Colt Detective Special 

First appearing in 1927, the Colt Detective Special is a carbon steel framed double-action short-barreled revolver, a class of firearms known to gun enthusiasts as “snubnosed", “snubbies", or “belly guns". As the name “Detective Special" suggests, this class of gun was used as a concealed weapon by plainclothes police detectives. The Detective Special was the first premium grade swing-out revolver designed from the outset to be carried concealed and capable of chambering the .38 Special, a high powered cartridge in the 1920s. This weapon was produced through 1995, and the stats are representative of other small, concealed-carry revolvers. This weapon or something like it is very likely to be the sidearm of police and private detectives. 

Walther PPK 

Available in one form or another since 1929, this is a blowback operated, semi-automatic pocket pistol well suited for concealed carry. Functionally identical to any number of other holdout pistols, the Walther PPK has the unique distinction of being James Bond’s gun. 

Glock 17 

Just one in a long series of semi-automatic pistols designed and produced by Glock GmbH, located in Deutsch-Wagram, Austria. Glock controls the majority of the law enforcement market share in the United States. This is the weapon most police officers will be using, especially state troopers and local cops in urban and rural areas. 


A Taser is an electroshock weapon that uses electrical current to disrupt voluntary muscle control. Rather than mere pain compliance, the Taser allegedly causes total “neuromuscular incapacitation" using electro-muscular disruption technology. Tasers are nonlethal weapons used by police to subdue fleeing, belligerent, or potentially dangerous suspects, in the place of using more lethal weapons. A Taser inflicts nonlethal damage, uses pistol ranges, and does not work outside of short range. 


For civilian hobbyists, mini-crossbow pistols are perfect for target practice and small game hunting. Typically, mini-crossbows are constructed of impact-resistant ABS with an 80-lb. draw eight fiberglass blow; some use hardened steel parts instead. The crossbow includes adjustable sights for precision accuracy. Agents and operatives of the powers that be sometimes use mini-crossbows with injection bolts for assassination and capture missions (varying the chemical payload as needed) due to the fact that the weapon is totally silent, even more than a silenced pistol. The mini crossbow must be reloaded after every shot. 

Colt M1911a1 

The most iconic handgun ever made, used by everyone from Humphrey Bogart's Sam Spade to the American GI, the Colt .45 automatic pistol was developed in 1911 by John Browning and remained the primary sidearm of U.S. armed forces until its replacement in 1985 by the M9. The M1911 is a single-action, semi-automatic, magazine-fed, recoil-operated handgun chambered for the .45 ACP cartridge. It was widely used in World War I, World War II, the Korean War, and the Vietnam War. In total, the United States procured around 2.7 million M1911 and M1911A1 pistols during its service life. Incredibly, the practically antediluvian M1911a1 is still preferred and used by Special Forces units, for its reliability and incredible stopping power. If you’ve seen a handgun in a movie, there’s a 50% chance that it was a Colt M1911a1 or a clone thereof. Statistically, M1911 clones, like Springfield Armory replicas and the AMT Hardballer, are identical to the original weapon. 

Colt Python 

Developed in 1955, Colt Python is a double action revolver chambered for the powerful .357 Magnum cartridge built on Colt's large I-frame. Pythons have a reputation for accuracy, smooth trigger pull and a tight cylinder lock-up. Some consider them to be among the finest revolvers ever made. This intimidating weapon is still used by some badass highway patrols throughout the country. 

Tranquilizer Pistol 

These compressed air dart-projectors are usually used for animal control. This one is built on the frame of the Mk. 22 Mod 0 “Hush Puppy", a slide-locked Navy Seal modification of the S&W Model 39 pistol. The barrel has been re-bored to fire breech-loaded .50 caliber dart rounds, and the magazine well reconfigured to hold a compressed air canister (good for 50 shots). The weapon must be reloaded with a new dart after every shot. 

Desert Eagle 

If you saw a handgun in a movie, and it wasn’t an M1911 or M1911 clone, it was probably a Desert Eagle, most likely outfitted with a tacky chrome finish and gigantic laser aiming module. Far less common in real life than in the movies, the inimitable Desert Eagle is almost certainly too much firepower for any given situation. The Desert Eagle is a large-bore gas-operated semi-automatic pistol designed by Magnum Research in the U.S., and manufactured primarily in Israel by IMI. This monster has been available since 1985. 

