Metal Gear Solid: Portable Ops
Metal Gear Solid: Portable Ops, is an action-adventure stealth video game developed by Kojima Productions and published by Konami in 2006 exclusively for the PlayStation Portable (PSP). Metal Gear Solid: Portable Ops Plus (officially abbreviated MPO+), the game's stand-alone expansion focused primarily on online play, was released for the PSP in 2007 in Japan and in 2008 in other regions.
MPO is the third Metal Gear title made specifically for the PSP (counting the two Acid turn-based games but not Metal Gear Solid: Digital Graphic Novel, since the latter was not a game) and the first one to retain the series' action-based play mechanics. It is set in the same continuity as the mainline Metal Gear series, though it is dubious as to what extent it is part of the main timeline as Hideo Kojima, who neither directed nor wrote it, was notably not fond of it and has stated some parts of it do not fit. Set in Colombia in 1970 on a fictional peninsula named San Hieronymo, six years after the events of Metal Gear Solid 3: Snake Eater, the game follows the exploits of Naked Snake after his former unit, FOX, goes renegade. The game also chronicles the eventual founding of FOXHOUND and The Patriots, as well as the inspiration of the military state Outer Heaven.
The following weapons appear in the video game Metal Gear Solid: Portable Ops:
Mk 22 Mod 0 "Hush Puppy"
A tranquilizer gun based on the S&W Model 39 pistol using 9mm tranquilizer ammunition. It's fitted with a suppressor. This is the first weapon the player acquires in the game. The ideal gun for tranquilizing enemies for recruitment or neutralization. Can be procured at the Ravine after receiving a spy report.
A .45 ACP semi-automatic pistol, it holds seven rounds. Female officers only use this weapon and some certain male soldiers and officers. Can be procured at the Communications base via a Spy Report.
Colt Single Action Army
The Colt Single Action Army appears once again as Ocelot's weapon of choice; the ricochet ability from previous games is maintained. He also uses it in the main story to take out the CIA director and his bodyguards nearing the ending, and presumably also left it behind to frame his death as a suicide.
Heckler & Koch Mark 23 Phase II Prototype
Portable Ops Plus exclusive. A semi-automatic handgun fitted with a suppressor and laser sight. Can be obtained by recruiting Raiden or by completing the hidden mission during the Extreme difficulty.
Portable Ops Plus exclusive. A SMG using 5.7x28 mm rounds, Bullpup style gun. Holds 50 rounds per magazine. Can be obtained from Tengu soldiers.
A 45. ACP caliber SMG with a high-rate of fire. Used by Null in combination with his Machete in game. Equipped with a suppressor. Can be obtained at the Power Substation via a Spy Unit Report.

Sa. Vz.61 Skorpion
A 32.ACP caliber SMG; it is equipped with a laser-aiming module for targeting. Can be procured at the Supply Depot via a Spy report.
An ambidextrous 12-gauge shotgun; holds four rounds. It can be procured at the Rail Bridge if a Spy Unit stationed there finds and reports it's location.
A 12-gauge shotgun; a step up from the Ithaca 37 by holding seven rounds. Can be procured at the Airport after receiving a spy report from a spy unit stationed there.
American made 5.56x45mm assault rifle, commonly used by the military. Holds 20 rounds per magazine. Can be procured at the Soviet Patrol Base via the Spy Unit. The character Python also carries the weapon during his boss fight, although not when he's a playable character.
M203 grenade launcher
A customizable grenade launcher placed underneath the barrel of various assault rifles, including the M16. Although not actually used by the player, it was equipped on Python's M16A1 during the boss fight against him. Unsurprisingly, it fires liquid nitrogen grenades, which instantly freezes any weapons the player has on them.
Colt XM177/CAR-15/Commando Series
A carbine version of the M16; the barrel and butt of the rifle both have been shortened, fitted with a silencer and has 30 round magazines. One of the many weapons used by FOX soldiers and exclusive only to them.
Portable Ops Plus exclusive. American made modern carbine rifle using 5.56x45mm rounds. 30 rounds per magazine. Can be obtained from a Navy SEAL or High-Tech soldier. The game lists this weapon as an M4, but its fully automatic fire makes it an M4A1, not an M4, which is limited to semiautomatic and burst-fire only.
Portable Ops Plus exclusive. Uses 5.56x45mm. Fitted with a foregrip. Can be obtained after recruiting Old Snake.
Soviet-made 7.62x39mm assault rifle, standard issue for the Soviet soldiers, developed in 1947. Used by all Soviet male soldiers. Holds 30 rounds per magazine.

Mosin Nagant M91/30
A Soviet bolt-action rifle deployed in large numbers in the Second World War, however it fires modified 7.62x54mmR tranquillizer darts in-game holding 5 rounds per magazine. Players of Metal Gear Solid 3: Snake Eater may recognize this weapon used by The End. The player must use this weapon at an appropriate range and be more careful with their aim as this weapon is not silenced like the MK22 and has a lower firing rate between shots. The scope has thick crosshairs making it suitable for use at night. Can be procured at the Nuclear Warhead Storage Facility via a Spy Unit Report.
A semi-automatic Soviet sniper rifle holding 10 7.62x54mmR rounds per magazine. It can be procured in the Western Wilderness via a Spy Unit Report.
A light machine gun variant of the M63 weapons system; fires 5.56x45mm ammo. Has 100 rounds per box magazine. Cannot be viewed from its iron sights. Although lacks accuracy this weapon is effective against machines and large numbers of enemies. It can be procured at the Harbor if a Spy Unit stationed at the area finds and reports it.
M1919 Browning Machinegun
Although not acquirable by the player, the M1919 was utilized by Metal Gear RAXA during the boss fight against it. Dialogue from Snake when uncovering some evidence of what was in the shipping container implied that the ICBMG, the actual Metal Gear threat in the game, also carried the same weapon system.
Soviet-made rocket propelled grenade launcher using 85mm HEAT ammunition ideal for anti-tank and anti-air use. Mobility is lost when deployed. Triggers alert mode upon impact. The player can view down the attached scope instead of locking-on or view from first-person as a shoulder-fire weapon.
