No More Room in Hell 2 Power Plant Walkthrough: Security Overrides, West Gate, Ash Farm & Extraction
Updated: August 2026 — Armageddon Update 1.0
Security Overrides → Lookout Tower / Sawmill / Radio Station → West Gate → Cooling Tower → Ash Farm → Stacker Reclaimer → Extraction
The Power Plant can become difficult when the squad starts splitting up during the electrical repairs. The safest approach is to keep one player on the objective while the rest of the team protects the interaction area, especially on Nightmare difficulty.
The Power Plant is one of the more demanding Objective Mode maps in No More Room in Hell 2. The mission begins outside the main facility, sends your squad through several security-related objectives, and eventually opens the way into the plant itself.
The most important thing to understand is that the opening section is about Security Overrides, while the second half focuses on restoring the plant's major systems.
Once the Cooling Tower, Ash Farm and Stacker Reclaimer objectives are complete, the mission moves directly into the final extraction sequence.

Quick Answer: Power Plant Objective Order
If you just want the route, follow this sequence:
- Start at the Power Plant exterior.
- Follow the objective markers for the required Security Overrides.
- Work through locations such as the Lookout Tower, Sawmill and Radio Station.
- Complete the required electrical and security interactions.
- Return to the main facility perimeter.
- Open the West Gate.
- Enter the main Power Plant complex.
- Restore the Cooling Tower.
- Repair the Ash Farm.
- Restore the Stacker Reclaimer.
- Move to the extraction area.
- Defend the helicopter landing zone.
- Board the helicopter to complete the mission.
Don't let the player performing an objective defend themselves. When someone is repairing wiring, activating a breaker or interacting with machinery, have the other squad members protect them. On Nightmare difficulty, this simple division of roles can make the difference between completing an objective and losing the entire run.
How the Power Plant Mission Works
The Power Plant is divided into two major sections.
Exterior security phase
The opening section takes place around the outer areas of the facility. Your squad must complete the required Security Overrides before gaining access to the main Power Plant through the West Gate.
This portion can take you through several smaller locations, including:
- Lookout Tower
- Sawmill
- Radio Station
These locations also provide opportunities to find weapons, ammunition, medical supplies and other useful equipment.
Main facility phase
After opening the West Gate, the mission changes from security access to infrastructure restoration.
You must repair three major systems:
- Cooling Tower
- Ash Farm
- Stacker Reclaimer
Completing all three triggers the final extraction sequence.
Step 1: Complete the Security Overrides
The first major objective is to clear the Power Plant's security lockdown.
Follow the objective marker rather than trying to memorize a single route through the entire exterior area.
The required interactions involve restoring electrical systems and accessing security equipment.
Depending on where the objective marker sends your squad, you may need to:
- Start a generator.
- Restore electrical connections.
- Complete a wiring interaction.
- Activate breakers.
- Access a security terminal.
- Defend the player performing the interaction.
Don't split the squad too early
The exterior area can look deceptively safe. Once a player begins interacting with a generator, wiring panel or security device, they are vulnerable to attacks.
A better formation is:
The interactor should concentrate entirely on completing the objective. The other players should watch entrances, kill approaching Runners, protect the interactor, keep Walkers away from the interaction point, and watch the team's retreat route.
This is particularly important on Nightmare.
Lookout Tower Security Objective
The Lookout Tower is one of the important exterior locations encountered during the Security Override phase.
The area provides high ground and can also contain useful supplies, but the surrounding infected can make the objective interaction difficult.
What to do
- Approach the Lookout Tower.
- Clear the immediate area.
- Locate the generator.
- Restore power.
- Continue to the electrical interaction.
- Complete the wiring sequence.
- Keep the area protected until the objective registers as complete.
- Follow the next objective marker.
Best strategy
Don't send one player up the tower alone. The interaction leaves the player occupied for several seconds, giving Runners an opportunity to close the distance. Have another player watch the stairs while the remaining squad members cover the surrounding area.
Sawmill Security Objective
The Sawmill is another important exterior location during the Security Override phase.
The lumber yards provide plenty of obstacles and cover, but they can also make it difficult to see infected approaching from different directions.
What to do
- Enter the Sawmill area.
- Locate the electrical panel.
- Complete the wiring interaction.
- Activate the required breaker.
- Confirm that the security objective has progressed.
- Move toward the next objective marker.
Watch the surrounding buildings
Don't focus entirely on the electrical panel. Infected can approach from lumber stacks, side buildings, open yards, and nearby paths. The player interacting with the panel should have dedicated protection.
Recommended squad formation
- Interactor: Handles the wiring.
- Player 2: Watches the closest entrance.
- Player 3: Watches the open yard.
- Player 4: Covers the rear and looks for Runners.
This prevents the squad from being surrounded while the interaction is underway.
Radio Station Security Objective
The Radio Station can cause confusion if you're following older Power Plant information.
