Updated September 9, 2026
Space City's extraction system has changed in Delta Force Season 11: Reorientation.
There are now three active Switch Points per match. Two are fixed at Test Range and Centrifuge Facility, while the third randomly appears at Black Chamber or Buoyancy Lab after 15 minutes.
You only need to activate two of the three active Switch Points to enable the Helicopter Extraction.
Season 11 also adds a new Central Garden one-way executive elevator, giving players with the appropriate Desmoulins access another route toward the upper area.
If you're returning from Season 10, the easiest way to remember the new extraction system is:
4 possible Switch locations → 3 active per match → 2 required for helicopter extraction.
This guide covers the new Switch Point locations, the 15-minute timing, the relocated Test Range switch, the Central Garden elevator, the Desmoulins access system, and the practical mistakes to avoid.
Quick answer: Test Range and Centrifuge Facility are always part of the three active Switch Points. The third is randomly assigned to Black Chamber or Buoyancy Lab after 15 minutes. Activate any two to unlock Helicopter Extraction.

How Space City Extraction Works in Season 11
The easiest way to understand the Season 11 extraction changes is to forget the old fixed-route mentality.
There are four locations that can serve as Switch Points on the updated Space City map:
- Test Range
- Centrifuge Facility
- Black Chamber
- Buoyancy Lab
However, you won't have to activate all four.
Only three Switch Points are active in a match:
- Test Range
- Centrifuge Facility
- Black Chamber OR Buoyancy Lab
The randomized Switch appears at Black Chamber or Buoyancy Lab after 15 minutes, while two active Switch Points are required to open the Helicopter Extraction.

🚁 Helicopter Extraction
That's the mechanic you need to remember before entering a Space City match.
You do not need to search all four locations.
You also do not need to activate all three active Switch Points.
The 3 Active Switch Points Explained
The updated system has two fixed Switch Points and one randomized Switch Point.
Fixed Switch Points
The two fixed locations are:
- Test Range
- Centrifuge Facility
These are part of the active Switch Point setup every match.
Random Switch Point
The third location is randomly selected between:
- Black Chamber
- Buoyancy Lab
Only one of those two locations is active as the randomized Switch Point during a given match.
This is important because you don't need to travel to both locations.
If Black Chamber is selected, Buoyancy Lab is not your third active Switch Point.
If Buoyancy Lab is selected, Black Chamber is not your third active Switch Point.
The random Switch also doesn't become available immediately. It unlocks after the match has been underway for 15 minutes.
Test Range Switch Location
The Test Range Switch Point was relocated in Season 11, making this one of the most important locations for returning Space City players to relearn.
How to find the new Test Range Switch
Instead of relying on the old Season 10 location, look for the higher vertical section of Test Range.
The useful landmarks are:
- The upper Test Range level
- The vertical ladder/rung access
- The yellow staircase
- The wall-mounted electrical/control panel
- The green ! objective marker
The Switch is mounted on the wall beside the staircase, with the objective marker helping identify the correct section.
The important change
The switch is higher than the familiar previous-season position.
That means following an old Space City guide can send you toward the wrong floor.
If you already know the Season 10 Test Range route, don't automatically stop at the old switch location. Use the vertical access and continue toward the upper section.
Test Range approach
Once you reach the correct section, look for the wall-mounted Switch console beside the staircase.
Because the area can leave you exposed while interacting with the terminal, reaching the switch doesn't necessarily mean you're safe to activate it immediately.
Practical tip:
If you're returning after Season 10, learn the vertical approach first. The biggest mistake here is remembering the old location and searching the wrong level.
Centrifuge Facility Switch Location
The Centrifuge Facility Switch Point remains one of the fixed Switch Points in the Season 11 system.
The switch is positioned near a red-lit staircase, with the terminal at the upper landing.
What to look for
- Centrifuge Facility interior
- Red-lit staircase
- Upper landing
- Wall-mounted Switch Point
- Narrow approach around the stairwell
The staircase is an important landmark because it gives you a clear reference point when navigating the facility.
Be careful at the staircase
The Switch is positioned around a natural approach/chokepoint.
That means another squad holding the upper landing can make the interaction dangerous.
