Firearms: Source.

Firearms: Source is a multiplayer first-person shooter modification for Half-Life 2, and a direct sequel to the GoldSrc mod for Half-Life, Firearms. Firearms: Source strives for a realistic depiction of real-life firearms in their operation and details.

The mod went into significant management issues later in its development, and was never completed. The final version of the mod that was publicly and officially released by the dev team is version 2.0.2. The mod was formerly featured on Steam, but can no longer be found. The mod also originally had its own official website (http://www.firearms-source.com/), which included additional info and images of weapons, but the website had also shut down.

The information present on this page come from version 2.0.2 of Firearm: Source, the last publicly released version of the mod.

The following weapons appear in the video game Wuzh/Sandbox:

Overview

Firearms: Source is a multiplayer first-person shooter. Players' choose a loadout upon spawn, the size of which is limited by the player's limited amount of credits. Weapons can be modified with attachments, which also cost credits. One of the player's skills increases reload speed by 25%, which often changes the weapons' reload animation to a new faster one (though this is not always the case; several weapons merely have their normal reload animations sped up).

In-game, ammunition is tracked by magazines for most weapons; partially reloading a weapon will make the player store the partially spent magazine for later use. Weapon chambering is tracked, so inserting a fresh magazine in a weapon already chambered will grant the player one additional round, in the weapons that allow this. Finally, bleeding wounds must be bandaged to stop health loss.

Changing fire modes in FA:S is not animated, and the viewmodel is stuck to a single fire mode position.

Handguns

Colt M1911A1

An original run Colt M1911A1 pistol with wooden grips is featured in Firearms: Source. It holds 7+1 rounds and is referred to as "M1911" ingame.

Glock 20

The 10mm Auto Glock 20 is featured in FA:S as one of the handguns, named "G20" ingame. It has a magazine size of 15 (+1) rounds.

IMI Desert Eagle Mark XIX

The Desert Eagle Mark XIX in .50 AE is featured in FA:S as a heavy-hitting pistol. It accurately uses 7-round magazines, plus one chambered. It is named "Desert Eagle" in-game.

OTs-33 Pernach

The OTs-33 Pernach appears as the sole machine pistol in FA:S, under the name "OTS-33". The OTs-33 fires the Russian 9x18mm round in 18-round magazines, plus one chambered. It can fire in either semi or full-auto.

Taurus Raging Bull

The Taurus Raging Bull is the only revolver in Firearms: Source. It has a 5-round cylinder and is chambered in .454 Casull. The revolver's ammunition is tracked by single rounds rather than magazines.

The Raging Bull has a set of extremely elaborate reload animations; there are five different reload animations, one for each capacity the revolver was at when the reload begins. All reload animations are done with single rounds, and show the player character ejecting the number of rounds that need to be replaced and inserting new ones. When the player does not have enough ammo to make a full reload, the reload with the number of rounds the player has in reserve will play (i.e. reload an empty cylinder with 4 rounds in reserve will play the 4-round reload animation). Reloads with the reload speed increase perk are simply normal reloads sped up.

Using the firing key when all 5 rounds were fired will still show the cylinder rotating fowards rather than doing nothing like in most games.

Holding the Raging Bull revolver. Oddly, unlike all the other handguns, the Raging Bull has a very slight idle animation, showing the player character gently bobbing his hands and fiddling his thumb.
Aiming.
Mid-recoil.
The player character opens up the cylinder at the start of the "standard" reload procedure, played when there's 1-3 rounds in the cylinder (2-4 rounds fired). Note how the number of fired rounds (indicated by struck primers) are accurate to the number of rounds that were actually fired, a very impressive detail.
In the standard reload procedure, the player character blocks the unfired rounds with his right thumb and ejects all the fired rounds, apparently by shaking them out.
The player character will then reload the cylinder with individual rounds.
Closing the cylinder upon finishing the "standard" reload procedure.
Reloading when there's 4 rounds in the cylinder (1 round fired) will show the player character flicking out the fired round...
...and insert a new round into the empty cylinder position.
A different cylinder closing motion is used at the end of the single round reload procedure.
Empty reload; the player character operates the ejector and ejects all the fired rounds...
...and inserts five new rounds, one by one, before closing the cylinder (with his thumb, like in the "standard" reload).