For the current Power Plant progression, do not waste time looking for a radio-frequency tuning puzzle here. The Radio Station functions as part of the electrical and security progression.
What to do
- Reach the Radio Station.
- Search the area for supplies if necessary.
- Restore the required electrical system.
- Complete the associated breaker/security interaction.
- Confirm the objective has advanced.
- Continue following the objective marker.
No. The Radio Station should not be treated as a separate frequency-matching puzzle. If you're looking for a radio tuning mechanic because you remember one from another map or an older guide, you're likely looking in the wrong place. The useful rule is simple: Follow the active Power Plant objective marker instead of searching for a radio frequency code.
Step 2: Open the West Gate
Once the required Security Overrides are complete, the mission progresses toward the West Gate.
The West Gate is the entrance into the main Power Plant facility.
How to open it
- Reach the West Gate.
- Approach the gate control point.
- Interact with the control panel.
- Wait for the gate to open.
- Move through the entrance.
- Follow the new objective into the main facility.
The gate is an important transition point between the exterior security section and the Power Plant's internal repair objectives.
Don't bunch up at the gate
The gate area can become a dangerous choke point. Avoid having the entire squad stand directly in front of the entrance while waiting for the interaction.
Instead:
- Keep one player near the control point.
- Spread the remaining players around the approach.
- Watch for Runners.
- Keep a retreat path open.
Once the gate opens, move through as a group.
Step 3: Restore the Power Plant Systems
After entering the main facility, the objective changes.
Your squad now needs to restore three major systems:
- Cooling Tower
- Ash Farm
- Stacker Reclaimer
Each location involves an interaction that can leave the player vulnerable. This is where squad coordination becomes especially important.
Cooling Tower
The Cooling Tower is one of the first major infrastructure repair objectives inside the Power Plant.
How to complete it
- Follow the objective marker toward the Cooling Tower.
- Clear infected around the installation.
- Locate the electrical control point.
- Start the repair interaction.
- Protect the player completing the interaction.
- Finish the system reset.
- Confirm the objective has advanced.
Cooling Tower combat tip
The surrounding structures can create narrow approaches. Don't allow Runners to reach the player working on the machinery.
The ideal setup is: One player repairs while three players control the approaches.
If the area becomes overwhelmed, don't stubbornly remain beside the machinery. Move to a defensible position, clear the immediate threat and then return to the objective.
Ash Farm
The next major system is the Ash Farm.
How to complete the Ash Farm objective
- Follow the objective marker to Ash Farm.
- Locate the relevant control system.
- Clear infected around the interaction area.
- Start the repair sequence.
- Have the rest of the squad protect the interactor.
- Complete the system restart.
- Move on once the objective updates.
Don't rush the interaction
Ash Farm is part of the final group of major Power Plant repairs. Your squad should use this opportunity to reload, heal wounded players, check ammunition, replace weak weapons if better equipment is available, and prepare for the final extraction. Don't burn through every resource simply to clear ordinary Walkers.
Stacker Reclaimer
The Stacker Reclaimer is the third major infrastructure objective. It is one of the final required repairs before extraction.
How to complete it
- Follow the objective marker toward the Stacker Reclaimer.
- Clear the surrounding area.
- Locate the machinery controls.
- Start the repair/calibration interaction.
- Protect the player operating the machinery.
- Complete the sequence.
- Prepare for extraction as soon as the objective finishes.
Protect the objective player
The Stacker Reclaimer area can leave the squad vulnerable if everyone focuses on the machinery.
Assign specific defensive roles:
- Player 1: Objective interaction
- Player 2: Front approach
- Player 3: Side/rear approach
- Player 4: Runner and emergency response
This keeps the squad from being caught off guard.
Best Strategy for Repair Objectives
The most reliable approach to the Power Plant's repair objectives is simple:
When an objective requires a player to stand at a panel or machine, don't have everyone crowd around the interaction.
Instead:
- The interactor focuses entirely on wiring, breakers, switches, machine controls, and repair sequences.
- The defenders focus on Runners, heavy infected, approaching groups, blind spots, and escape routes.
This makes every repair significantly safer.
Prioritize Runners
Runners should be your highest priority during objective interactions. A Walker approaching from a distance is usually less dangerous than a Runner already closing on the player repairing a machine. When a Runner appears: Stop it before it reaches the interactor. Don't allow the player performing the repair to cancel the interaction because the rest of the squad was focused on distant enemies.
Use melee weapons wisely
The Power Plant can consume a lot of ammunition. Use melee weapons against isolated Walkers when the situation is safe.
Save ammunition for:
- Runners
- Heavy infected
- Large groups
- Emergency breaches
- Extraction
A Fire Axe or Shovel can be extremely valuable for conserving ammunition during the earlier objectives.
Power Plant Nightmare Tips
The Power Plant becomes considerably less forgiving on Nightmare difficulty.
