Generators

		These strange machines can be found across this abandoned world. They seem to be some kind of generators, fuelling lights. At first I paid no attention to them, but as days turned into months I employed all of my engineering skills to actually fix one. It attracted one of these beings that is after me. But I also noticed that they were somehow tied to something else.
		~ Benedict Baker, Benedict Baker's Journal

		In my explorations, I found that these strange machines were the key to my survival. The more light they produced, the closer I became to my freedom.

Generators are an interact-able Prop and the main Objectives of Survivors in Dead by Daylight .

Overview

Each Map features several Generators randomly located throughout it.

The Trial Grounds spawn with 7 Generators, 5 of which need to be repaired in order to power the Exit Gates , allowing them to escape from the Trial.

Generator Models

Generator with yellow accents

Outside of some special-event-only models, Generators have 2 distinct variations:

A Generator with red accent colours.
- This type has tall floodlights attached one side of it.
  This Generator type is generally located either outside or inside rooms with tall ceilings.
- The floodlights randomly flicker and blink when the Generator is unrepaired and light up once repairs are completed.
A Generator with yellow accent colours.
- This type does not have any visible attachments and is used in locations that disallows for the attachment of the floodlights due to a limited ceiling height.
  This Generator type is generally located inside rooms.
- Nearby light fixtures flicker and blink when the Geneartor is unrepaired and light up once repairs are completed.

Generator Repair

Side article: Repair Time Calculation

As the Generators have four sides, it is possible for up to four Survivors to repair it simultaneously - assuming that there are no other Props blocking any of the sides. The more Survivors work on the same Generator at the same time, the faster it will be repaired.

If a Survivor stops repairing a Generator, its current progression will be saved. Fully repairing a Generator without the help of a Toolbox, Perks and other Survivors takes 80 seconds, assuming that no Great Skill Checks are succeeded and no Skill Checks are failed.

The Generator Repair time can be reduced by using certain Perks or repairing with a Toolbox . Once fully repaired, the lights attached to the Generator will activate and illuminate the immediate area around the Generator, this will also alert the Killer , who receives an auditory and visual cue of the completed Generator's location.

Killers can grab a Survivor off of a Generator mid-repair (also known as interrupting) and hoist them directly onto their shoulder.

Finding Generators

Generators are part of the Killer's default Aura-reading abilities, meaning that Killer's will see the Aura of any unrepaired Generator present on the Trial Ground.

Survivors do not possess this ability (with the exception of within a limited distance when using the Perk Visionary ) and must find unrepaired Generators using other means.
Generators with red accent colours are easily located by watching out for their blinking and flickering floodlights which tower above the surrounding terrain and props.
If those lights are constantly illuminated, it indicates that the Generator is completed and can no longer be interacted with.

Generators with yellow accent colours are more difficult to locate as their location's limited ceiling height do not allow for attached floodlights. Instead, these Generators are linked to nearby light fixtures (i.e. the lamps in Lampkin Lane houses) or signages (i.e. way-point signs in Treatment Theatre) with the same behaviour as the floodlights.

Efficiency Penalty

When 2 or more Survivors repair the same Generator, the Game incurs a stack-able 15 % Efficiency penalty per repairing Survivor to their individual Repair speed.
This Efficiency penalty can be mitigated by using Prove Thyself .

Repairing Survivors	Efficiency Penalty	Individual Repair Speed efficiency	Combined Repair Speed efficiency	Time to complete a Generator
1 Survivor	0 %	100 % = 1 c/s	1 c/s (1 x 1 c/s)	80 seconds
2 Survivors	-15 %	85 % = 0.85 c/s	1.7 c/s (2 x 0.85 c/s)	~47.06 seconds
3 Survivors	-30 %	70 % = 0.7 c/s	2.1 c/s (3 x 0.7 c/s)	~38.1 seconds
4 Survivors	-45 %	55 % = 0.55 c/s	2.2 c/s (4 x 0.55 c/s)	~36.36 seconds

Skill Checks

Main Article: Skill Checks

Like all skilful interactions, Generator Repair may trigger a Skill Check at any given moment. If a Survivor succeeds a Great Skill Check, the repair progress will receive a 1 % bonus. If they fail a Skill Check, the Generator will explode and lose 10 % of the maximum Repair progress. In addition, during 3 seconds, no further progression will register. The failing Survivor will shy away from the exploding Generator and shield their face. A failed Skill Check will also give the Killer a Loud Noise notification, showing them the Generator's location. Stopping the Repair action at any moment during a Skill Check, will automatically fail it.

Damaging Generators

The Killer has the ability to directly interact with a Generator by walking up to any Generator with some progression, that is not yet fully repaired, and damaging it, causing it to slowly lose progression.
The action is performed akin to breaking a Pallet and takes 2 seconds.
A damaged Generator will start to slowly regress until either a Survivor resumes repairing it or it regresses all the way.

Generators regress at a default rate of 0.25 c/s, taking a maximum of ~320 seconds to regress from 99.9... to 0 %.

A damaged Generator will also continuously emit reddish-white sparks.