HK Mk. 23 Mod 0 

The Heckler & Koch MK23 Mod 0 is a handgun consisting of a match grade semi-automatic pistol, a laser aiming module (LAM), and suppressor. It was adopted by the United States Special Operations Command (USSOCOM) for special operations units in the 1990s. While the designation applies to the complete system, it's also commonly used in reference to the pistol component itself. A deadly and effective weapon, designed in 1991. 


Produced between 1985 and 1994, the Intratec TEC-DC9 (also known simply as the TEC-9) is a blowback-operated, semi-automatic firearm, chambered in 9×19mm Parabellum, and classified by the U.S. Bureau of Alcohol, Tobacco, and Firearms as a handgun. It is made of inexpensive molded polymers and stamped steel parts. The TEC-9 was not accepted by any armed forces leading to its use as a civilian gun and eventually a crime gun, infamously associated with gang violence in south-central Los Angeles, since it can be easily and illegally converted to an automatic weapon. The TEC-9 was listed among the 19 firearms banned by name in the USA by the 1994 Federal Assault Weapons Ban. Their small size made them difficult to fire accurately in full auto, and this, when combined with their high rate of fire, made control challenging; this was a key factor in their never finding much success with the military. 


The Uzi (Hebrew: עוזי‎, officially cased as UZI) is a related family of open bolt, blowback-operated submachine guns; these stats represent a full-sized SMG. The Uzi was one of the first weapons to use a telescoping bolt design which allows for the magazine to be housed in the pistol grip for a shorter weapon. The Uzi has found use as a personal defense weapon by rear-echelon troops, officers, artillery troops and tankers, as well as a frontline weapon by elite light infantry assault forces. The first Uzi submachine gun was designed by Major Uziel Gal in the late 1940s. 

Beretta 93R 

Designed in 1970 and produced only until 1990, the Beretta Model 93R is a selective-fire machine pistol made by the Italian Beretta company and derived from their semi-automatic Model 92. The “R" stands for Raffica which means “burst" in Italian. The pistol was designed in the 1970s and was meant for police and military use, offering extra firepower in a small package, and is suited for concealed carry purposes such as VIP protection, or for close quarters fighting such as room-to-room searches. A selector switch and the foldable foregrip allows the pistol to fire three round bursts with each pull of the trigger for a cyclic rate of 1100 rounds per minute. The designers limited it to fixed three-round bursts to allow it to be more easily controlled. The 93R is basically a Beretta 92 series pistol, but the 93R is single action and outfitted with a muzzle brake, an optional detachable shoulder stock, and a 20-round magazine that also allows for a firmer grip. 


The AK-47 (or Avtomat Kalashnikova) is a selective fire, gas operated 7.62mm assault rifle developed in the Soviet Union by Mikhail Kalashnikov in the 1940s. Six decades later, the AK-47 and its variants and derivatives remain in service throughout the world. It has been manufactured in many countries and has seen service with regular armed forces as well as irregular, revolutionary and terrorist organizations worldwide. In some third world countries, an AK is available on the black market for less than fifty dollars. Designed in 1946 and still being produced. 


Designed in 1957 and in service from 1964 to the present, the M16 (more formally Rifle, Caliber 5.56mm, M16) is the U.S. military designation for the ArmaLite AR-15 rifle. Colt purchased the rights to the AR-15 and currently uses that designation only for semi-automatic versions of the rifle. The M16 entered United States Army service as the M16A1 and was deployed for jungle warfare in the Republic of South Vietnam in 1963, becoming the standard US Rifle of the Vietnam War by 1969 – replacing the M14 rifle in that role. Since the Vietnam War, the M16 rifle family has been the primary infantry rifle of the U.S. military. With its variants, it has been in use by 15 NATO countries, and is the most produced firearm in its caliber. The M4 is a shorter, lightweight carbine version of the M16, which is, in terms of its stats in this game, functionally identical. 


