International Weapons

Due to the censorship of the German version of the game, Valve decided to port some weapons from Counter-Strike: Source into the game for German players to make up for the censorship. Though this is generally for those who own the German version of the game, anyone who plays with someone who owns the German version will encounter these weapons as well. Some modified servers too have these weapons available.

Combat Knife
"Grabbin' a bread slicer."

- Ellis

The Combat Knife is a slashing weapon, similar to the Katana or the Machete, but with a higher speed, around the same as the Tonfa (Nightstick). The biggest disadvantage is the combination of the speed and slashing, which can cause the screen to get covered with blood almost completely. Just like the Baseball Bat or the Chainsaw, this weapon is able to spawn in every campaign so far, though it's rare and not very common to find more than two in the whole campaign.

H&K MP5
The H&K MP5 is a submachine gun variant weapon, able to spawn anywhere in the campaign - including the safe rooms at the beginning of a campaign. It has a lower rate of fire than the normal SMGs in the game, but to balance this, the H&K MP5 has a slightly higher accuracy than the Submachine Gun while it's damage is the same as the Silenced Submachine Gun.

SIG SG552
The SIG SG552 is a fully automatic assault rifle, very similar to the Assault Rifle, but with a slower rate of fire. It also has a 2x scope, which allows the rifle to zoom in, much like a Hunting Rifle or a Sniper Rifle, but not nearly as far as either weapon, which significantly improves accuracy. The damage per shot is the same as the Assault Rifle, but it fires two more shots per minute. However, reload time is higher than the Assault Rifle, but it is still faster than the Combat Rifle.

Steyr Scout
The Steyr Scout is a bolt-action sniper rifle, but in Left 4 Dead 2, the next shot can be fired before the breech is closed. The magazine capacity, accuracy and damage are very similar to the Hunting Rifle, but the rate of fire is significantly lower and the player can carry 30 more rounds in reserve. In combination with a Laser Sight, this weapon has extremely high accuracy even while the Survivor is running with it. Despite this, it is supposedly better to choose a Sniper Rifle or Hunting Rifle as they do the same damage per shot and have a much higher rate of fire.

Accuracy International AWSM
The Accuracy International AWSM is a bolt-action Sniper Rifle but unlike the other international weapons, there is no standard weapon that it matches functionally. It inflicts a high amount of damage per shot; only the Shotguns deal more per shot.

However, it has the slowest rate of fire (excluding the Grenade Launcher) in the game and low average accuracy while moving, making it relatively ineffective against a Horde, but it is useful for killing the weaker Special Infected from afar with one or two shots. Using it against the Witch or the Tank is not recommended due to its low rate of fire. The higher damage than the Scout actually makes it slightly better in terms of damage per second.