Before committing to the Switch:
- Check the immediate approach.
- Clear or watch the upper landing.
- Make sure your squad is covering the interaction.
- Activate the Switch once the area is reasonably secure.
Season 11 also adjusts certain unbalanced positions around Centrifuge Facility, so don't assume every engagement angle is identical to Season 10.
Black Chamber or Buoyancy Lab Random Switch
This is the biggest change to the Space City Switch Point system.
The third Switch Point is not permanently assigned to one location.
Instead, it appears at either:
- Black Chamber
- Buoyancy Lab
Why the random location matters
You can't simply use exactly the same extraction route every match anymore.
A route that worked in one Space City match may be inefficient in the next because the third active Switch could be on a different part of the map.
The practical process is:
- Check the tactical map.
- Identify which random location is active.
- Decide whether it fits your current position.
- Combine it with Test Range or Centrifuge Facility.
- Activate any two active Switch Points.
Black Chamber
If the random Switch appears at Black Chamber, you can combine it with either:
- Test Range
- Centrifuge Facility
You do not need to visit Buoyancy Lab.
Buoyancy Lab
If the random Switch appears at Buoyancy Lab, the same rule applies.
You can combine it with either fixed Switch Point.
You do not need to visit Black Chamber.
Don't overcomplicate the random Switch
The important thing isn't memorizing four extraction routes.
It's understanding the structure:
Test Range + Centrifuge Facility + one random location
Then: activate any two.
When Does the Random Switch Activate?
The Random Switch Becomes Available After 15 Minutes
This is one of the most important timings to remember in Season 11.
The randomized Switch Point at Black Chamber or Buoyancy Lab becomes available 15 minutes after the match starts.
That means you shouldn't plan your opening rotation around immediately activating this Switch.
A better approach
- Early match: Loot, complete your normal objectives and position your squad.
- Approaching 15 minutes: Monitor the tactical map and identify the randomized Switch location.
- After 15 minutes: Rotate toward Black Chamber or Buoyancy Lab if that location fits your extraction plan.
- For helicopter extraction: Activate the randomized Switch plus either Test Range or Centrifuge Facility.
Alternatively, if the two fixed Switches are more convenient or safer, you can activate Test Range + Centrifuge Facility.
Why the 15-minute requirement matters
The timing makes the randomized Switch less of an opening-minute objective.
It also means you shouldn't waste the first part of the raid sitting beside Black Chamber or Buoyancy Lab waiting for an interaction that isn't available yet.
For practical purposes, treat the random Switch as a mid-match extraction option.
How to Activate Helicopter Extraction
You only need two active Switch Points.
The process is straightforward.
Step 1: Identify the active Switch Points
You will have:
- Test Range
- Centrifuge Facility
- Black Chamber or Buoyancy Lab
Step 2: Choose your route
Pick the two Switch Points that make the most sense based on:
- Your current location
- Available time
- Enemy activity
- Your intended extraction route
- The risk of crossing the map
Step 3: Activate the first Switch
Reach the terminal and complete the interaction.
Step 4: Activate the second Switch
Rotate to another active Switch Point and activate it.
Step 5: Use Helicopter Extraction
Once two active Switch Points have been activated, the Helicopter Extraction Point becomes available.
Remember: You don't need all three
This is probably the easiest mistake to make when learning the new system.
You have:
- 3 active Switch Points
but only:
- 2 required
So once your squad has successfully activated two, there is no reason to travel to the third Switch Point just to complete the set.
Where Is the Helicopter Extraction Point?
Knowing how to activate the helicopter is only half of the process.
You also need to know where to go once the extraction becomes available.
The Helicopter Extraction Point is around the central/Black Chamber side of Space City, with the helicopter marker providing the final navigation reference once the required Switches have been activated.
The important thing to remember
The Switch Points and the Helicopter Extraction Point are not the same location.
Your job is:
↓
Helicopter Extraction becomes available
↓
Move to the helicopter extraction marker
This distinction matters because activating the second Switch doesn't mean you are already standing at extraction.
Plan the final rotation
Once the second Switch is activated:
- Check the extraction marker.
- Watch for other squads rotating toward the same area.