Developed in 1964 and still manufactured today, the Heckler & Koch MP5 (From Maschinenpistole 5 - German: “machine pistol model 5") is a 9mm submachine gun of German design, developed in the 1960s by a team of engineers from the German small arms manufacturer Heckler & Koch GmbH (HK) of Oberndorf am Neckar. It is currently used by the armed forces and law enforcement units of over 40 countries, and is a mainstay of SWAT teams and special forces units. The MP5 remains one of the most widely deployed of all current submachine guns and has been developed into a family with numerous variants. 

UMP 45 

The UMP is a blowback operated, magazine-fed submachine gun firing from a closed bolt. As originally designed, the UMP is chambered for larger cartridges than other submachine guns like the MP5, to provide more stopping power against unarmored targets (with a slightly lower effective range) than the 9×19mm MP5 provides. A larger cartridge produces more recoil, and makes control more difficult in fully automatic firing. To mitigate this, the cyclic rate of fire was reduced to 600 rounds/min for the UMP45, which makes it one of the slower firing submachine guns on the market. Its predominantly polymer construction reduces both its weight and the number of parts susceptible to corrosion. When the last round of the UMP is fired, the bolt locks open, and can be released via a catch on the left side. The standard viewing sights comprise an aperture rear sight and a front ring with a vertical post. It can mount four Picatinny rails (one on top of the receiver, and one on the right, left, and the bottom of the handguard) for the attachment of accessories such as optical sights, flashlights, or laser sights. Vertical foregrips can be attached to the bottom rail for increased controllability during burst and automatic fire. 

FN P90 

The FN P90 is a selective fire personal defense weapon (PDW) designed and manufactured by FN Herstal in Belgium. The P90's name is taken from 1990, the year it was introduced. The P90 was created in response to NATO requests for a replacement for 9×19mm Parabellum firearms; it was designed as a compact but powerful firearm for vehicle crews, operators of crew-served weapons, support personnel, special forces, and counter-terrorist groups. The P90 was designed by FN in conjunction with the FN Five-SeveN pistol and FN 5.7×28mm ammunition. The P90 was developed and initially marketed as a personal defense weapon, but it could also be considered a submachine gun or compact assault rifle. Featuring a compact bullpup design with an integrated reflex sight and fully ambidextrous controls, the P90 is an unconventional weapon with a futuristic appearance. Its design incorporates several innovations such as a unique top-mounted magazine and FN's small-caliber, high-velocity 5.7×28mm ammunition. The P90 is currently in service with military and police forces in over 40 countries, such as Austria, Brazil, Canada, France, Malaysia, Poland, and the United States. In the United States, the P90 is in use with over 200 law enforcement agencies, including the U.S. Secret Service. 


FAMAS stands for Fusil d'Assaut de la Manufacture d'Armes de St-Etienne. Development of this rifle began in 1967, under the leadership of the Paul Tellie, a French arms designer. This new rifle was intended to replace in service the MAS Mle.49/56 semi-automatic rifles, MAT-49 submachine guns, and some MAC Mle.1929 light machine guns. The FAMAS rifle was adopted by the French in 1978 and since then became a standard French Army shoulder-fired small arm, known among the French soldiers as “Le Clairon" (the bulge). It is still used by the French army, and was exported in small numbers to some countries like the Senegal or United Arab Emirates. The FAMAS G2, which appeared circa 1994, has the G1-style enlarged trigger guard but can accept only STANAG type (M16-compatible) magazines. It was adopted and purchased by the French Navy in the 1995, with the French Army soon following suit, and also offered for export. At the present time, the slightly upgraded FAMAS G2 rifle is used as a platform for the future FELIN system (a French counterpart to the US “Land Warrior" program), which incorporates various electronic sights and sensors connected to soldier-carried equipment such as helmet mounted displays, ballistic and tactical computers, etc. GIAT also now offers some variations of the basic FAMAS G2 rifle, such as “Submachine Gun" (with a shortened receiver and 320mm-long barrel), “Commando" (with the standard receiver and the 405mm barrel), and the “Sniper" (with a longer and heavier 620mm barrel and an integral scope mount instead of the carrying handle). 


