To unlock fast travel in Mortal Shell II, complete the opening progression, return the collected Ova to Marrow Keep, and use the Ovum Siphon chamber. Launch-day guides report that the system activates after enough Ova have been returned, with one source specifying at least four. Afterward, interact with a cleansed Beacon to travel between available Beacons.

Check the early-game requirement for fast travel
Fast travel is not available from the start. The durable mechanic is tied to Marrow Keep, Ova, the Ovum Siphon chamber, and cleansed Beacons. Current launch-day coverage agrees on that route, but the reported threshold is not presented identically everywhere.
GamesRadar reports that fast travel activates after returning at least four Ova to Marrow Keep. Rock Paper Shotgun also identifies the Ovum Siphon chamber as the key step, while GameRant places the first method after the prologue and the return to Marrow Keep.
Use the requirement shown in your current save as the final check. If your objective has not asked you to return Ova, continue the opening progression instead of searching for a hidden travel menu.
Return Ova to Marrow Keep and find the Ovum Siphon
- Finish the prologue or the early objective that leads you back to Marrow Keep.
- Enter Marrow Keep with the Ova you have collected.
- Locate the Ovum Siphon chamber inside the keep.
- Interact with the chamber and follow the displayed prompt to return or siphon the Ova.
The important checkpoint is the chamber interaction, not merely carrying Ova in your inventory. Fast travel should not be expected until the game registers the Ova at Marrow Keep.
After the required amount is processed, look for a clear change in the available Beacon interaction or an objective update. If nothing changes, confirm that the Ova were deposited rather than only brought into the keep.
Verify the fast-travel option at a cleansed Beacon
- Travel to a Beacon that you have already cleansed or activated.
- Stand close enough for the Beacon interaction prompt to appear.
- Open the interaction options and look for the travel command.
- Select a destination from the Beacons currently available to your save.
Fast travel works through Beacons rather than from any point on the map. A Beacon can therefore be visible without being a valid destination. The expected result is a destination list containing other available Beacons, followed by a loading transition or relocation to the selected area.
If the prompt appears but a destination is missing, return to that location and check whether its Beacon has been cleansed. Discovery alone does not prove that a location is ready for travel.
Fix a missing Beacon travel prompt
First, separate an unlock problem from a Beacon problem. If no Beacon offers travel, return to Marrow Keep and check the Ovum Siphon and the current objective. If one Beacon works but another does not, the missing location is more likely uncleansed, undiscovered, or restricted by progression.
- Recheck the Ova deposit in the Ovum Siphon chamber.
- Confirm that the launch-day threshold has been met; GamesRadar specifies at least four returned Ova.
- Leave the chamber, save or change areas if the game permits it, and revisit a known cleansed Beacon.
- Reload the save once if the requirement is complete but the prompt still does not update.
Do not assume that a missing prompt means the entire system is permanently unavailable. The prompt can be absent at an uncleansed Beacon even after the global fast-travel route has opened.
Distinguish the durable route from launch-day details
The durable navigation guidance is to process Ova at Marrow Keep, then use cleansed Beacons as travel points. The exact early-game trigger is a launch-day fact: published reports place it after the prologue and the Ova return, while one report gives a minimum of four Ova.
That threshold may be displayed differently after a game update or in another progression state. If the current game shows a different objective, requirement, or interaction label, follow that in-game state and stop before applying the older count.
Frequently asked questions
Can you fast travel from anywhere in Mortal Shell II?
No. The reported system uses Beacons as travel points. You need to interact with an eligible Beacon, and the destination must also be available to your save. A map location that you have visited may still be unavailable if its Beacon has not been cleansed.
How many Ova are needed to unlock fast travel?
Launch-day coverage is not completely uniform, but GamesRadar specifies at least four Ova returned to Marrow Keep. The reliable check is the current objective or Ovum Siphon response in your save. Do not treat four as universal if the game displays another requirement.
What is the Ovum Siphon used for?
The Ovum Siphon is the Marrow Keep chamber used to process or return collected Ova. It is the key progression checkpoint associated with opening fast travel. Carrying Ova back to the keep is not enough if you have not completed the chamber interaction.
Why is one Beacon missing from the travel list?
The Beacon may not be cleansed, activated, or fully available in the current progression state. Visit that location again and check for its activation interaction. If every Beacon is missing from the list, recheck the Ova requirement and the Ovum Siphon instead.
