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.
