The latest Fortnite UEFN prefabs and galleries give creators a new collection of Shaken Sanctuary assets for building laboratories, underground compounds, greenhouses and heavily fortified bases. Added with the Fortnite v41.30 ecosystem update, the new set includes two complete prefabs and five modular galleries.
Creators can use the ready-made structures as a starting point or pull individual walls, floors, roofs, foundations and props from the matching galleries to construct something completely different.
The new Fortnite UEFN prefabs and galleries are available through Fortnite Creative and Unreal Editor for Fortnite following the release of v41.30 on July 30, 2026.
All New Fortnite UEFN Prefabs and Galleries
The Fortnite v41.30 update adds seven Shaken Sanctuary asset collections in total.
| Asset | Type |
|---|---|
| Shaken Sanctuary Secret Facility Prefab | Prefab |
| Shaken Sanctuary Greenhouse Prefab | Prefab |
| Shaken Sanctuary Floor Gallery | Gallery |
| Shaken Sanctuary Wall Gallery | Gallery |
| Shaken Sanctuary Roof Gallery | Gallery |
| Shaken Sanctuary Base Gallery | Gallery |
| Shaken Sanctuary Prop Gallery | Gallery |
Epic officially lists two prefabs and five galleries as part of the latest Content Browser and inventory update.
Shaken Sanctuary Secret Facility Prefab
The Shaken Sanctuary Secret Facility Prefab is the largest ready-made structure in the new Fortnite UEFN prefabs and galleries collection.
It gives creators a preassembled facility that can be placed into an island and used immediately or broken apart for individual building pieces.
The overall theme makes the prefab suitable for experiences involving:
- Secret laboratories
- Underground military bases
- High-security compounds
- Research facilities
- Villain headquarters
- Escape rooms
- Stealth missions
- Extraction games
- Story-driven adventures
- Zombie or creature containment maps
A complete prefab can save a considerable amount of time during early island development. Instead of constructing every room and corridor from scratch, creators can place the building, test the gameplay layout and then modify the structure around the finished mechanics.
The Secret Facility Prefab could also work as a secondary location inside a larger open-world island. Players might discover it beneath another structure, access it through a hidden entrance or enter it as part of a quest.

Shaken Sanctuary Greenhouse Prefab
The Shaken Sanctuary Greenhouse Prefab provides a second complete building with a different visual purpose.
Greenhouse structures are useful because they can support several themes beyond ordinary plant cultivation. Depending on the surrounding props and lighting, the building could become a peaceful garden, an abandoned research site or a dangerous biological experiment.
Creators could use the Shaken Sanctuary Greenhouse Prefab for:
- Farming islands
- Survival games
- Botanical laboratories
- Alien plant research
- Post-apocalyptic settlements
- Healing areas
- Puzzle rooms
- Potion-making experiences
- Resource collection
- Environmental storytelling
The prefab could be placed beside the Secret Facility to create one connected research complex.
For example, the greenhouse might contain unusual plants being studied by scientists inside the facility. Alternatively, it could hide an entrance leading down into the underground base.
Because both buildings belong to the same Shaken Sanctuary asset set, their materials and visual language should be easier to combine than unrelated structures.
Shaken Sanctuary Floor Gallery
The Shaken Sanctuary Floor Gallery contains modular floor pieces that creators can use to expand the two prefabs or build a new layout.
Floor galleries are particularly useful when a prefab is close to the required design but not quite large enough. Creators can extend corridors, add rooms or replace sections without attempting to reproduce the original building style manually.
Possible uses include:
- Facility corridors
- Laboratory floors
- Raised platforms
- Interior rooms
- Connecting walkways
- Control areas
- Greenhouse paths
- Multi-level compounds
Creators should test floor pieces with player movement, vehicles and NPC navigation before completing a large build.
A floor that looks suitable visually may still cause problems if its height does not align with nearby pieces or if small gaps interrupt movement.
Shaken Sanctuary Wall Gallery
The Shaken Sanctuary Wall Gallery allows creators to build new rooms and expand the exterior of the prefabs while maintaining the same visual theme.
Wall galleries normally contain several variations, giving developers options for doors, windows, corners and solid sections.
The new walls could be used to create:
- Security rooms
- Research chambers
- Hidden corridors
- Storage areas
- Offices
- Observation rooms
- Containment zones
- Maintenance tunnels
A creator could also combine Shaken Sanctuary walls with assets from another Fortnite set.