Shotguns

Benelli M3 Super 90

The Benelli M3 Super 90 is the only semi-automatic shotgun in FA:S. It is equipped with ghost ring sights, a pistol grip stock, a perforated barrel shroud, and a 6-shell shell holder. It holds 7+1 shells of 12 gauge 00 Buckshot, and is referred to as "M3S90" ingame.

Loading the magazine tube (without the Gunner level one perk); the user grabs up to two shells at once and loads them one after another into the magazine tube, repeating the process until full.
Loading a single shell to fill up the mag tube.
Very interestingly, the shell holder does play a part in gameplay, rather than being purely cosmetic like in 99% of the games; the represent the last 6 shells in the player's reserve ammo pool, and the player character will grab them and use them when the player is down to their last 6 shells. Here, the player character grabs a shell from the shell holder...
...and either chamberloads it...
... or inserts it into the magazine tube.
The M3 with an empty shell holder.
With the level one Gunner perk, the player character will grab up to four shells at a time to load the magazine tube rather than just two.

Remington 870

The Remington 870 was added in the 1.0e patch. The model was based off the Express Magnum variant with an extended magazine tube that holds 6 + 1 shells. The shotgun is pump-action only, firing a new round when the mouse button is depressed, and ejecting it and chambering another when it is released. It costs 32 credits and is named "R870".

A M1A1 Abrams tank is seen in the background, as most maps feature (unmovable) military vehicles to enhance the "war" feeling.

KS-23

Slated to be released in the Version 2.0 Update. It fires 23mm (which equate to 6.27 Gauge) Slugs out of a rifled barrel with 3+1 capacity. From gameplay footage seen, it functions as a "Shotgun Sniper".

KS-23

Submachine Guns

H&K MP5A4

The MP5A4 is a good submachine gun costing 24 credits, though it lacks the Picatinny-mounted ACOG seen in previous versions. The magazines hold 30 (+1) rounds of 9mm Parabellum and it offers either semi-auto, 3-round burst or full-auto firing modes. Referred to as "MP5-A4" ingame. In version 2.0, the MP5 is changed to the MP5A5 with a collapisble stock, fitted a Suppressor changes the weapon into the MP5SD6 and plans have been in the works for an MP5/40.

Ingram MAC-11

The Ingram MAC-11 is featured in FA:S as a cheap submachine gun (20 credits). It carries 32 rounds of .380 ACP and fires semi or full-auto. Named "MAC-11". It correctly fires from the the opened-bolt position. In the version 2.0 Update, the MAC-11 will be placed inside the "PDW" class of weapons due to it's small size and caliber.

Slated to be released in the Version 2.0 Update as apart of the new "PDW" category of weapons. Currently it's seems to use a 15 round magazine.

IMI Uzi

A full size IMI Uzi with the collapsible stock unfolded is slated to be released in the Version 2.0 Update.

Sterling L2A3

A sterling L2A3 is slated to be released in the Version 2.0 Update. It has been confirmed that both variants, the L2A3 and L34A1 "Suppressed" will featured.

Sterling L2A3 (MK IV) - 9x19mm

H&K MP5K

Slated to be released in the Version 2.0 update under the "PDW" class of weapons.

H&K MP5K

Izhmash PP-19 Bizon

Slated to be released in the Version 2.0 update. It has been confirmed the weapon is chambered in 9x18mm with a 64 Helical style magazine.

PP-19 - Early version in 9x18mm Makarov

Assault Rifles

AK-47

A powerful weapon firing the good, old 7.62x39mm. The AK-47 (named the same way ingame) costs 40 credits and is a good choice for medium to long-range combat, due to its stopping power. The magazines hold 30 (+1) rounds and semi or full-auto modes can be selected. Also, the rifle is fitted with a bayonet that can be used to stab enemy combatants, through the Weapon Melee command key. Weapon in game is a hybrid and has a AK smooth dustcover and a AKM stamped receiver.

AK-74

Slated to be released in the Version 2.0 Update.

AK-74 - 5,45x39mm

FAMAS F1/G2 Hybrid

Very appreciated by the FA expert players, the FAMAS provides a very high rate of fire for 42 credits. The main drawback is that the magazines hold only 25 (+1) rounds of 5.56x45mm ammunition and it has a high rate of fire, so it will empty magazines in no time. It's named "FA-MAS" ingame and offers semi-auto, 3-round burst or full-auto firing modes. Interestingly, the trigger guard is is that of a F1, but the handguard, magazine-well, and 30-round STANAG mag (though as stated above, it still holds 25 rounds) is from the more modern G2.

