Weapons of Syphon Filter: Combat Ops

The weapons used in Syphon Filter: Combat Ops are as follows.

General Overview

Although multiplayer modes have existed in the previous Syphon Filter games, this title is so far the only game that solely contains multiplayer activities, in other words, it has no storyline whatsoever. Players can select five different slots, a convention first started in The Omega Strain.

Special - this is a unique weapon. All players will ONLY have the choice of a sniper rifle that can fire regular bullets as well as 'darts' that can be triggered to fire at any point.
Back - this contains assault rifles, carbines, machine guns, shotguns, launchers, sniper weaponry etc, and therefore has the largest quantity of options available.
Sidearm - this is obviously a pistol category
Auxiliary - referring to submachine guns, and short rifles or certain carbines.
Grenade - explosives or other area denial weapons, such as smoke canisters, incendiary molotovs, gaseous weapons etc

Very few weapons exist at the lowest rank but more options are available as a player is promoted. A default weapon all the participants of a match receive, regardless of rank or faction, is the long-range taser (EPDD) available from the original Syphon Filter, which made the franchise so infamous.

Pistols

Heckler & Koch Mark 23 SD

As in the Logan's Shadow multiplayer, the standard weapon of Gabe Logan can be used by everyone.

Fabrique Nationale Five-seveN

The SP-57 is based on the Dark Mirror model with an incorrect magazine capacity of 10 bullets instead of 20 bullets.

Makarov PM

The Russian pistol appear once again. Unlike the previous appearances it has a 12-round magazine instead one of 8 bullets. It uses a Russian caliber, the 9x18 Makarov.

Desert Eagle Mark XIX

The Desert Eagle has two different calibers: the .357 Magnum and the .50 Action Express.

Heckler & Koch MP7

The weapon was available in Dark Mirror, where it could be dual wielded. However, this ability has been lost.

Sawed-Off Pistol

Glock G-17

Intratec Tec-9 (Ripper)

The fictional reproduction of the TEC-9 appears again in Combat Ops. It is equal in every aspect to the one seen in the Dark Mirror multiplayer, 20 bullets per magazine and less damage, but can be dual wielded.

Submachine Guns

Ingram Military Armament Corporation (MAC)-10

SITES Spectre M4

As the first appearance in Omega Strain, is called just Spectre.

IMI Uzi

Called UG9 in the European release of the game, appear in Combat Ops.

Heckler & Koch MP5A3

Shotguns

Daewoo Precision Industries USAS-12

Mossberg 500 Mariner Cruiser

The classic shotgun appeared in every game. It was called Shot Defender from Omega Strain and makes an appearance again.

SWD/Cobray Street Sweeper

Franchi SPA-12

The SPA-12 returns in Combat Ops and still isn't a Franchi SPAS-12. It is also not Browning Over and Under shotgun, but rather is a TOZ-34.

Sawed-Off Shotgun

This exclusive weapon to the multiplayer of Dark Mirror and Logan's Shadow returns also in this multiplayer-exclusive title. It is better than the Sawed-Off Pistol, but is an auxiliary weapon, so can't be dual wielded.

Launchers

Shoulder-launched Multi Purpose Assault Weapon (SMAW)

Unlike Dark Mirror single player appearance the SMAW can used by any player.

Milkor Multi Grenade Launcher (MGL) Mk

The MGL has a 4 grenades-per-cylinder capacity, so you can't have a fully loaded MGL once again.

M79

Using the model of Omega Strain, this is actually a true M79.

Milkor Multi Grenade Launcher (MGL) Mk firing smoke grenades

Assault Rifles

Galil AR

This 25 rounds rifle appears again.

Norinco Type 56

Called the Chinese Type 56, this is the Chinese reproduction of the Russian AK-47, with an increased magazine capacity and wood style parts, as seen in previous Syphon Filter games from Omega Strain.

FAMAS

This has a magazine capacity containing 25 rounds, and fires in single-shot or burst-fire.

AK-47

The AK-47 appears in Combat Ops.

Steyr Armee Universal Gewehr (AUG) HBAR

Colt M16A2

"Fictional M16K"

Ramat / TripBar

Colt M16 A2 with M203 grenade launcher (Over Under)

The Logan's Shadow new weapon appears also in Combat Ops. It is based on a Colt M16 that fires only in three round bursts and the M203 grenade launcher attached on the rifle fires grenades that explode on the impact. The weapon in-game mostly seems to resemble the M-16A2.

Sniper Rifles

SVD Dragunov

Barrett M82A1

Heckler and Koch MGS90 (MB-150)

Heckler and Koch MGS90 (C8 Rifle)

The Heckler and Koch MSG90 returns incorrectly referred to as the "C8 rifle" as was the case in The Omega Strain. It shares the same model as the "MB-150", but was infamous in TOS for having a 50-round drum magazine allowing it to be used at will as an assault or sniper instrument. Despite its callsign, it does not bear any relation whatsoever to the true Colt Canada C8.

Heckler and Koch PGS-1 (DSC-1 Thermal)

The thermal version was fully usable in Omega Strain in the Minsk mission, like any other weapon of Omega Strain returns in the multiplayer mode of the later games and if a player found it will be helped by the thermal scope, due the lack of thermal googles.