First available in 1977, the AUG is an Austrian bullpup 5.56mm assault rifle, designed in the early 1970s by Steyr Mannlicher GmbH & Co KG. In production since 1978, it is the standard small arm of the Austrian Bundesheer and various national police units. The rifle has also been adopted by the armed forces of Argentina, Australia, Bolivia, Ireland, Saudi Arabia, Tunisia (introduced in 1978), Pakistan, and – since 1988 – U.S. Customs. 

Remington 700 

First manufactured in 1962, the model 700 series of firearms are bolt-action hunting rifles. All are based on the same centerfire bolt action. The Model 700 is available in a great number of different stock, barrel and caliber configurations. It is a development of the Remington 721 and 722 series of rifles, which had been introduced in 1948. This particular specimen has a wooden stock and is chambered for the middle-of-the-road .223 round. 

ArmaLite AR-15/Ruger Mini-14 

A favorite of survivalists and gun-fanatics, the AR-15 is a demilitarized, civilian version of the M-16 assault rifle. Standard AR-15 rifles accept detachable magazines of widely varying capacities, and have a pistol grip that protrudes beneath the stock. AR-15 rifles are highly configurable and customizable. They are commonly fitted with several accessories such as bipods, folding or collapsing stocks, threaded barrels for the attachment of a flash suppressor, and a rail system for the attachment of vertical grips, flashlights, laser sights, telescopic sights, etc. The AR-15 rifle is available from 1958 to the present. 

Ithaca 37 

First produced in 1937, the Ithaca 37 is a classic 12 gauge pump-action shotgun used by hunters and law enforcement professionals for decades, and made in large numbers for the civilian, military, and police markets. Also known as the Featherlight, it utilizes a novel combination ejection/loading port on the bottom of the gun which leaves the sides closed to the elements. In addition, the outline of the gun is clean. Finally, since shells load and eject from the bottom, operation of the gun is equally convenient from either side of the gun. This makes the gun popular with left-handed and right-handed shooters alike. 


This recurve crossbow features a black synthetic stock and fiberglass limbs that offer pure performance. The 14" power stroke with a 150lb. draw weight delivers arrow speeds of up to 365 FPS with a 16" aluminum arrow. Features built-in adjustable sights and a rail-mounted scope for precision accuracy. Animal control officers and bounty hunters use these crossbows with syringe bolts for long-range live capture. 

Remington Model 30 

Produced from 1921 to 1941, the Remington Model 30 is a US sporting rifle of the inter-war period based on the military P14/M1917 Enfield rifle action, which was manufactured for the British and US governments during World War I. Most early rifles were in the military .30-06 caliber used in the M1917 but it became available in a variety of chamberings. It was the first high-powered bolt-action sporting rifle produced by Remington. These statistics are representative of other powerful .30-.06 hunting rifles. 

Tranquilizer Rifle 

This CO2 rifle from DAN-INJECT fires a compressed-air powered syringe dart from a .50 caliber smooth-bore barrel. Compact and reliable, with synthetic furniture and a weather-resistant anodized aluminum barrel and stainless steel fixtures. As the manometer and telescopic sight can be viewed simultaneously, pressure adjustment is rapidly and silently achieved without the operator losing sight of the target. 

Sawn-Off Double-Barreled Shotgun 

The #1 choice for zombie killin’, unless of course you can rig up one with four side-by-side barrels. This is essentially a Ruger Gold Label (or any number of identical side-by-side break action hunting shotguns) with a sawn-off stock for a pistol grip, and a sawn-off barrel for improved close-quarters handling, concealability, and close-range spread. 

Mossberg 590 

Produced from 1961 to the present, the Mossberg 500 is a shotgun manufactured by O.F. Mossberg & Sons. Rather than a single model, the 500 is really a series of widely varying hammerless, pump action repeaters, all of which share the same basic receiver and action, but differ in bore size, barrel length, choke options, magazine capacity, and “furniture" (stock and forearm) materials. The Model 590A1 is a Model 590 with an aluminum trigger guard and safety, and a heavier barrel, intended for military use under extreme conditions and rough handling; the metal trigger guard was added in response to the 3443G materials requirements, and the heavy barrel was added at the request of the Navy. The 590A1 is generally sold through military and law enforcement channels, though in most jurisdictions the 18.5-inch (47 cm) and 20-inch (51 cm) models may be legally purchased by private persons. 