- Don't assume the shortest path is automatically the safest.
- Keep enough time to reach the helicopter.
The new Switch system changes how you unlock the helicopter, but you still need to survive the final rotation.
Central Garden One-Way Elevator
The other major Space City change is the new Central Garden executive elevator.
This is not simply another normal elevator added to the map.
It provides a special route toward the upper executive/CEO area and is tied to the Desmoulins access system.
Where is the Central Garden elevator?
The elevator is around the Central Garden lower/mezzanine approach.
Useful landmarks include:
- Central Garden
- The escalator approach
- Stackable cargo containers
- Elevator doors
- The call console beside the elevator
The dedicated console next to the elevator is the key visual landmark.
What does the elevator do?
The elevator provides a shortcut from the lower/mid-level portion of Central Garden toward the upper executive area.
This can be valuable when your squad needs to reach the upper section without taking a more conventional route.
The important limitation: One-way
The elevator travels upward only.
You cannot simply use the same elevator to return to the lower level.
So don't enter it without considering what you're going to do after reaching the upper area.
Treat the Central Garden elevator as a commitment, not a normal two-way elevator.
This is particularly important if your squad is already under pressure.
How to Get the Desmoulins Access Card
The Central Garden elevator is connected to the special Desmoulins access system.
If you're playing G.T.I. and defeat a player-controlled Desmoulins, you can obtain the special Access Card from the mezzanine and use it with the associated special route.
The basic flow
↓
G.T.I. obtains the special Access Card
↓
Reach the relevant Central Garden route
↓
Use the special access
↓
Take the executive elevator upward
The important point is that this isn't simply a normal public elevator that every player can use.
Keep the mechanics separate
The Access Card is part of the Desmoulins access system.
The executive elevator is the special upward route.
Don't assume every part of the Desmoulins extraction system is interchangeable just because they are connected to the same update feature.
Plan around the one-way route
Because the elevator only travels upward, make sure your squad knows where it wants to go next.
The elevator can provide valuable access to the upper area, but it can also leave you committed to the next part of your rotation.
Best Way to Plan Your Extraction
The biggest difference between the old and new system is that you should now plan around the active Switches rather than memorize one route.
Early match
Don't immediately rush toward the randomized Switch.
Instead:
- Loot normally.
- Build your position.
- Track the tactical map.
- Remember the fixed Test Range and Centrifuge Facility locations.
- Wait for the 15-minute point before committing to the random location.
Mid-match
Once the random Switch becomes available:
- Check whether it is at Black Chamber or Buoyancy Lab.
- Look at your current position.
- Compare the available routes.
- Choose two Switch Points.
- Avoid unnecessary rotations through high-risk areas.
Before extraction
Once two Switch Points are activated:
- Confirm the helicopter extraction marker.
- Plan your final rotation.
- Expect other squads to understand the same mechanic.
- Don't automatically repeat your Season 10 route.
The new system rewards players who adapt rather than simply follow a memorized path.
Central Garden elevator strategy
The Central Garden elevator is better viewed as a special shortcut/high-value access route rather than another ordinary Switch.
If you have the required Desmoulins access, it can provide a useful way to reach the upper area.
But because it only travels upward, you should know your next route before using it.
What Changed From Season 10?
If you're returning from Season 10, these are the Space City changes that matter most:
For the complete Season 11 changes beyond Space City, see our Delta Force Season 11 (Reorientation) Patch Notes: What Changed From Season 10 guide.
That article covers the broader Season 11 changes, including:
- Seasonal mission changes
- Tide Prison requirement changes
- Collector requirements
- Drag Rescue
- Rover and Clover
- Layali Grove 2.0
- New weapons
- New vehicle
- Warfare changes
- Other Season 11 additions
This Space City guide is intentionally narrower: it focuses on where the extraction mechanics are and how to use them.
