Raven Rock is one of the most claustrophobic locations in No More Room in Hell 2. Instead of relying on wide outdoor spaces, the map sends survivors through a sprawling underground military facility filled with locked security doors, maintenance tunnels, stairwells, flooded passages, and industrial machinery.
The biggest challenge isn't simply killing zombies. Knowing which sector you are in and where the next objective leads can save your squad from unnecessary backtracking.
This Raven Rock map guide breaks down the facility's major areas, explains how they connect, and highlights the most important navigation points.

Raven Rock Map Overview
Raven Rock is built around a deep underground military complex.
The facility gradually moves your squad from the surface perimeter into increasingly deeper sections of the bunker.
The main route can be understood as:
Each area has a different purpose.
| Area | Main Function |
|---|---|
| Surface Perimeter | Initial approach and facility entry |
| Motor Pool | Transition from the exterior into the bunker |
| B1 | Main entrance and blast-door checkpoint |
| Sector A | Administration and security access |
| Sector B | Command & Control and lockdown override |
| Sector C | Maintenance tunnels and substation |
| Sector D | Deep silo and transponder objective |
| Cargo Lift | Final extraction |
The important thing to remember is that the route generally moves downward and deeper into the facility before eventually ending at the extraction elevator.

EXTRACTION
This isn't intended to replace an in-game minimap. Instead, it gives you a mental map of Raven Rock's progression.
1. Surface Perimeter & Motor Pool
Your run begins outside Raven Rock.
The surface approach leads toward the facility's outer security perimeter and the Motor Pool Yard.
What to Look For
The exterior section contains:
- Security fencing
- Checkpoint structures
- A perimeter guard house
- The route into the Motor Pool
- The entrance leading toward the underground bunker
The guard house is worth checking before moving deeper into the compound because useful progression items can appear there.
Navigation Tip
Don't spend too long wandering around the exterior. Once your squad has established a route through the perimeter, move toward the main bunker entrance. The Motor Pool essentially serves as the transition between the surface and Raven Rock's underground sections.
2. B1 Main Blast Door
The next major landmark is the B1 Main Blast Door.
This is one of Raven Rock's first major progression blockers.
If the door appears inactive, don't waste time repeatedly trying to force it open. Instead, look for the nearby B1 Transformer Shed / maintenance area. The power system controls access through the blast door.
B1 Navigation Rule
When you reach the sealed blast door: Look for the electrical infrastructure nearby rather than searching for another door.
Once the required power is restored, the route continues into the administrative sections.
Why B1 Matters
B1 is effectively Raven Rock's first underground navigation checkpoint. Once you pass it, the map becomes considerably more enclosed, with:
- Office corridors
- Security doors
- Stairwells
- Control rooms
- Maintenance routes
3. Sector A: Administration
Sector A is the administrative portion of Raven Rock.
Expect a noticeably different environment compared with the industrial areas later in the map.
You'll encounter:
- Office cubicles
- Desks
- Administrative corridors
- Security checkpoints
- Locked access doors
- Interior stairways
The Red Keycard is particularly important in this section.
Finding Your Way Through Sector A
When entering Sector A, use the office corridors as landmarks rather than trying to memorize individual rooms. If you're searching for the keycard, check:
- Office desks
- Security desks
- Cubicles
- Nearby storage areas
Sector A Exit
The important navigation goal is finding the security door that leads toward Sector B. Once the appropriate clearance is used, continue deeper into the facility.
4. Sector B: Command & Control
Sector B changes the environment again.
This area functions as Raven Rock's Command & Control section and contains the terminal required to override the facility lockdown.
Look for:
- Security monitors
- Control consoles
- Emergency lighting
- Elevated command areas
- Large terminal stations
The command room is an important landmark because it represents the transition from the administrative section into the deeper industrial facility.
The Lockdown Terminal
The primary progression interaction here is the facility command terminal.
Select:
Once the lockdown is cleared, the route into the lower maintenance sections becomes accessible.
Navigation Tip
If your squad reaches a locked route deeper into Raven Rock, don't immediately assume you missed a key. Check whether the Sector B lockdown has been overridden first.
5. Sector C: Research & Substation
Sector C is where Raven Rock starts to feel significantly more industrial.
The clean office corridors give way to:
- Maintenance tunnels
- Utility rooms
- Industrial storage areas
- Narrow passages
- Lower service corridors
- Partially flooded sections
- Generator infrastructure
This is one of the most important areas to learn because your squad needs to search it for two Industrial Fuses.
Sector C Navigation
Sector C isn't simply one straight hallway. Expect to move between maintenance rooms and lower utility passages while searching for the required components. The important destination is the Substation / Generator Room.
Think of the area in three parts:
│
├── Maintenance Rooms
│
├── Utility / Flooded Passages
│
▼
SUBSTATION
│
▼
GENERATOR ROOM
Finding the Industrial Fuses
The two required Industrial Fuses can appear in different locations. Search:
- Maintenance rooms
- Storage shelves
- Supply crates
- Lower utility corridors
The Substation
Once both fuses have been recovered, return to the substation panel. Installing the components allows the generator to be activated.
After the generator starts, the facility opens into the next major section: Sector D.
6. Sector D: Silo
Sector D is one of the most distinctive areas of Raven Rock.
Instead of the relatively horizontal corridors found elsewhere, the Silo features a deep vertical structure with spiral walkways and multiple levels.
This makes orientation particularly important.
How to Navigate the Silo
Once you enter Sector D, look for the major spiral walkway. Your destination is:
The objective is not simply to explore the entire Silo. Instead, follow the vertical route downward until you reach the area containing the Heavy Radio Transponder.
Silo Navigation Tips
- Keep your squad together on the spiral walkways.
- Watch for zombies approaching from different elevations.
- Avoid running too far ahead of the group.
- Use landings as temporary regroup points.
- Remember the route you used to descend because you'll need to carry the transponder back out.
The last point is particularly important. The Silo is much easier to navigate on the way down than while carrying the Heavy Radio Transponder back toward extraction.
The Heavy Radio Transponder
The Heavy Radio Transponder is the major objective item in Sector D. Once picked up, it changes how the carrier moves through the facility.
The carrier:
- Cannot sprint
- Cannot use normal firearms
- Moves at a slower walking pace
- Can perform a defensive shove
- Can drop the transponder to regain weapon access
Because of this, the Silo becomes one of the most dangerous areas to traverse while carrying an objective item.
Best Route
Don't split the squad between the Silo and the extraction route. Instead: Carrier in the middle → combat players ahead and behind → move together toward the Cargo Lift.
7. Cargo Lift Platform
The final major landmark is the Cargo/Freight Lift.
This is located deep beneath the facility and serves as Raven Rock's extraction point.
It is important to understand that the Cargo Lift is not simply a doorway you walk through.
Your squad must:
- Bring the Heavy Radio Transponder to the lift.
- Install it into the appropriate console.
- Activate the extraction sequence.
- Defend the platform.
- Survive the full 4-minute countdown.
- Leave together when the elevator extraction completes.
Cargo Lift Layout
Think of the final area as a defensive arena:
│
▼
┌─────────────────┐
│ │
│ CARGO LIFT │
│ PLATFORM │
│ │
└─────────────────┘
▲ ▲
│ │
Ramp / Ramp /
Approach Approach
The exact geometry can make the holdout feel chaotic, but the basic strategy is straightforward: Defend the approaches rather than chasing zombies away from the platform.
Raven Rock Navigation Tips
1. Learn the Major Landmarks
You don't need to memorize every room. Instead, remember:
If you know which sector you're currently in, you're already much less likely to become lost.
2. Use Objective Rooms as Navigation Anchors
Important objectives naturally create useful landmarks.
For example:
- B1: Transformer / blast door
- Sector A: Security access
- Sector B: Command terminal
- Sector C: Substation
- Sector D: Silo / transponder
- Cargo Lift: Extraction
If someone asks, "Where are we supposed to go?", identify the next objective room rather than trying to describe every corridor.
3. Don't Rush Through Unpowered Areas
Raven Rock contains sections where doors and systems aren't immediately usable. If you encounter a seemingly impossible route, look for:
- Breaker panels
- Terminals
- Security doors
- Missing components
- Nearby maintenance rooms
The map frequently uses environmental progression rather than traditional key-and-door design.
4. Treat Sector C as a Search Area
Sector C is one of the easiest places to waste time. Instead of randomly wandering, split the search intelligently. One or two players can check maintenance rooms while another watches the main route. Once both required fuses are located, regroup before returning to the substation.
5. Remember the Route Before Picking Up the Transponder
This is one of the most useful Raven Rock navigation habits. Before picking up the Heavy Radio Transponder, make sure everyone understands where the Cargo Lift is. The carrier cannot sprint or use firearms normally, so getting lost while carrying it can be disastrous.
Best Places to Regroup
Certain areas naturally work better as temporary regroup points.
B1 Entrance
Useful early in the mission before the squad commits to Sector A.
Sector B Command Area
A useful reference point between the administrative and industrial portions of the facility.
Sector C Substation
An important regroup location before activating the generator. Make sure everyone is ready before triggering the noise event.
Sector D Silo Landings
Use the wider sections of the spiral route to regroup while moving toward the transponder.
Cargo Lift Platform
Once extraction begins, this becomes the squad's primary defensive position.
Common Raven Rock Navigation Mistakes
Getting Lost After the Blast Door
Problem: Players enter B1 and start exploring every corridor.
Solution: Follow the progression toward Sector A and look for the security access route.
Searching Sector A Forever
Problem: The squad assumes the Red Keycard has a single guaranteed location.
Solution: Search the surrounding administrative and security areas because item locations can vary.
Confusing Sector B and Sector C
Problem: Players return to the command area after already clearing it.
Solution: Once the lockdown is overridden, your next major destination is the industrial Sector C area.
Losing Track of the Generator Room
Problem: Players collect the fuses but can't remember where they came from.
Solution: Keep the Substation/Generator Room as your central Sector C landmark.
Getting Separated in the Silo
Problem: One player reaches Level -2 while everyone else is still on the spiral walkway.
Solution: Move as a group and use landings to regroup.
Carrying the Transponder Without a Route Plan
Problem: The carrier becomes trapped or surrounded while trying to find the extraction point.
Solution: Identify the Cargo Lift route before picking up the transponder and have armed teammates lead the way.

What is the most important Raven Rock navigation tip?
Don't try to memorize every room. Learn the location of the major objective landmarks and always identify your next sector before moving deeper into the facility.
Final Raven Rock Navigation Tip
Raven Rock looks complicated because of its interconnected corridors and underground rooms, but the main progression is surprisingly easy to understand once you divide the map into sectors.
Keep the squad together, use objective rooms as landmarks, and avoid unnecessary exploration once the next progression route is clear. That approach makes the bunker far less intimidating—and gives your team a much better chance of reaching the Cargo Lift with enough resources to survive the final holdout.