Generator Terminology

With Patch 4.3.0, the Developers standardised the terminology used in regards to the various states a Generator may find itself in:

A Generator losing progression over time is referred to as "regressing".
The action of putting a Generator into the Regressing State is referred to as "damaging the Generator".
The action of a Generator losing some progression immediately is referred to as "losing progress".
The action of preventing any interaction with the Generator by the Killer or the Survivor is referred to as "blocking the Generator".
A blocked Generator cannot change its progress.
- A regressing Generator that becomes blocked will remain in the Regressing State, but not lose any progress until it becomes unblocked.
A regressing Generator can lose progress from other Unlockables.

Special Generators

Lunar Generators

The Lunar Generator was a special Generator model that was featured during the Howling Grounds Event.
For every burnt Red Envelope , a Lunar Generator would spawn on the Map.
Repairing the Generator would grant all Survivors a Gold Coin , 80 of which would unlock the Untamed Donkey Jacket customization option for David King.

Frozen Cocktail Machine

The Frozen Cocktail Machine was a special Generator model that was featured during the Scorching Summer BBQ Event.
By default 2 and for every burnt BBQ Invitation , a Frozen Cocktail Machine would spawn on the Map.
Repairing the Generator would grant all Survivors a Frozen Cocktail , 90 of which would unlock the Free Song Bird Slip Dress Customisation option for Kate Denson.

Blighted Generators

The Blighted Generator (formerly Cankerous Generator) is a special Generator model featured during the yearly Blights.
By default 1 and for every burnt Pustula Petals , a Blighted Generator will spawn on the Map.
Repairing the Generator will grant all Survivors who burnt the Pustula Petals bonus Bloodpoints.

Custom Game Mode

Since in Custom Games, it is not necessary to have four Survivors per Trial, the amount of Generators spawning throughout the Map is adjusted to be three more than the number of Survivors starting the Trial.
Additionally, for every Survivor fewer than the default four, the Game will remove one Generator from the required amount to power the Exit Gates.

Start of Trial	Generators on Map	Generators to be repaired
4 Survivors	7 Generators	5 Generators
3 Survivors	6 Generators	4 Generators
2 Survivors	5 Generators	3 Generators
1 Survivor	4 Generators	2 Generators

History

Old Efficiency Penalty

Up to Patch 3.7.0, the Game applied a stack-able 10 % Efficiency penalty to repairs conducted by multiple Survivors:

Repairing Survivors	Individual Efficiency	Combined Efficiency	Time to repair a Generator
1 Survivor	1.0 c/s \| 100 %	1.0 c/s	80 seconds
2 Survivors	0.9 c/s \| 90 %	1.8 c/s	~44.44 seconds
3 Survivors	0.8 c/s \| 80 %	2.4 c/s	~33.33 seconds
4 Survivors	0.7 c/s \| 70 %	2.8 c/s	~28.57 seconds

Change Log

Patch 1.4.0

Added the Damage Generator interaction for Killers.
- After performing this interaction, a Generator slowly regresses by a maximum of 25 % over a maximum of 70 seconds.
  - This equals a regress rate of -0.286 Charges per second.

Patch 1.5.0

Increased the required amount of Charges to fully repair a Generator from formerly 70 Charges to 80 Charges.

Patch 1.8.0a

Increased the maximum Generator regression of the Damage Generator interaction to 100 %.
- The regress rate of -0.286 c/s remained the same.
Reduced the time for the Damage Generator interaction from formerly 3 seconds to 2 seconds.

Patch 2.5.0

Generator Repair by multiple Survivors will now correctly show the Efficiency Penalty by turning the progress bar Red.

Patch 3.7.0

Increased the Efficiency Penalty from 10 % to 15 % per Survivor.
Reduced the Progression bonus from succeeding Great Skill Checks from 2 % to 1 %.

Patch 4.2.0

Updated the Generator model and animations as part of the The Realm Beyond - Part One update.

Trivia

The progress bar's colour is individual to each Survivor's personal Repair speed.
- This means that in case of two Survivors repairing a Generator, but one does so with a Toolbox, the Toolbox Survivor will have a yellow progress bar and the one without will have a red progress bar.
Generators inside larger landmark buildings (or the houses on Lampkin Lane and Badham Preschool) are generally yellow instead of red and do not have lights attached to them, but power the respective building's lights instead.
- The same is true for Generators located on the lower floor of The Game.
Powering the Generator on the Paddle Steamer on Pale Rose will sound its fog horn, that can be heard across the entire map.
Powering the Generator inside Gas Station on Gas Heaven will open the garage door.
- This opens up a new escape route for the Survivors.
Powering the Generator in the Operation Theatre on Treatment Theatre will open all the shutter blinds on the Upper Floor.
- This opens up new escape routes for the Survivors.
Powering the Generator inside the Pantry and the Rotten Shack on Grim Pantry will open the floodgates on the outside of the respective building.
- This grants easier and more direct access to the Lower Floors.
Every Generator on The Game will open a nearby door when powered, creating additional routes.
Powering the Generator inside the temple on The Temple of Purgation will open a doorway as well as close one.