CheyTac Intervention 

The CheyTac Intervention is an American bolt action sniper rifle manufactured by CheyTac LLC for long range interdiction. It is fed by a detachable single stack magazine, which holds 7 rounds. It fires .408 CheyTac or .375 CheyTac ammunition. CheyTac papers state that the entire system is capable of delivering sub-MOA accuracy at ranges of up to 2,500 yards (2,300 m), one of the longest ranges of all modern-day sniper rifles. The CheyTac muzzle brake suppressor, manufactured by OPS INC, is a stainless steel suppressor. The all stainless steel construction with no replaceable parts guarantees a suppressor life that equals or exceeds the life of the rifle. The primary sight is the Nightforce NXS 5.5-22×56 variable magnification telescopic sight with a 56mm objective. The night vision system chosen is the AN/PVS-14 GEN III Pinnacle monocular. The PVS-14 is attached to the day optic using the Monoloc device. An AN/PEQ-2 infrared laser is used for system support with the night vision sight under conditions where there is insufficient ambient light or the IR laser is needed for further target illumination. The device is attached to a titanium strut. A Vector IV mil spec laser rangefinder is used to establish ranging data. This laser rangefinder can measure distance up to 6 km (3.7 mi), angles and also features a 360° digital compass and class 1 eye safe filters. The Intervention holds the world record for best group at a distance, landing 3 bullets within 16⅝ inches (42 cm) at 2,321 yards (2,122 m). 


The Dragunov sniper rifle is a semi-automatic sniper rifle chambered in 7.62×54mmR and developed in the Soviet Union. Since then, the Dragunov has become the standard squad support weapon of several countries, including those of the former Warsaw Pact. 


The RPG-7 is a widely-produced, portable, shoulder-launched, anti-tank rocket-propelled grenade weapon. Originally the RPG-7 and its predecessor, the RPG-2, were designed by the Soviet Union, and are now manufactured by the Bazalt company. The ruggedness, simplicity, low cost, and effectiveness of the RPG-7 have made it the most widely used anti-tank weapon in the world. Currently around 40 countries use the weapon, and it is manufactured in a number of variants by nine countries. It is also popular with irregular and guerrilla forces. The RPG has been used in almost all conflicts across all continents since the mid-1960s from the Vietnam War to the present day War in Afghanistan and Iraq War. 

L86 LSW 

The development of the SA-80 (Small Arms family for 1980s) was started in Britain by the late 1960s, with the search for the “ideal" small-bore ammunition. The LSW was based on the SA-80 IW design. The final version of the SA-80 LSW was adopted by the British Army in 1986, and slightly over the 22,000 LSW weapons were manufactured before the production of both L85 IW and L86 LSW was ceased. The L86A1 was plagued by the same problems as its sister, the L85A1 rifle. In fact, the L86A1 was more suitable as a semi-automatic para-sniper rifle than the LSW / LMG, due to the poor reliability in full automatic fire, relatively small (by machine guns standards) magazine capacity, and the lack of quick detachable barrels. Current British troops prefer much heavier and belt-fed 7.62mm L7A1 GPMG (a license-built copy of Belgian FNMAG general purpose machine gun), and at the present time, the existing stocks of L86A1 are complemented with the 5.56mm FN Minimi belt-fed LMG in the short-barreled Para configuration. The L86A1 will be used mostly as a longer-range aimed fire weapon, while the suppressive fire functions will be conducted using the more effective FN Minimi. General design of the L86A1 is mostly similar to the design of L85A1 rifle, except for the following: the L86A1 has a longer barrel, with the steel stock extension under it, which carries the folding bipods; the bolt and trigger system are modified, so the gun can be fired from open bolt; the butt is fitted with folding shoulder support; the vertical grip is attached below the receiver, behind the magazine housing; the L86A1 could not be fitted with bayonet. 

