Soldier of Fortune II: Double Helix
The following weapons appear in the video game Soldier of Fortune II: Double Helix:
The M1911A1 is the first handgun you are given in the game. Has a 7-round magazine and can also be dual-wielded. It appears to have some custom features, such as a 'combat'-style hammer and dot sights.
Heckler & Koch Mark 23 Mod 0
The Heckler & Koch Mark 23 is the main recommended sidearm on the 'loadout' screen before missions, first available to select on said loadout screen before the start of the Columbia levels. It has a 12-round magazine, and is available with either a rail-mounted flashlight, the Laser-Aiming Module (LAM), or with the suppressor mounted. Can also be dual-wielded.
IMI Desert Eagle Mark XIX
A chromed Desert Eagle Mark XIX named the "Silver Talon" like Soldier of Fortune is available as a sidearm in multiplayer, and in singleplayer with 'Give All' cheat or the Gold Edition. As with the other handguns, it can also be dual-wielded.. The in-game weapon features a non-fluted barrel indicating it was modeled after a .50AE variant. . Despite the different calibers, this weapon uses the same .45 ACP ammo stock as the 1911A1 and Mk23 pistols. It has a 7-round magazine.
Mossberg 590 Cruiser
The first and main shotgun encountered in the game is the Mossberg 590 Cruiser. First found in one of the Prague levels. Available afterward for equipment loadouts before starting missions. Wielded by enemies throughout the game, most notably in the Columbia mission levels. Carries 9 shells in the magazine tube.
The USAS-12 Shotgun is the only other shotgun in-game. Available in later mission loadouts, and used by some enemies, mainly in the Hong Kong levels. Can be fired semi-automatic or fully-automatic, and uses 10-round box magazines. Quite difficult to control when fired on full-auto.
IMI Micro Uzi
The main SMG encountered in-game is the Micro Uzi. Available in later mission loadouts, used a lot by enemies in the Hong Kong and Seaward Star mission levels. Uses 30-round magazines and can be dual-wielded. Very inaccurate when fired in long full-auto bursts.
M3A1 "Grease Gun"
The M3A1 'Grease Gun' is the first automatic weapon you will receive, used by enemies in the Prague mission levels. The weapon has a conical flash-hider. The weapon (correctly) uses the same .45 ACP ammo stock as the handguns, giving it a lower max ammo amount than other automatic weapons. It is fairly accurate and controllable, but slow-firing.
Heckler & Koch MP5A5
The final SMG in-game is the Heckler & Koch MP5A5, simply called "MP5" in the game, fitted with sound suppressor (The weapon's animation always shows fitting the suppressor on when you ready the weapon, however it can not be attached/removed manually). Can fire in semi-automatic, three-round burst, and fully-automatic. Available as a primary weapon in multiplayer or with 'Give All' cheat or Gold Edition in singleplayer. Has 30-round magazine capacity but is shown using straight magazines. Despite it being a 'suppressed' weapon, the in-game P.A.D.D. (Personal Audio Detection Device) shows that it is as noisy as other non-silenced weapons.
Colt Model 727 with M203 Grenade Launcher
The Colt Model 727 appears as "M4" in the game. This is the recommended primary weapon in pre-mission loadouts until the introduction of the OICW. It can fire in semi-auto, 3-round burst, or full-auto. Alternate fire fires the mounted M203 grenade launcher. Uses 30-round magazines. Used by many enemies much later in the game.
The AK-74 is a common assault rifle heavily used by enemies throughout the game. The AK-74s in this game are stated to have been converted from the standard 5.45x39mm to 5.56x45mm NATO. As such, they use the same 5.56 ammo stock as the 5.56mm rifles in the game. Like all other assault weapons in-game, this weapon fires in semi-auto, three round burst, or full-auto. A separate version of the rifle is available with a non-detachable bayonet.
SIG SG 551
Another available assault rifle is the SIG SG 551, fitted with an unknown 3x scope. Uses 30-round magazines. Can be fired in semi-auto, 3-round burst, or full-auto. Available as a primary weapon in multiplayer or with 'Give All' cheat.
Heckler & Koch XM29 OICW
The Heckler & Koch XM29 Objective Individual Combat Weapon is used in the single-player game, becoming available after Mullins tests it out at 'The Shop', some ways into the game. It uses 30 round magazines for the 5.56 rifle part of the weapon, firing in either semi-auto, 3-round burst, or full-auto. After it is available, it surpasses the M4 W/M203 as the recommended primary weapon.
The weapon in the game has a multi-purpose sight, that can be used as a sniper scope (with night-vision and up to 20x magnification), can identify targets with friend-foe type recognition, and acts as the range calculator for its grenade launcher.
The game attempts to simulate the complex HEAB (high explosive air burst) functionality of the real weapon. The grenade rounds must be lased at a point downrange, but once lased, are shot normally; they will explode at the displayed distance, which can be adjusted manually with two of the alt-fire keys, and the sight provides a marker indicating the elevation required to land a grenade at the lased distance. This allows the player to, for example, lase a wall, increase the distance slightly and fire over it to have the grenade explode in mid-air just behind it. The sight must be used with the 'lase' to fire the launcher, making it rather awkward to actually use in the game; this is not a feature of the real OICW, which could also fire grenades in impact-detonation mode. The grenades are fired from 6 round magazines and are not interchangeable with the grenades for the M203 or MM1; realistic, since the 20mm launcher on the OICW would not be able to chamber a 40mm grenade.
The RPD light machine gun is seen as a fixed/mounted weapon in the Prague levels.
The M60 machine gun is available as a second main weapon for single-player loadouts, and also seen as a fixed/mounted weapon in parts of the game. It is quite powerful, but fires quick and depletes ammunition fairly rapidly. The carryable version of the weapon uses 99-round belts fed from an attached ammo box. Notably, two of the sub-bosses carry an M60.
Heckler & Koch MSG90A1
The Heckler & Koch MSG90A1 is the main sniper rifle in-game, weapon available quite early on, and used by enemies throughout the game. Despite being shown using what appear to be 20-round magazines, mag-capacity on the weapon is only 5-rounds. The weapon also does not contain a bipod. The MSG90 is also the weapon of choice for "Deviant 1" at the end of the Hong Kong mission.
The MM1 multiple grenade launcher is available as a primary 'heavy' weapon on mission loadouts starting with the Seaward Star mission. It fires a drum of 10 grenades, all loaded individually. It uses a different 40mm grenade ammo pool than the M203 grenades.
The RPG-7 is also available as a primary 'heavy' weapon on mission loadouts in multiplayer.
The M67 hand grenade is the standard US explosive fragmentation grenade, available on mission loadouts.
The L2A2 fragmentation grenade, found and used by enemies mainly on the Hong Kong mission levels.
The AN/N14 is an incendiary grenade, spewing a blast of flame when thrown. Available later in the game on mission loadouts.
The M15 WP Smoke Grenade, available in later mission loadouts, not only acts as a smoke grenade, but also can be used offensively, blasting WP (White Phosphorus) particles on enemies. It is a slightly bizarre inclusion as the grenade was retired in favour of the M34 in the 1950s.
M84 Stun Grenade
The M84 stun grenade or 'Flash-Bang' grenade is available very late in the game on mission loadouts. When thrown, it makes a deafening noise and blinding flash when it goes off. Will temporarily stun and neutralize enemies without killing them.
Swedish 'offensive' fragmentation grenade.
German hand grenade,and heavily use by enemies at the later in this game.
