Nightstick

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

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

It can be found in the following campaigns:
 * The Parish
 * No Mercy
 * Crash Course
 * Death Toll

The Nightstick is classified as a Bludgeoning weapon, and will spew blood, but will never dismantle the Infected.

Pros

 * Has the fastest attack rate of all melee weapons (except for the Chainsaw).
 * Can be randomly dropped by defeated Riot Infected.

Cons

 * Has an incredibly small arc of swing
 * Poor hit registration on Infected
 * Has an odd animation for a swing from this weapon, meaning that it can be hard to tell if you have scored a hit

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.
