Metal Gear Solid 4 is the top-selling Playstation 3 game from Konami, featuring Solid Snake. While the game is about sneaking and stealth, since you're mainly travelling through warzones, you might feel the urge to use one of the 70 available weapons that have made it into the game. Many of these weapons can also be customised, adding scopes, silencers, flashlights, and more onto them. Having so many weapons in the game can get confusing, so it's helpful that you can visit Drebin's shop at any time (once you've met him) to buy new weapons and ammo. I will not be looking at all of the Metal Gear Solid 4 weapons, but just the highlights.
Let's first have a look at the Handguns:
MK. 23 a.k.a SOCOM
Anyone that's played Metal Gear Solid 1 will remember this gun as Snake's primary pistol. Developed for the U.S. Special Operations Command, it has a 45 caliber barrel, and comes with laser aiming and a specially developed suppressor. The gun is one of the best in its class, due to the large magazine capacity compared to its size.
This is my personal favourite pistol, as I like to play a stealth game, and of all the Metal Gear Solid 4 weapons, this fits the bill perfectly. It is completely soundless, as it uses a special type of soundless ammo, eliminating the need for a suppressor. While each magazine can only carry 6 rounds, that is more than enough to take down one or two soldiers at close range, undetected.
The Race Gun
This gun is a bit special, and can only be acquired after completing the game. What is lacks in power, it makes up in the fact that it can fire rapidly. It is also the only gun that can bounce bullets off of walls, ala Revolver Ocelot in the first Metal Gear Solid. Unfortunately there are no modifications possible, but it's still a lot of fun to use.
Next, let's take a look at the Submachine Guns:
The Patriot is the weapon of The Boss in MGS3, and is an exceptional gun. It is the weapon of a master, and requires no reloading at all during combat. When looking at it from the front, the magazine forms the shape of an infinity symbol, which is a nice touch.
The P90 is a specialised weapon that provides you with good mobility during combat, thanks to its shape. Best used at close range, it can take down large crews in seconds thanks to its impressive rate of fire. This can be found all over the first level, as it's carried by the FROG troopers.
It is basically a shortened model of the M16, and is the mainstay of U.S. Special Forces. It includes a highly-revolutionary 'rail system', which makes it compatible with a lots o add-on parts, almost like a 'Do It Yourself' gun. This is probably the gun I used most during my first play-through, as it can be heavily customised, it is useful in nearly every situation. For example, you can fit on it a silencer, a scope, a laser sight, a grenade launcher, a shotgun, two different grips to improve accuracy, and a flashlight.
No we're really talking. The DSR-1 is a no-nonsense, bolt-action sniper rifle. Billed by its manufacturer as "the most sophisticated and technologically advanced tactical precision rifle in the world", it certainly packs a punch. Its integrated bi-pod means it's always ready to go, and despite its extreme loudness, it is always guaranteed to take down your victim, should you land a direct hit.
If you want something a little less brash and subtle, then the Mosin-Nagant is for you. Brandished by 'The End' in MGS3, the Mosin-Nagant is a special sniper rifle, as it uses non-lethal, tranquilizer ammo. While this gun is extremely noisy, if it's used from a distance (which is what it's designed for), you won't have a problem. This is one of the Metal Gear Solid 4 weapons that is essential when trying to complete the game without killing anyone.
The rail gun is acquired after defeating Crying Wolf in act 4 of the game. Of all of the Metal Gear Solid 4 weapons, it might just be the most powerful, when fully charged, and is said to pack the same power as a tank turret! There are no modifications that can be made to this weapon, but realistically, there are none that are needed.
