Dead by Daylight Generator Repair Guide Skill Checks, Efficiency & Strategy

Generators are the Survivor's primary objective in Dead by Daylight. Five must be repaired before exit gates can be powered — and how efficiently your team does this determines whether anyone escapes or the Killer has time to pick everyone off. This guide covers the base repair mechanics, skill check timing, multi-survivor efficiency math, generator regression, dangerous 3-gen clusters, and the best perks to accelerate repairs.

01Generator Basics

Each trial spawns seven generators on the map, and Survivors must repair five of them to power the two exit gates. Hold the action button near a generator to begin repairing — your character will automatically work on it and the generator's progress tracks visually as a percentage meter.

A standard generator requires 90 charges to fully repair, which translates to 90 seconds of continuous solo repair at base speed (no perks or items). Generators make noise while being repaired — a repeating mechanical sound — that can alert the Killer if they're nearby. When a generator completes, a burst of sparks and a loud audio cue announces it to every player on the map, including the Killer.

You can stop repairing at any time by releasing the action button or being interrupted by the Killer. The generator holds its current progress — nothing is lost by interruption alone. If the generator is kicked by the Killer, it begins regressing.

02Skill Checks

While repairing (and while performing other actions like healing), skill checks appear randomly as a circular prompt with a rotating needle and a highlighted zone. Hitting the highlighted zone successfully completes the skill check.

• Good Skill Check: The needle lands in the outer highlighted zone. The repair progresses normally with no bonus or penalty.
• Great Skill Check: The needle lands in a smaller inner zone within the highlighted area. In addition to the normal repair progress, you gain a +1% bonus to generator progress — small but meaningful over many skill checks.
• Failed Skill Check: You miss the zone entirely. The generator loses 10% progress instantly, your repair pauses for 3 seconds, and an audio and visual notification alerts the Killer to your location. Failing a skill check in a risky position (the Killer nearby) is one of the most costly mistakes a Survivor can make.
• Skill check frequency: Skill checks appear at semi-random intervals during repair. Certain perks (Hyperfocus, Stake Out) and add-ons can increase skill check frequency or modify the hit zones.

Training to hit skill checks reliably is a basic skill most players develop naturally. If you're missing them consistently, slow down your focus and watch the needle's rotation speed — the needle does not speed up mid-check, so you can anticipate its arrival in the zone.

03Multi-Survivor Efficiency

Multiple Survivors can repair the same generator simultaneously, which speeds up completion but not as much as you might expect. The game applies a -15% efficiency penalty to each Survivor for each additional person repairing alongside them.

• 1 Survivor: 90 seconds (100% efficiency).
• 2 Survivors: Approximately 53 seconds. Each person repairs at 85% of their base rate, but two people working together still beats one by a significant margin.
• 3 Survivors: Approximately 43 seconds. Each person repairs at 70% base rate.
• 4 Survivors (all on one gen): Approximately 41 seconds. Each person repairs at 55% base rate — this is extremely inefficient compared to spreading out across two generators.

The practical takeaway: two Survivors per generator is the sweet spot in most situations. It's significantly faster than solo repair and far more efficient than packing three or four onto a single gen. Spreading your team across two generators simultaneously is almost always better than clustering everyone on one — unless a generator is nearly complete and just needs one more person to push it over the line.

The perk Prove Thyself (Dwight Fairfield) offsets this penalty by adding up to 10% repair speed per other Survivor within 4 metres (up to 30% at Tier III), and extends the bonus to nearby teammates without the perk. It turns two-person repair into a significant speed advantage.

04Generator Regression

When a Killer presses the action button near an unattended generator, they kick it. Kicking a generator:

• Removes 5% progress instantly (buffed from 2.5% in a prior patch).
• Starts automatic regression at a rate of 0.25 charges per second (roughly 0.25% per second) — slow but continuous.
• Sends a notification to the Killer when the generator's progress level changes significantly.

Survivors must repair a regressing generator for a minimum of +5% progress to stop the regression. If you touch a regressing gen and add less than 5% before stepping away, it resumes regressing once you leave.

Regression is uncapped since a prior patch change — a generator can regress all the way to 0% if left unattended long enough. In practice, generators regress slowly enough that a single Survivor can stop regression and rebuild progress, but a Killer who patrols multiple generators and kicks each one forces Survivors into reactive repair cycles rather than forward progress.

The Killer must physically travel to each generator to kick it. Each generator has a regression event limit of 8 — once a generator has been kicked 8 times, the Entity's spikes block the Killer from interacting with it further (Survivor skill check failures still regress it regardless of the counter). Perks like Pop Goes the Weasel (clown) and Corrupt Intervention add additional regression or blocking mechanics on top of basic kicks.

05The 3-Gen Situation

One of the most dangerous late-game scenarios for Survivors is the 3-gen. This occurs when only three generators remain unrepaired and they are in close proximity to each other — forming a triangle the Killer can defend by patrolling between them.

In a 3-gen situation the Killer can kick each generator in sequence and patrol the cluster. Any generator Survivors try to push will be within range for the Killer to interrupt the chase and kick it again. It is extremely difficult to complete a generator out of a 3-gen cluster without losing a Survivor in the process.

How to avoid a 3-gen:

• Early in the trial, identify which generators are clustered. The perk Deja Vu reveals the three closest generators to each other at trial start and gives you a bonus repair speed on them — this directly helps you break up clusters by completing one of the three early.
• Spread your early-game repair pressure across different areas of the map rather than completing generators in a single quadrant. Completing generators that are far from each other leaves no compact cluster for the Killer to defend.
• If you are already in a 3-gen, consider trying to complete the most isolated generator of the three first to break the cluster, even if it's harder to reach safely.

06Best Generator Perks for Survivors

• Prove Thyself (Dwight Fairfield): Adds 10% repair speed per other Survivor within 4 metres (up to 30% at Tier III), and extends the bonus to nearby teammates without the perk. Makes two-person repair significantly faster and is the most consistent gen perk in solo queue.
• Hyperfocus (Kate Denson): Each Great Skill Check stacks a token (up to 6). Each token adds 4% repair speed and increases the Great Skill Check bonus from +1% to up to +5.4% at max stacks. The acceleration is dramatic — a fully stacked Hyperfocus makes a single Survivor the fastest solo repairer in the game.
• Stake Out (Ace Visconti): Spending time within 32 metres of the Killer while not in a chase earns tokens (up to 4) that convert your next Good Skill Check to a Great Skill Check. Pairs directly with Hyperfocus to continuously stack tokens and maintain high repair speed.
• Deja Vu: Reveals the three generators in the closest cluster at trial start and gives a 6% repair bonus on them. Primarily a map-awareness and anti-3-gen perk, though the repair bonus is a real secondary benefit.
• Toolboxes: Toolboxes are Items (found in chests or brought from the lobby) that boost repair speed while equipped and held. A base Toolbox gives approximately +25% repair speed. The add-on Brand New Part completes a generator instantly when applied — it's a one-use consumable but the most powerful single-gen acceleration item in the game.
