Riot

" 'Hey look! Its a Police Offic- OH CRAP' - Some Guy "

Description
The Riot is one of the special infected in Left 4 Survival. It currently costs $55 Coins and can be helpful for Hunters, Tanglers and Chillers. It has a headshot resistance, meaning it cannot get extra damage from headshots, making it useful against guns that deal more damage on headshots.

Ability
The Riot’s main ability is “Charge”, which Riot can charge at high speeds and receives a forcefield making it immune to gunshots until it hits a wall. The ability has a 20 seconds cooldown.

New
The Riot wields a nightstick which can be bought by survivors in the shop. Hence its name, it wears a riot control armor, a meshed armor, a shield and headgear which makes it immune to headshots. Unlike other zombies, it has a gray skin, like Hunter. The Riot’s face is “Angry Zombie”, which is possible to see ingame.

Old
This design was used prior to 5.8.7. It is the same design as it does, but with different headgear and riot control armor with any green skin. It uses your avatar’s face instead of “Angry Zombie”.

Weakness
Although Riot has high amount of health, like any high health zombies, it can easily be overwhelmed by weapons with heavy firepower.

The Riot only charges at straight line, which makes it easy to dodge when it charges from afar.

Survivors

 * Don't shoot or even try to attack a charging Riot, it's a waste of ammo and will probably allow it to hit you if you go in with a melee weapon
 * When they charge they get a forcefield, making them immune to all types of damage
 * Try to take the Riot from longer ranges, if he gets close enough he will rush and hit you
 * DON'T AIM FOR THE HEAD. Riot's helmet is too strong, headshots won't deal extra damage
 * Keep walking to random directions that could decrease the chance of the Riot hitting you with the Rush
 * Try to dodge the charge attack, this allows you to escape the riot zombie quickly and kill him.
 * Riot is immune to knockbacks and stuns, do not use these against this zombie.

Zombies

 * Use your charge to your full advantage, use it to deal decent damage to survivors that are near you or for flanking survivors that are running a certain direction.
 * Don't use your charge to move faster, if you hit something a stun animation will play, leaving you vulnerable for a few seconds. (0.8 estimated)
 * If you think you're going to die you can use the Charge ability to escape and find another survivor, due to the forcefield.
 * You cannot go any directions when charging.
 * If you see a survivor that's pinned by a Hunter or grabbed by a Tangler or freezed by Chiller you should charge at the survivor, it'll remove most of the health.
 * If a survivor is going any direction to prevent you from hitting them, try to aim them by using first person.

Disadvantages (Playing as)

 * You will stop for a second after hitting a wall, meaning you can get killed while stunned.
 * Your riot shield will not stop bullets.
 * Players can easily dodge your charge attack.
 * Loud footsteps while charging.
 * Loud scream while charging, making it easy for players to notice you.
 * Slow charge ability regen.
 * This riot has very garbage hitboxes which can favor the player or you

Advantages (Playing as)

 * Useful if the last player is trying to escape, as it stuns them with the charge attack and lowers their health fast.
 * You can escape using the charge attack. (Keep in mind you cant go in another direction other than forward.)
 * Cannot be killed while using the charge attack.
 * Damages more survivors than one.
 * Infinite charging range.

Trivia

 * The Riot is based on the Charger, a zombie from L4D2 that has a huge arm, allowing it to charge and grab survivors. But it stops charging when it doesn't hit a target or a wall.
 * There's a Riot zombie in L4D2, an uncommon infected that is unable to be shot, meaning you have to shoot the back or attack it with a chainsaw, this might be where the whole riot shield stuff comes from. And they are hired by the CEDA to protect civilians from the infection.
 * In the L4D2 universe, the Riot Zombie drops a nightstick upon death.
 * The Riot is the first zombie to be able to block damage entirely
 * In older versions, the Riot's ability was completely different. The Riot used to be able to block damage using it's shield and did not have a charge move . This old ability was removed and replaced with the charge due to the Riot being underpowered.
 * The Riot uses a Nightstick making it the only zombie to use a weapon, if you don’t count the Juggernaut’s concrete throw attack.
 * The Nightstick can be used by Survivors, making it the first melee to be used by both teams
 * The fact that the Riot zombie knows how to use the shield either shows that zombies can still remember certain things from their past lives if it can help them survive, or that zombies are learning to use certain things to their advantage.
 * Although the shield is in front of the zombie, the zombie is protected on all sides.
 * Even though the riot is wearing lots of armor, it got infected anyways .Either the zombie put the armor on after being infected, further reinforcing the theory about zombies becoming smart, or the zombie disease has evolved to be transmitted by more things like water and air.
 * A riot shield is meant to only protect against smaller weapons like knives and clubs and cant stop bullets. Stopping bullets is a ballistic shield's job.
 * Even though the helmet literally protects you against blunt weapons, you resist against extra headshot damage.
 * In 5.8.7, Riot get some changes:
 * Its health increased from 250 to 325.
 * Charging cool down increased from 15 to 20.
 * Charging doesn't make loud footsteps anymore.
 * However it was returned as it counts as a bug.
 * Riot has an remodel, with having a meshed armor, has its helmet changed and has a Gray skin instead of any green colour.
 * There is a glitch around Winter Holiday 2021, where Riot could get attracted to a pipebomb when it is charging. It cannot be killed due to the forcefield.