H&K G36C

The compact version of the G36 is not a bad option, costing 36 credits. It possesses medium stopping power, but has a useful AimPoint red-dot sight mounted to the Picatinny rail on the carrying handle. It's got options for semi-auto, an incorrect 2-round (even when the markings indicate 3) burst or full-auto firing modes. Referred to as "G36C".

Colt M16A2

Another classic weapon from FA that couldn't miss the show. The M16A2 costs 36 credits and offers good accuracy and decent power, in either semi-auto or 3-round burst modes. Magazines are standard NATO 30 (+1) rounds, and the weapon is named "M16-A2" in the menus.

Colt M4A1

Besides the 3-round burst being replaced by a full-auto firing mode, the M4A1 shares many properties with the M16A2, including the 30 (+1)-round mags, and costs the same (36 credits). There's nothing especially good or bad to say about it. It's named "M4-A1", and its default handguard was replaced by a KAC RAS railed handguard, that allowed the player to install a vertical grip to assist the aiming and firing.

SAKO Rk 95

This Finnish version of the AK-47 assault rifle is very similar in behaviour to the aforementioned, as it fires the same ammo, and even looks like it. But the cost is a bit higher (42 credits versus 40). Anyway, it's a good choice that can fire 30 (+1) deadly rounds of 7.62x39mm in semi or full-auto. The name ingame is "Sako 95" and, as with the M4A1, a railed handguard with 3 sets of Picatinny rails (below and to the sides) was installed to allow the use of a vertical grip.

SIG SG 551

While not having any long-range sight, this Swiss rifle is capable of hitting enemies at a good distance. It uses magazines of 30 (+1) rounds and lets you shoot in semi or full-auto. It costs 36 credits (same league as the M4A1 and M16A2) and is named "SG550".

SIG SG552

The Carbine variant of the SG 550 is set to appear in the Version 2.0 Update under the "Carbine" classification.

SIG SG 552 "Commando" - 5,56x45mm

Battle Rifles

H&K G3A3

40 credits does this steel and plastic piece of art cost. The G3A3's 20 (+1) rounds of 7.62x51mm ammunition pack quite a heavy punch. Named just "G3A3". There seems to be some kind of glitch with the 3D ingame model, as the parts that compose it move independently if looked at carefully.

SA M14

No game made by firearms enthusiasts could leave this weapon out. The M14 has the same powerful punch and mag capacity (20 + 1 rounds) of the G3A3, just the full-auto mode is not only a bit slower, but more uncontrollable. Be sure to stick with the semi-auto mode and make every bullet count. It appears to feature a Crye Precision Multicam woodland camo finish on the stock and no optical sight like in the GoldSrc version. It costs 36 credits and is named "M14".

Simonov SKS

Slated to be released for the Version 2.0 Update. Footage shows the weapon pre-fitted with a Bayonet just like the AK-47.

Simonov SKS - 7,62x39mm

Sniper Rifles

Remington M24 SWS

The Remington M24 Sniper Weapon System (SWS) is the U.S. Army version of the Model 700. It is an accurate, bolt-action, long-range sniper rifle. It is depicted in FA:S with woodland camo and a folding bipod, to make the gun more stable, that can be used if you prone or move near some places (like barrels, sandbags or... corpses). The cost is a high 54 credits and is referred to as "M24". The official website lists it as a M24A2, but this is erroneous, as no detachable external 10-round magazine is seen. Instead, the rifle uses an internal 5-round magazine.

KAC SR-25

The SR-25 is a multi-purpose sniper rifle that is able to fire semi-auto, It looks similar to a M16 (in fact, many parts are interchangeable between both), but fires the completely different 7.62x51mm NATO cartridge. It costs 48 credits, has a 10 (+1)-round magazine and is named just "SR25". The tan paint remembers that of the M110 SASS. It comes with a folding bipod (as with the other two sniper rifles), and an useful suppressor that reduces the firing report a bit.

It should be noted that the safety is engaged each time the player reloads the weapon, but once the weapon is reloaded, the safety is disengaged

M21

Slated to be released in the Version 2.0 Update. In early beta footage it shows with a 10 round magazine despite a 20 round magazine being shown (though it has been confirmed that this was done for balance reasons) and is seen using an olive drab finish, similar to that of an M14 DMR.

