Reload

Reloading (default "R" on computer and "B" on the Xbox360) is the action of exchanging an empty, or near-empty clip on a gun with a new, full clip. However, this is only in real life. As with most shooters, reloading guns in Left 4 Dead stacks the ammo you have in your reserve into the clip you already have until the clip has full capacity. Ammunition is the amount of bullets/shots you have to fire the gun. A single unit of ammunition is called "ammo." The item used to hold ammo is called a "clip." When you reload, your character will yell, "Reloading!"

Shotguns have the slowest reload time, as each individual bullet must be reloaded, so make reloading the shotgun a habit. Sub machine guns have the fastest reload time, compared to capacity of the clip, and reloading doesn't need to be very necessary. Ironically, sometimes it is best to not reload a sub machine gun until you eventually run out, letting your teammates take care of targets while you save precious ammo, and also making a habit of conserving as much ammo as possible.

Pistols have relatively the same reload time as a sub machine gun, but a smaller clip. However, a second pistol can be found to double the clip size, but also the reload time.

Remember to always reload before a Finale or when an oncoming Tank is drawing near. A few tactics while reloading in the heat of battle is to run away when you are almost out of ammo, while using your Melee attack and reloading; proceeding to open fire once reloaded. Listen closely when a teammate yells, "Reloading" and offer cover fire, especially if they are using shotguns.

Obviously, Medkits, Pain pills, and throwing weapons do not have an option to reload.