The biggest problem isn't necessarily one particular objective. It's the combination of:
- High enemy pressure
- Limited ammunition
- Vulnerable interactions
- Multiple objectives
- Long movement between locations
- Final extraction pressure
Keep the squad together
Splitting into two groups might seem faster, but it also means fewer players are available to protect an objective interaction. Unless the situation specifically requires separation, stay together.
Don't waste ammunition on every Walker
Ordinary Walkers don't always justify spending precious ammunition. If one is isolated and the area is safe, melee attacks can save bullets for the later holdout. But don't become overly committed to melee fighting. If a group is closing in, use firearms before the situation turns into a swarm.
Heal before the final repair
Once you're approaching the last Power Plant objective, check the squad's condition. You don't want to complete the Stacker Reclaimer only to discover that half the team is badly wounded before extraction. Use available medical supplies before the final push.
Keep an extraction reserve
Try to keep some ammunition and healing resources for the final helicopter sequence. The mission isn't over when the final machine is repaired. Extraction is another combat encounter.
Step 4: Survive the Extraction
After all three major Power Plant systems are restored, the mission moves toward extraction.
The squad must reach the designated landing area and survive until the helicopter arrives.
What to do
- Complete the final infrastructure repair.
- Regroup immediately.
- Reload weapons.
- Move toward the extraction area.
- Establish defensive positions.
- Watch the surrounding approaches.
- Survive until the helicopter lands.
- Board the helicopter.
- Make sure the rest of the squad gets aboard.
Don't scatter during extraction
This is one of the worst times to split up. A player who runs ahead can easily become isolated from the rest of the team. Stay together and move as a group. If one player is wounded or downed, prioritize the squad member rather than blindly sprinting toward the helicopter.
Establish a defensive perimeter
Don't have all four players stand directly beside the helicopter. Instead, spread out enough to cover the approaches while maintaining the ability to retreat toward the extraction point.
Watch for:
- Runners
- Large groups
- Flanking infected
- Players becoming isolated
The goal is not to clear the entire area. The goal is to survive until the helicopter is ready.
Common Power Plant Mistakes
1. Trying to solo the wiring objectives
The interaction leaves you vulnerable.
Fix: Have another squad member protect the interactor.
2. Searching for a radio-frequency puzzle
The Power Plant Radio Station is part of the electrical/security progression.
Fix: Follow the active objective and complete the electrical interactions.
3. Calling the location "Asharm"
The correct name is Ash Farm.
4. Using all ammunition before entering the main facility
The later repair objectives and extraction still require resources.
Fix: Use melee weapons against manageable Walkers and save ammunition for priority threats.
5. Standing directly on top of the objective
Four players clustered around one machine can actually make the defense worse.
Fix: Establish a perimeter around the interaction point.
6. Ignoring Runners
Runners can reach an objective player quickly.
Fix: Assign one player specifically to watch for fast infected.
7. Treating the final repair as the end of the mission
Completing the Stacker Reclaimer does not mean you're finished.
Fix: Immediately prepare for the extraction holdout.
8. Running to extraction alone
A fast player can easily become isolated.
Fix: Move toward the LZ together.

Power Plant FAQ
What is the Power Plant objective order in No More Room in Hell 2?
The main route is: Security Overrides → West Gate → Cooling Tower → Ash Farm → Stacker Reclaimer → Extraction. The Security Override phase can take the squad through locations such as the Lookout Tower, Sawmill and Radio Station.
What are the three Power Plant repair objectives?
The three major systems you need to restore are: Cooling Tower, Ash Farm, and Stacker Reclaimer. Complete all three to advance to extraction.
Is it Asharm or Ash Farm?
It is Ash Farm. Use "Ash Farm" when referring to the Power Plant objective.
Does the Power Plant Radio Station have a radio tuning puzzle?
No. The Radio Station is part of the Power Plant's electrical/security progression. You should not waste time searching for a frequency-matching puzzle there.
How do I open the Power Plant West Gate?
Complete the required Security Overrides first, then reach the West Gate and interact with the gate control. Once the gate opens, move into the main Power Plant facility.
What should I do during the Power Plant repair objectives?
The safest strategy is to have one player perform the interaction while the rest of the squad protects them. Prioritize Runners and other dangerous infected approaching the objective.
What should I save for Power Plant extraction?
Try to retain ammunition, medical supplies, strong firearms, and useful melee weapons. The final extraction can become a difficult holdout, especially on Nightmare.
Is the Power Plant difficult on Nightmare?
Yes. The combination of enemy pressure, limited resources and vulnerable objective interactions makes squad coordination particularly important. The best approach is to stay together, conserve ammunition and protect the player performing each repair.
Final Tips
The Power Plant becomes much easier once you stop treating every objective as something one player needs to solve alone.
The winning formula is:
Remember the key locations:
And remember the most important terminology: Ash Farm, not "Asharm."
Most importantly, don't spend all your ammunition before extraction. The final helicopter holdout is part of the mission, so a squad that reaches the LZ with enough resources and stays together has a much better chance of getting everyone out alive.
