Machete

The Machete is a close combat weapon introduced in Left 4 Dead 2.

The Machete appears to be somewhat rare for a melee weapon. Like all other melee weapons, it uses the slot of the Pistol. It has a comparatively quick swing speed that can slice and decapitate common Infected quickly, although it's swing range seems to be a bit smaller than other melee weapons. As a bladed weapon, the more kills you get with it, the more blood you get splashed on your screen and on your weapon.

It can also do heavy damage to Special Infected if not killing them outright, although this isn't recommended, since some Special Infected can attack you before you can kill them or are too far way to do anything with a melee weapon, and the other Special Infected have abilities and effects that make them too dangerous to consider killing with a melee attack.

Trivia

 * The weapon could be a reference to the movie 28 Days Later, in which the main female character Selena wields a machete. It could also be a reference to Jason Voorhees from the Friday The 13th series, who is most commonly seen wielding a machete.
 * On the campaign poster for "Dead Center," Coach is wielding a machete.
 * Even though this is a long, bladed weapon that is more than capable of decapitation, you cannot decapitate a Witch with this weapon; only the Axe and Katana are capable of doing so.
 * Survivors bring their other hand up whilst holding the machete in the same way the Sniper from Team Fortress 2 does with his Kukri.
