Left 4 Dead Killer Concept: The Horde

The Horde (L4D Licensed Paragraph)

Power: 

Main ability: Hive Mind

6 Special Units are spawned around the trial.

The Smoker, The Boomer, The Spitter, The Witch, The Tank, and The Charger.You will start as one of them at random.

Pressing the Active Ability Button will show you the aura of all units. Pressing the Secondary action button while looking at one arua will move your perspective to that unit and allow you to control them, the one you left becoming inactive. Inactive Units do not lose Collision.

On shift each Unit will make a Noise to signal to the survivors

Using this method you cannot switch again for 60 seconds.

Each unit has different abilities and restrictions.

The Smoker: 

Pressing the Secondary action button will start a charge. When the charge is complete The Smoker will shoot out its tongue. Any survivor hit by the tongue will be restrained and pulled toward The Smoker. Attacking the survivor will release them from the tongue. Hitting a survivor being pulled in will inflict the Deep Wound status effect. If the survivor is in the injured state the attack will down them instead.

The Smoker cannot break pallets and breakable walls

The Smoker will play its Bacteria (Stringed version) when controlled

The Boomer: 

The Boomer is a volatile being, and has been messed with by the Entity to create a fairness in how it plays within the trials. When The Boomer is stunned by a pallet or by a locker it will explode, break the pallet and cover the survivor in Zombie Bile. Bile inflicts the exposed status effect for 80 seconds and reveals the survivor’s location to the killer with Killer Instinct for 80 seconds.

When the Boomer explodes The mind is moved to the last unit it was placed in. And The Boomer will respawn in some time. Changing like this will not allow you to change again for 20 seconds.

The Boomer cannot Vault Windows or Pick up dying survivors due to its large size. The Boomer moves slower than almost all other units.

The Boomer will play its Bacteria (Stringed version) when controlled

The Spitter: 

The Spitter can utilize the Zombie Bile in a ranged way. Pressing the Secondary Action button will have The Spitter fire a glob of Zombie Bile forwards. This glob flies over pallets and small walls and inflicts the exposed status effect for 25 seconds and reveals the survivor’s location with Killer Instinct for 25 seconds. This ability cannot be used again for 30 seconds after being used.

The Spitter cannot break Generators as the sparks ignite the Bile pouring out her mouth.

The Spitter will play its Bacteria (Stringed version) when controlled

The Witch: 

The Witch is a shy creature, and is acutely aware of her surroundings. All Survivors within 10 meters of the witch have their location revealed with Killer Instinct for as long as they are within range. If the Witch sees a survivor with direct line of sight, Pressing the Secondary action button will have her leap forwards and chase the survivor at high speed until they are put into the dying state. If the Leap hits the survivor is instantly put into the dying state. If blinded by any means The Witch will see the auras of any survivors within 16 meters for 8 seconds.

The Witch cannot end chases with Survivors by breaking Pallets or Breakable walls.

The Witch Vaults over Pallets and Windows automatically when in pursuit.

The Witch is blinded easier.

The Witch cannot see Scratch marks

The Witch will play the first 3 seconds of its theme when controlled

The Tank: 

The Tank is the biggest and slowest mass. The Tank cannot be stopped and gets very angry when tested. After being stunned by any means The Tank will flail its arms around itself, breaking any object within reach, and inflicting the Deep Wound status effect on any survivor in reach. After exiting this tantrum state The Tank gains a moderate haste effect and sees the aura of the survivor that stunned it.

The Tank breaks objects faster than other units. 

The Tank is the Slowest Unit in the match. 

The Tank cannot View Auras of Generators.

The Tank will play the first 3 seconds of its theme when controlled

The Charger: 

The Charger has one hulking arm and rushes all living flesh it can see. Pressing the Secondary action button will have The Charger move forward at high speed. Any survivor in The Charger’s way is trampled and placed one health state lower. The Charger does not stop until it hits a wall.

The Charger cannot interact with Lockers as it’s right arm is too large.

The Charger will play its Bacteria  when controlled

Special ability: Activated Mind

Upon the activation of a generator one random Inactive Unit turns into an active unit moving around the trial.

Each Unit can be stunned by using a pallet, locker, flashlight, flash bang or firecracker. 

Each unit has a different ability within this state.

The Smoker: 

The Smoker will move around the map very slowly and aim its tongue at any loud noise notification. It will shoot its tongue out every 50 seconds if it is not controlled. If the tongue hits a survivor they will scream and be pulled towards The Smoker. In this state the tongue will never put a survivor into the dying state and only inflict the Deep Wounds status effect.

The Boomer: 

The Boomer will move around the map very slowly attempting to get close to any pallet or locker. The Boomer, if stunned, explodes, breaks the pallet and covers the survivor in Bile. Bile inflicts the exposed status effect for 40 seconds and reveals the survivor’s location to the killer with Killer Instinct for 40 seconds. 