Space City Extraction Mistakes to Avoid
- Searching all four Switch locations
You don't need to. There are four possible locations, but only three active Switch Points in a match. The randomized one is either Black Chamber or Buoyancy Lab. - Rushing to the random Switch immediately
The random Switch Point becomes available 15 minutes into the match. Don't waste the opening minutes waiting beside a location that isn't active yet. - Following the old Test Range route
The Test Range Switch was relocated in Season 11. If you're using an old guide or relying entirely on Season 10 memory, you can easily search the wrong level. - Assuming both Black Chamber and Buoyancy Lab are active
They aren't. Only one of them serves as the randomized third Switch Point in a given match. - Trying to activate the Central Garden elevator without the required access
The executive elevator is tied to the special Desmoulins access system. It isn't simply another public elevator. - Expecting the elevator to work both ways
It doesn't. The Central Garden executive elevator is a one-way upward route. - Activating all three Switch Points
You don't need to. Two active Switch Points are enough to enable Helicopter Extraction. - Automatically repeating your Season 10 extraction route
Season 11 introduces more variation into Space City's extraction setup. Check the active Switch Point before committing to your route. - Confusing Switch activation with extraction itself
Activating two Switch Points only unlocks the Helicopter Extraction. You still need to rotate to the helicopter and survive the final extraction.
Delta Force Season 11 Space City FAQ
How many extraction Switch Points are there in Space City Season 11?
There are three active Switch Points per match, selected from four possible locations: Test Range, Centrifuge Facility, Black Chamber and Buoyancy Lab.
Where can the random Space City Switch Point appear?
The randomized Switch Point can appear at Black Chamber or Buoyancy Lab.
When does the random Space City Switch activate?
The randomized Switch Point becomes available 15 minutes after the match starts.
How many Switches do you need for helicopter extraction?
You need to activate two of the three active Switch Points.
Can I activate Test Range and Centrifuge Facility without using the random Switch?
Yes. The helicopter requires any two active Switch Points, so the two fixed locations can be enough.
Where is the new Test Range Switch?
The Test Range Switch has been relocated to a higher position within the Test Range area. Look for the updated vertical route, ladder/rungs and yellow staircase leading toward the wall-mounted Switch.
Where is the Centrifuge Facility Switch?
The Centrifuge Facility Switch remains one of the fixed Switch Points and can be reached through the facility's interior route, including the red-lit staircase and upper landing.
Where is the random Switch?
The third Switch can appear at Black Chamber or Buoyancy Lab. Only one of those locations is active in a given match.
Where is the Helicopter Extraction Point?
After activating two Switch Points, follow the newly available helicopter extraction marker. The extraction is around the central/Black Chamber side of Space City.
Where is the Central Garden elevator?
The new executive elevator is located around the Central Garden lower/mezzanine approach, near the escalator/cargo-container area and its dedicated call console.
Can the Central Garden elevator go back down?
No. It is a one-way upward route.
Can normal players use the Desmoulins elevator?
Players need the appropriate Desmoulins access. If you're playing G.T.I. and defeat a player-controlled Desmoulins, you can obtain the special Access Card from the mezzanine and use the associated special route.
Do I need to activate all three Space City Switch Points?
No. Activate any two of the three active Switch Points to enable Helicopter Extraction.
Do Black Chamber and Buoyancy Lab both have active Switches in the same match?
No. The Season 11 system randomly selects one of them as the additional Switch Point.
Final Takeaway
Season 11 makes Space City extraction less predictable, but the new system is easy to understand once you remember three numbers:
4 possible locations → 3 active Switch Points → 2 required for helicopter extraction.
The two fixed Switch Points are Test Range and Centrifuge Facility, while the third randomly appears at Black Chamber or Buoyancy Lab after 15 minutes.
The other major change is the Central Garden executive elevator, which provides a one-way upward route tied to the special Desmoulins access system.
If you're returning from Season 10, the three things worth relearning first are:
- The relocated Test Range Switch
- The randomized Black Chamber/Buoyancy Lab Switch
- The Central Garden one-way elevator
And remember: activating two Switches unlocks the helicopter — you don't need all three.
For the rest of Season 11's changes, including the new Operator, mission progression changes, Layali Grove 2.0, weapons, vehicles and broader Operations/Warfare updates, continue with our Delta Force Season 11 (Reorientation) Patch Notes: What Changed From Season 10 guide.
Once those Space City mechanics are familiar, the new extraction system becomes much easier to plan around.
