Dbd-journal-generator.png 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.

IconHelp note.png 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.

The Generators are the main Objectives of Survivors IconHelpLoading survivor.png in Dead by Daylight IconHelp DBDlogo.png.


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 IconHelp exitGates.png, allowing them to escape from the Trial.

Generator Repair

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.

The Generator repair time can be reduced even further by using certain Perks IconHelp perks.png or equipping a Toolbox IconItems toolbox.png. Once fully repaired, the lights above the Generator will activate and illuminate the immediate area around the Generator, this will also alert the Killer IconHelpLoading killer.png, who receives an auditory and visual cue of the Generator's location.

Killers can grab a Survivor off of a Generator if the Survivor is in mid-repair and directly host them onto their shoulder.

Efficiency Penalty

If multiple Survivors repair the same Generator, a penalty to the Repair Efficiency is applied to all repairing Survivors, the penalty increasing with the amount of Survivors partaking in the repair. The initial penalty of two Survivors can be negated by using the Perk Prove Thyself IconPerks proveThyself.png, however it will not completely negate a three or four Survivor penalty, but close enough.

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

Skill Checks

Like all skillful interactions, Generator Repair may trigger a Skill Check IconHelp skillChecks.png at any given moment. If a Survivor succeeds a Great Skill Check, the repair progress will receive a 2 % bonus. If they fail a Skill Check, the Generator will explode and lose 10 % repair progress. In addition, during 3 seconds, no further progress 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 an auditory and visual cue of the Generator's location. Stopping the Repair action at any moment during a Skill Check, will automatically fail it.

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 none failed.

Generator Damage

The Killer can damage an unfinished Generator, if it has some progress on it. Doing this will regress the current progression by a maximum of 100 % over a duration of 320 seconds or at a rate of 0.25 Charges per second. If a Survivor resumes work, the regression will stop. A regressing Generator will constantly emit sparks.

Kill Your Friends Mode

The number of Generators on a Map will always be equal to the number of Survivors starting the Trial +3. For every Survivor fewer than the default four, the Game will remove a Generator, which also lowers the number of Generators needed to be repaired in order 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