The Spitter: 

The Spitter will move around the map very slowly attempting to get close to any generator with any amount of completion. If it spots a survivor it will fire one glob of Bile towards them. If this Bile hits the survivor they will scream and become exposed for 15 seconds and have their location revealed by Killer Instinct for 15 seconds.

The Witch: 

The Witch wil sit in place and start wailing. Any survivor within 12 meters of her will have their location revealed by Killer Instinct until they leave this range. Attempting to Flashlight blind her in this state will result in a swift attack injuring any survivor attempting it.

The Tank: 

The Tank will wander the map slowly and chase down any survivor it sees. If it comes across an undamaged generator it will break it. If The Tank attacks towards a survivor but hits another Active Unit aside from The Charger it will stun them for 5 seconds. The Boomer will explode if hit. Stunning The Tank in this state will cause it to enter a tantrum for a short time and then chase the survivor that stunned it at an increased pace.

The Charger: 

The Charger will rush towards the farthest Generator by moving in as few straight lines as possible. Once it reaches that point it will rush towards the next target. Any survivor in its way will be trampled and injured. If The Charger hits an injured survivor in this state they will be inflicted with the Deep Wounds status effect.

Special ability: Endgame Rush

When the exit gates are opened or the hatch is closed all current Units are removed from the Trial and replaced with two separate Units. The Jockey, and The Hunter. You control The Hunter by default. Each unit has separate abilities and are always active. Switching between the two can be done by pressing the Alternate Action Button and can only be done every 20 seconds

When being controlled:

The Hunter: 

The Hunter is an average sized creature only distinguished from humans by the animalistic sounds it makes. You move at high speed around the map. Pressing the Secondary action button will cause The Hunter to Leap forwards. If The Hunter hits a wall with a leap you can press the Secondary action button again in a short time span to jump off the wall in a new direction. Hitting a survivor with this leap will instantly put them in the dying state.

The Hunter vaults Windows and Pallets much faster. 

The Hunter can crouch before leaping increasing the distance it leaps.

The Hunter cannot perform basic attacks.

The Jockey: 

The Jockey is a hunchback beast. Pressing the Secondary action button will make The Jockey jump forwards. If The Jockey hits a Survivor both players lose control of themselves and The Jockey moves the hit survivor away from the nearest door. Both players regain control after 1 second as the Entity intervenes, stunning both players for 3 seconds. If The Jockey hits a wall when jumping it will be stunned for 3 seconds. If the Jockey hits a Pallet or Breakable Wall it will break the object. 

The Jockey cannot vault.

The Jockey’s power will be disabled after landing 4 times.

When not being controlled:

The Hunter: 

The Hunter will leap and bound moving at a fast pace towards the nearest exit gate from where it was. After making it to the exit gate, The Hunter will patrol the 3 nearest Tiles at a moderate pace growling and letting off sound cues if it spots a survivor before dashing towards them. The Hunter will attack and inflict the dying state on survivors that get too close to it. 

The Jockey: 

The Jockey will move around the map at a moderate speed moving towards the closest exit gate to its spawn point. If it spots a survivor it will latch onto them inflicting the incapacitated status effect and reducing their speed. The Jockey can only be removed from the survivor by another Survivor. The Grappled Survivor cannot leave the Trial.

Perks:

Hunger of Many:

If more than 2 injured survivors are within your Terror Radius the Auras of injured survivors within 16/20/24 meters are revealed for 6/7/8 seconds.

Desperate Pursuit:

 This perk starts with 1/2/3 tokens. For each escaped survivor, lose 1 token, and gain 2% haste status effect for the remainder of the trial.

Hex: Corral: 

Once the exit gates are open, one Dull Totem becomes a Hex Totem and Hex: Corral activates 

When a survivor is put into the injured state by any means, gain a token. After gaining 3 tokens the next survivor hit is put into the dying state and you lose all tokens. 

While Hex:Corral is active gain a cool down reduction on missed attacks of 30/40/50 %

For a Closer Look at things like Stats and specifics of the abilities please refer to this Document. I have also included a lot of personal thoughts about the power, Sources for some of the Ideas, and Cut content. Currently I am working on the Stats for each Unit's power while being controlled but have finished most everything that I could.

This killer Received a quick aesthetic rework shortly after I had learned of the Bacteria and Danger themes for each Zombie.

The Horde generally is designed to work as a team of abilities but also be strong enough on their own. Each unit getting a restriction to what actions they can perform emphasizes the teamwork aspect of the killer and will generally force players to interact with at least 3 if not 4 of the Units in any one match. The majority of their powers are rebrands and small edits on the powers of other killers. (Smoker and Deathslinger, Tank and Leatherface, Jockey and Victor, and Charger and Hillbilly) So, YES, I am aware of the redundancy of putting a few of them in the game.

Thank you for your time. All reasonable criticism is accepted.