For example, clean laboratory walls could transition into damaged industrial tunnels, an underground cave or an older abandoned building. Mixing asset sets carefully can make a location feel as though it has been expanded and rebuilt over time.
Shaken Sanctuary Roof Gallery
The Shaken Sanctuary Roof Gallery provides modular roof sections for covering custom buildings and modifying the existing prefabs.
Roof pieces are easy to overlook during early level design, but they can significantly affect both appearance and gameplay.
Creators can use the gallery to:
- Complete custom facility buildings
- Cover greenhouse extensions
- Create rooftop combat areas
- Add ventilation spaces
- Hide secret rooms
- Build elevated routes
- Form overhangs and covered walkways
Roofs can also become playable spaces.
A facility roof might contain security equipment, guard patrols, aerial extraction points or access hatches leading into the building. Creators should consider how players will reach the roof and whether it should be visible from surrounding areas.
Shaken Sanctuary Base Gallery
The Shaken Sanctuary Base Gallery contains structural pieces designed to support and ground the rest of the build.
These assets can be especially useful when placing a prefab on uneven terrain or creating a raised facility.
The gallery may help creators produce:
- Building foundations
- Reinforced lower walls
- Raised platforms
- Underground entrances
- Facility supports
- Exterior boundaries
- Elevated greenhouse structures
Foundation pieces can prevent a building from looking as though it has simply been dropped onto the landscape.
They also help connect the location to slopes, rocks, roads and other terrain features.
For underground builds, the Base Gallery could be used around entrances, shafts or exposed sections of the facility.
Shaken Sanctuary Prop Gallery
The Shaken Sanctuary Prop Gallery is likely to be the most flexible part of the new Fortnite UEFN prefabs and galleries set.
Props turn an empty structure into a believable location. They can communicate what happened in a room, who works there and how players are expected to use the space.
The Shaken Sanctuary props could help decorate:
- Laboratories
- Offices
- Greenhouses
- Storage rooms
- Security areas
- Medical facilities
- Control rooms
- Maintenance areas
- Research spaces
- Underground compounds
Creators should avoid filling every room with props simply because the assets are available.
A small number of carefully placed objects can direct the player’s attention, while excessive decoration may make an area difficult to navigate or harm performance on lower-powered devices.
Props can also support gameplay. A desk might hide a key, a machine could act as an objective and a storage container could mark where players should search for an item.
How to Find the New Fortnite UEFN Prefabs
The new structures should appear in the Prefabs section of the Fortnite Creative inventory or through the Content Browser in UEFN.
Creators can search for the complete asset names:
- Shaken Sanctuary Secret Facility Prefab
- Shaken Sanctuary Greenhouse Prefab
Searching for “Shaken Sanctuary” should help group the related assets together.
Once placed, a prefab can be moved, copied or modified like other compatible Fortnite building content.
Creators working in UEFN can use the Outliner and Details panel to manage the selected actors and organise larger structures.
How to Find the Shaken Sanctuary Galleries
The five modular sets should appear in the Galleries section.
Search for:
- Shaken Sanctuary Floor Gallery
- Shaken Sanctuary Wall Gallery
- Shaken Sanctuary Roof Gallery
- Shaken Sanctuary Base Gallery
- Shaken Sanctuary Prop Gallery
Placing a gallery normally adds a displayed collection of individual assets to the island.
The creator can then copy the required pieces into the main build and remove the original display once it is no longer needed.
Keeping gallery pieces in a separate development area can make it easier to compare available variations while constructing a location.
Prefabs Versus Galleries in Fortnite UEFN
Prefabs and galleries serve different purposes.
| Feature | Prefab | Gallery |
|---|---|---|
| Main purpose | Provides a complete prebuilt structure | Provides individual modular assets |
| Best for | Rapidly placing a finished location | Building customised structures |
| Editing | Can be modified after placement | Pieces are selected and placed separately |
| Development speed | Faster initial setup | More control over the final design |
| Typical use | Complete building or landmark | Walls, floors, roofs and decoration |
A creator who needs a fast starting point may prefer the Shaken Sanctuary Secret Facility Prefab.
Someone building a completely original map may use only the galleries.
The two methods can also be combined. Place the complete prefab first, then use gallery pieces to extend or redesign it.
