Nightstick

"♪ Gonna beat me a zombie to death with a nightstick~♪"

- Ellis The Nightstick is a close combat weapon in Left 4 Dead 2 that can be found lying around maps or dropped by Riot Infected upon death.

It can be found in the following campaigns:
 * The Parish (Only time it appears in L4D2 Campaign)
 * No Mercy
 * Crash Course
 * Death Toll

The Nightstick is classified as a Bludgeoning weapon: it will spew blood, but will never dismember the Infected.

Pros

 * Has the fastest attack rate of all melee weapons (except for the Chainsaw), and unlike Chainsaw, you could use it infinitely.
 * Can be randomly dropped by defeated Riot Infected

Cons

 * Has an incredibly small arc of swing
 * Has poor hit registration, meaning that you may have a hard time hitting enemies with it
 * Has an odd animation for a swing from this weapon, meaning that it can be hard to tell if you have scored a hit
 * Not recommended for killing Boomers due to bile showering attacker and any nearby Survivors

Console Command
There is only one console command for the Nightstick:
 * (where XX is a floating point variable)

The variable above will determine the probability for the Nightstick to be dropped by Riot Infected when killed. The value is a floating point number, meaning it can be a number with a decimal. This specific command restricts it to any number between 0 and 1 inclusive. The default is 0.1, therefore all Riot Infected would have a 10% chance of dropping a Nightstick on death, thus, setting it to 1 will guarantee a Nightstick to drop every time a Riot Infected is killed.
