds and has 5 different firing modes, ranging from fastest to slowest, the faster modes being weaker, and the slower firing modes dealing more damage per shot.

Heckler & Koch XM29 OICW

The XM29 OICW was to be the standard weapon of the Combine forces. It was removed from the game following a brush-up on consistency with weapon standards and themes relevant to the game. The game OICW featured a functional scope with a green tint, and early alphas allowed for the grenade launcher to be fired. The gun was made redundant with the addition of an SMG that could launch grenades.

Heckler & Koch GR9

The Heckler & Koch GR9 known as the "HMG-1" was supposed to be a portable machine gun in the game and was to be carried by Overwatch soldiers. It features two firing modes: fully automatic, and 3-round-burst, and the scope was not a usable feature. The rounds fired also dealt incredible damage.

LAR Grizzly Big Boar .50 BMG Rifle

Early versions of the game included a .50 caliber LAR Grizzly Big Boar sniper rifle with a modified grip that encircled the shooters trigger hand and a special red scope. The rifle was incredibly powerful and had two zoom levels, a non-working muzzleflash effect which took up the entire screen, and a long reload time as it was single shot only. It is used by the Combine Snipers in early versions and was replaced in the final released game with a crossbow that fired super-heated pieces of rebar.

Heckler & Koch MP5K

The Heckler & Koch MP5K, aka "SMG-1", is a removed weapon in Half-Life 2. It can be seen and is the primary submachine gun in the Half-Life 2 leaked alpha. The MP5K featured two firing modes: fully automatic and burst fire.

Orion Flare Gun

The 25mm Orion flare gun is another cut weapon that was supposed to be used by Combine soldiers and guards at Nova Prospekt. It is an older pre-1995 model of the Orion 25mm signal launcher made from metal and standard plastic blue grips. It can fire flares normally or has an alternate fire that allows it to launch flares underwater (although they do not travel very far). Unlike the real Orion signal gun, the in-game Orion is Double Action.