M21 - 7,62x51mm NATO

Dragunov SVD

Slated to be released in the Version 2.0 Update.

Dragunov SVD - 7,62x54mmR

Barrett M82A1

This 70-credit beast is the most expensive weapon in FA:S's arsenal, no doubt why. The "light fifty" can deliver an instant and gruesome death to anyone being so unfortunate as to be shot by this. The 10 (+1)-round magazine can maim equal number of foes, provided that the player is able to handle the enormous kickback of this long-range rifle. It fires semi-auto and is called "M82A1" ingame. It's the only weapon whose sight offers two different levels of zoom, and it's got a folding bipod, too.

Machine guns

FN M249-E2 SAW

The heat shield tells us this is the improved, E2 version of the SAW. The 200-round detachable box and the bipod makes this 50-credit machine gun perfect for covering fire. Of course, continuous fire while standing or running will get you nowhere. Called "M249 SAW" ingame, fires full-auto only. The Picatinny rail on the feeding-tray cover is never used.

FN M249-E2 Squad Automatic Weapon (SAW) - 5.56x45mm NATO

SD M60E3

"The Hog" is a bulky, heavy 7.62x51mm NATO machine gun with a lot of kickback unless fired on a deployed bipod. It feeds with 100-round ammo boxes and fires full-auto only. Called "M60-E3", costs 56 credits. As with the SAW, the Picatinny rail on the feeding-tray cover is never used.

Vollmer HK51-B

The Vollmer HK51-B. According to the official website, this weapon is "a standard HK51, but with a converted upper receiver that can accept belts of 7.62x51mm NATO. Such power compacted into the size of what essentially amounts to an MP5 frame results in terrible kick and poor accuracy". Little else is there to say. Ever tried to tame a horse in the middle of a firefight? Oh, an HK51 is a cut down and modified G3, NOT made officially by H&K. The weapon is referred to as the "MC51B Vollmer" ingame and costs 44 credits. Contrary to the other machine guns, a semi-auto firing mode is available. It loads from HK21 machinegun boxes running German DM1 Continuous Belts, though only has a capacity of 50 rounds as opposed to the HK21's 100. The HK51-B is also designed to use the M60's M13 disintegrating link belts instead. Nonetheless, the animation for reloading the gun is well done, as shown below.

RPK

Slated to be released in the Version 2.0 Update. It's been confirmed that the one currently in-game is the 7,62x39mm version fitted with a 40 round magazine and folding Bipod.

RPK

Launchers

M79 Grenade Launcher

Once again, another classic. The M79 single-shot, break-top, grenade launcher grants you average power when dealing with groups of opponents. The 40mm High Explosive grenades need to travel a minimum distance before arming themselves, to avoid misusage. It costs 45 credits and is named "M79" ingame.

Explosives

M67 Grenade

There is no much to say about FA:S's M67 hand grenade. You can get a couple of these for just 6 credits, but due to a recent patch its destructive power is not as high as it should be in real life, because throwing one and stepping onto it as it explodes will only take away less than the 70% of your life. Referred to as "M67 Frag Grenade" ingame.

M18A1 Claymore

The M18A1 Claymore, a remotely-detonated, directional, anti-personnel explosive device that can be used for setting some good ambushes. It costs 13 credits as is named plainly "Claymore" ingame. There are a couple of ways to control how it goes off. The first one is just to wait near the spot and hit the clicker when an enemy comes in front of it. The second one is the trip mode, in which the Claymore will be detonated when someone walks over it. By crouching or going prone, you can pass through the mine with out detonation.

M18 Smoke Grenade

The M18 Smoke Grenade is a good way of covering your advance, and an excellent countermeasure against snipers, you can get two M18 Smoke Grenades for 6 credits. They produce a thick, green smoke screen for some seconds. Use them wisely.

M84 Stun Grenade

Where there is a smoke grenade, there is a "Flashbang". It even costs the same (6 credits). Throwing one will produce a blinding flash and a deafening sound that will render enemies defenceless for some seconds, enough to finish them. Just be careful not to look towards it as it goes off.

M224 Mortar

The M224 Mortar does not appear in the loadout screen, as it is issued (unassembled) to the player when he or she earns the "Level 2 Artillery" skill. Then, the player will be able to assemble it anyplace, and fire to designated targets (see "Artillery Marker"). The player can carry up to 5 mortar shells.
