Metal Gear Solid 3: Snake Eater/Weapons

Close Quarters Combat (CQC)
Close Quarters Combat is a special style of hand to hand fighting designed by Snake and The Boss.

Controls
 * Circle (repeatedly) - Initiates a combo attack that will knock enemies over.
 * Circle (hold) - Holding Circle while next to a guard will grab them. From here, you can do several different things:
 * Circle+Left stick - Push this in any direction while holding Circle to throw the guard to the floor, instantly knocking them out.
 * Left stick (after grabbing enemy) - Drags the enemy around. This is slow and your camo index will drop.
 * L3 - Threatens the enemy with your knife and interrogates them. You can obtain useful information, like locations of supply rooms, radio frequencies to disable alarms or unlock doors, or even tips to defeat bosses.
 * Circle (repeatedly) - Chokes the enemy to knock them out.
 * Circle (press firmly) - Slits the enemy's throat with your knife.
 * R1 - Enters First Person View, allowing you to aim and fire your pistol while using the grabbed enemy as a human shield.

Survival Knife
A serrated-edge combat knife designed to aid in survival in the jungle. Can cut all kinds of things. You can still use CQC attacks while equipped with this weapon.

Controls
 * Square (repeatedly) - Initiates a combo slash attack that will seriously injure or kill guards if all the attacks hit. Only useful if you need to get away during an Alert phase.
 * Square (press firmly, or while crawling) - Snake will stab forward, killing whatever he hits. Also useful for killing wildlife for food, or cutting down mushrooms to pick up.

Mk.22 Hush-Puppy tranqulizer pistol
A pistol modified to shoot tranquilizer rounds. Holds a maximum of 9 rounds (8 plus 1 chambered). The tranquilizer is most effective if aimed at an enemy's head - it will take longer to put an enemy to sleep if aimed elsewhere. You can use CQC attacks with this weapon.

Controls
 * Square (hold) - Aim the pistol. Most effective in First Person View.
 * Square (release quickly) - Fire the pistol. Because the slide locks, Snake will have to cock the pistol manually after every shot.
 * Square (release slowly) - Lowers the pistol without firing.
 * Circle (while in Weapon menu) - Attaches/removes suppressor.

Colt M1911A1 .45 pistol
A powerful handgun, and your first reliable method of killing enemies stealthily from a distance. Holds a maximum of 8 rounds (7 plus 1 chambered). It will also accept suppressors. You can use CQC with this weapon.

Controls are same as the Mk.22.

Colt Single-Action Army Revolver
The most powerful handgun available. Ocelot takes a liking to this variety, and you eventually get your hands on one of your own. Holts a maximum of 6 rounds and takes a while to reload. A unique feature of this gun is how the bullets will ricochet. Even if you miss, the bullet will ricochet in such a way that it will at least wound whoever is near. It's still preferable to be a good shot, because the bullet is much weaker after hitting a few walls.

Controls
 * Square - Hold to bring the gun into view.
 * L1 - Aims down the sights. The gun will be more accurate but much slower than firing from the hip.
 * Right stick (while in first person view) - Rotate quickly to spin the gun on your finger.

EZ Gun
This is a tranquilizer gun that you only get if you're playing on Very Easy difficulty. While equipped with this, your stamina usage is reduced to near zero and your camo index goes up to the highest it can go. It also has infinite ammo, a lasersight, and is completely silent.

Controls
 * Square - Hold to bring the gun into view. Release quickly to shoot. Release slowly to lower the weapon without firing. Note: This gun takes a bit of time to rechamber the next round.
 * L1 - While aiming, will zoom the view to 2x for easier aiming.

M37 Shotgun
A very (very) powerful shotgun that will knock enemies very far back when you shoot them with it. Holds 5 shells (4 + 1 chambered), takes a while to rechamber the next round, and takes even longer to reload. You cannot use iron sights on this weapon, so aiming is very tricky. Also, CQC is disabled for this weapon.

Controls
 * Square - Aim and fire.
 * Circle - Strike with the butt of the weapon, knocking guards down.

XM16E1 Assault Rifle
An experimental assault weapon developed by the United States Army. Has three firing modes and can be fitted with a suppressor (though those are rather difficult to find). Holds 21 rounds (20 + 1 chambered).

Controls
 * Square (hold lightly) - Raise and aim the weapon.
 * Square (hold firmly) - Fire the weapon.
 * Square (release slowly) - Lower the weapon without firing.
 * L1 - Aim down the sights, zooming the view and increasing accuracy.
 * Circle (in Weapon menu) - Attach/remove suppressor.
 * Triangle (in Weapon menu) - Toggle firing modes between Semi-Auto, Full-Auto, and 3-Round Burst.

Patriot Assault Pistol
The Boss carries this weapon. It's an XM16E1, but the barrel has been sawn off, the stock removed, and the magazine replaced with a Beta-C magazine shaped like an infinity symbol. It's loud, it's powerful, and it has infinite ammo - but it's bound to arouse the suspicion of nearby guards if you're not careful. Who says that's a bad thing, though?

Controls
 * Square - Hold lightly to bring the gun into view. Press firmly to fire in full-auto.
 * L1 - Aims down the sight, zooming in slightly and increasing accuracy.

Mosin-Nagant Tranquilizer Rifle
The End's sniper rifle. It won't kill enemies - merely drug them. It acts about the same as the SVD, but with a very long lag time after each shot. Make sure you're well hidden when you use this, or else the guards will hear the shot and find you.

Controls
 * Square - Hold to raise and aim the gun. Release quickly to fire a round. Release slowly to lower the gun.
 * L1 - Looks through the scope.
 * Triangle - Switches between 4x and 10x zoom modes while using the scope.