M79 Grenade Launcher 

First available in 1960, The M79 grenade launcher is a single-shot, shoulder-fired, break-action grenade launcher which fires a 40×46mm grenade, and first appeared during the Vietnam War. Because of its distinctive report, it earned the nicknames of “Thumper", “Thump-Gun", “Bloop Tube", and “Blooper" among American soldiers. The M79 can fire a wide variety of 40mm rounds, including explosive, anti-personnel, smoke, buckshot, flechette, and illumination. While largely replaced by the M203, the M79 has remained in service in many units worldwide in niche roles. 


The RPD (Russian: ручной пулемёт Дегтярёва – Ruchnoy Pulemyot Degtyaryova; English: hand-held machine gun of Degtyaryov) is a light machine gun developed in the Soviet Union by Vasily Degtyaryov for the intermediate 7.62×39mm M43 cartridge. It was created as a replacement for the DP machine gun chambered for the 7.62×54mmR Mosin rifle round. It is a precursor of most squad automatic weapons. The RPD is an automatic weapon using a gas-operated long stroke piston system and a locking system recycled from previous Degtyaryov small arms, consisting of a pair of hinged flaps set in recesses on each side of the receiver. The weapon fires from an open bolt. The RPD is striker fired and features a trigger mechanism that is limited to fully automatic fire only. The bolt is equipped with a spring-loaded casing extraction system and a fixed insert inside the receiver housing serves as the ejector. Spent cartridge casings are ejected downward through an opening in the bolt carrier and receiver. Like many other rugged Russian-made firearms, the chamber and bore are chrome-lined, greatly decreasing the risk of corrosion and jamming. The weapon has a non-removable barrel with a 3-position gas adjustment valve used to control the performance of the gas system. It is also equipped with a folding integral bipod, wooden shoulder stock, foregrip and pistol grip. The firearm strips down into the following major groups: the receiver and barrel, bolt, bolt carrier, feed tray and feed cover, the recoil mechanism and the trigger group and stock. The machine gun feeds from the left-hand side from a segmented, open-link metallic belt (each segment holds 50-rounds). Two combined belts (linked by cartridge), containing a sum total of 100 rounds are stored in a metal container resembling a drum, are attached to the base of the receiver. The LMG is equipped with a set of open-type iron sights. 


Designed in 1968, The M203 is a single shot 40mm grenade launcher that attaches to many rifles, but was originally designed for the U.S. M16 and its variant, the M4 Carbine. In the U.S. military, when a rifle or carbine is equipped with the launcher, both weapons are collectively referred to as an M203. Stand-alone variants exist as do versions capable of being used on many other rifles. 


The M60 (formally the United States Machine Gun, Caliber 7.62mm, M60) is a family of American general purpose machine guns firing 7.62×51mm NATO cartridges from a disintegrating belt of M13 links. There are several types of live ammunition approved for use in the M60, including ball, tracer, and armor-piercing rounds. Introduced in 1957, it has served with every branch of the U.S military and still serves with other armed forces. Its manufacture and continued upgrade for military and commercial purchase continues into the 21st century, though it has been replaced or supplemented in most roles by other designs, notably the M240 in U.S service. 

Barrett M90 

The Barrett M90 is a bolt-action, bullpup sniper rifle, chambered in the massively powerful .50 BMG (12.7×99mm) round, and designed by Barrett Firearms Company. The M90 was designed and produced from 1990 to 1995 as a bolt-action alternative to the semi-automatic Barrett M82. It is a bolt-action rifle in a bullpup design. The weapon features a fluted barrel with integrated muzzle brake, 2 part receiver (upper and lower), folding bipod, and a 5-round detachable box magazine. The M90 has no iron sights, but instead has a Picatinny rail for the mounting of a scope. In 1995, Barrett stopped production of the M90, and replaced it with the M95 (same game statistics). 

Barrett M82 

Designed in 1980, the M82 (also more recently known as the M107) is a recoil-operated, semi-automatic anti-materiel rifle developed by the American Barrett Firearms Manufacturing. A heavy SASR (Special Application Scoped Rifle), it is used by many units and armies around the world. It is also called the “Light Fifty" for its .50 caliber BMG (12.7mm) chambering. In layman's terms, a gigantic anti-vehicular sniper rifle.