Best Island Ideas for the Shaken Sanctuary Assets
The Shaken Sanctuary collection has enough variety to support several types of Fortnite islands.
Secret Laboratory Escape
Players wake inside the facility and must solve puzzles, avoid guards and find a route to the surface.
The greenhouse could contain ingredients required to disable a security system or produce an antidote.
Creature Containment Map
The facility has lost control of a dangerous experiment.
Players must restore power, access restricted areas and survive creatures moving through the corridors.
Team Infiltration Game
One team defends the Secret Facility while another attempts to enter, steal an item and escape.
The greenhouse can become an alternative entrance or contested objective.
Research Tycoon
Players generate resources by operating machines, studying plants and expanding the compound.
The prefabs provide a finished visual foundation while the galleries allow the facility to grow throughout the match.
Post-Apocalyptic Settlement
Survivors have transformed the facility and greenhouse into a protected base.
The greenhouse produces food while the underground rooms store equipment and supplies.
Mystery Adventure
Players investigate why the entire research team disappeared.
Props, damaged rooms and environmental clues can gradually reveal the story without relying entirely on dialogue.
How to Customise the Shaken Sanctuary Prefabs
A prefab should be treated as a starting point rather than a finished island.
Creators can customise the new structures by:
- Removing unnecessary rooms
- Extending corridors
- Replacing exterior walls
- Adding entrances
- Blocking routes
- Changing lighting
- Adding devices
- Placing NPCs
- Creating quest objectives
- Adding destructible areas
- Connecting underground tunnels
- Combining other gallery sets
Lighting will have one of the largest effects on the finished atmosphere.
Bright, clean lighting could make the location feel active and controlled. Flickering lights, darkness and emergency colours could turn the same structure into an abandoned horror environment.
Sound design can also change the identity of the location. Machinery, alarms, ventilation noise and distant creature sounds can make an otherwise static building feel alive.
Using the New Prefabs With Fortnite AI NPCs
The Shaken Sanctuary assets arrived in the same v41.30 ecosystem release that allowed creators to publish islands containing LLM-powered NPCs and characters.
That creates an obvious opportunity to combine both features.
A creator could add:
- A scientist who explains the experiment
- A suspicious security guard
- A trapped researcher
- A malfunctioning facility assistant
- A greenhouse worker
- A creature attempting to negotiate with the player
- A shopkeeper selling laboratory equipment
- A quest character hiding important information
The facility setting gives AI-powered characters a clear role and purpose.
A scientist NPC could answer questions about the compound, while a security character might refuse access until the player provides the correct information.
Using Shaken Sanctuary Assets With Quests
The same v41.30 release also added new documentation for the experimental Quests API, which allows UEFN creators to define quests, objectives and rewards through Verse. These quests can appear in Fortnite’s native quest interface and tracked pause-menu display.
The Shaken Sanctuary structures could support objectives such as:
- Enter the Secret Facility
- Search the greenhouse
- Find three research samples
- Restore power
- Speak to the scientist
- Unlock the containment room
- Escape before the timer ends
- Defeat the facility guards
- Collect evidence
- Destroy the experiment
The Quests API remains experimental, so creators should verify its current publishing status before using it in a live release.
Are the New Fortnite UEFN Prefabs Free?
Epic lists the Shaken Sanctuary prefabs and galleries as new content included with the v41.30 Fortnite ecosystem update. They are part of the creator asset collection rather than a separate paid asset pack.
Creators still need access to Fortnite Creative or UEFN to use them.
Some UEFN tools and publishing systems may have separate eligibility requirements, but the listed prefab and gallery content itself is included in the update.
What the New Fortnite UEFN Prefabs Add
The v41.30 Fortnite UEFN prefabs and galleries provide creators with a complete visual set rather than one isolated building.
The Secret Facility and Greenhouse prefabs offer rapid starting points, while the Floor, Wall, Roof, Base and Prop galleries make it possible to extend those structures or create an entirely new location.
The theme is flexible enough for science-fiction islands, horror maps, tycoons, role-playing games, stealth missions and narrative adventures.
Creators who do not want to use the complete Shaken Sanctuary structures can still take individual props or building pieces and combine them with existing Fortnite assets.
That flexibility makes the new collection more useful than a pair of fixed landmarks. It gives developers enough matching content to build a larger compound with a consistent appearance while still leaving room for original layouts and gameplay ideas.
