Syphon Filter 2

The below weapons were used in Syphon Filter 2.

Assault rifles

M-16

Usable in most missions.

Heckler and Koch G11

The G11 is a bizarre weapon, firing rounds from a magazine containing 50 bullets. This technically makes it a standard assault rifle, but it has a strange 'zoom' scope that allows for precision shots. This, despite its blazing fast fire rate.

"PK102"

A "PK102" can be used in game.

"K3G4"

As was the case in the first game, this is a fictional weapon which is apparently some kind of one-handed AK pistol without a handguard, but is still classified as a rifle. Also like Syphon Filter, its description repeats the media myth of the "teflon-coated bullet": while heavy AP rounds do have Teflon coatings to reduce barrel wear, the coating is mostly removed through contact with the weapon's rifling and has no effect on its penetration. Despite its armour-piercing performance in-game, it does not stop Gabe from recovering completely intact armour pickups.

Submachine guns

Heckler & Koch MP5SD

The "HK5" is now a Heckler & Koch MP5SD rather than an MP5K as it was in the first game. It is used by both the player and enemies, including Emergency Defense personnel sent into the Agency Bio-labs to stop Gabe from escaping, as well as Jason Chance, an undercover operative apparently working for the Chemical Biological and Defense Command (but in fact employed by the Agency), when he shoots Teresa Lipan before the last mission.

Apparently this weapon has both an integral suppressor AND an extended magazine.

Bizon

The Bizon can be used in game. As was the case in the first instalment, each magazine holds 60 rounds or more.

Shotguns

12 gauge shotgun

A single-shot weapon that is devastating up close.

How the jolly hell does a weapon WITHOUT a magazine capacity have a maximum number of rounds?!

Daewood Precision Industries Universal Sporting Automatic Shotgun

The USAS-12 can be used; this marks the first time the Syphon Filter series contains the weapon. It would be used in all the next games. The weapon is notable for being required to defeat Jason Chance, the last boss, without accidentally destroying the helicopter. Coincidentally, Chance himself wields the same firearm despite being armed with an MP5 in the cutscene immediately before this mission.

Once again, the USAS suffers from the very same mistake that the shotgun is also prone to: it has no magazine capacity yet there is a cap on the number of bullets one can carry.

Sniper rifles

SIG SG 550 SR

A general purpose sniper rifle may be used in the game.

SVD Dragunov

Almost exactly the same as the usual sniper rifle but this one has a night vision sight.

Pistols

Colt .45

The M1911 can be found and used.

Apparently in this universe the year 1911 came after the year 1914. Note also the incorrect assertion that the classic M1911 design is double-action.

Glock 17

Machine pistols

Glock 18

Launchers

DefTech 37mm launcher

A DefTech 37mm launcher firing CS gas grenades can be used. Oddly, the maximum number of rounds that can be carried is 5, meaning Gabe cannot even fully load the 6-round cylinder.

Defense Technologies/Federal Laboratories launcher 37mm with folding stock

Tru Flite 37mm Super Long Range Gas Gun

The weapon called the "M79" in-game is actually a Tru Flite 37mm Super Long Range Gas Gun incorrectly shown as able to launch high-explosive grenades.

Tru Flite 37mm Super Long Range Gas Gun - 37mm

Explosives

Soman nerve agent

Incendiary grenade

Miscellaneous

Crossbow
