Alien: Isolation maps

This article covers the known maps in the 2014 video game Alien: Isolation, including every map in the released game as well as the known unreleased maps that were cut from the finished product.

Off Sevastopol[]

Map Name	Status	Description	Picture
BSP_LV426_Pt01	Used	LV-426, including the Anesidora hangar and view over to the derelict.
BSP_LV426_Pt02	Used	LV-426, inside the derelict.
BSP_LV426_Pt03	Cut	LV-426, cut from the game, presumed to be inside Anesidora. This can be seen in some concept art.
BSP_P01_TwoTeams	Cut	A map cut from the game, presumed to be a prologue to the main campaign where the player could control multiple characters, similar to how the Crew Expendable DLC works.
BSP_Patna	Cut	The Patna, a medical transport vessel cut from the game. This can be seen in multiple pieces of concept art.
BSP_Torrens	Used	The Torrens, including the hypersleep area, canteen, medical area and bridge.
Solace	Used	Originally for the Solace, this map was re-purposed as the interior of the Anesidora in the final game. The Solace can be seen in concept art and animation references in the game files.

Sevastopol - Lorenz SysTech Spire[]

Map Name	Status	Description	Picture
TECH_Comms	Used	Seegson Communications, including the external comms array.
TECH_Hub	Used	The central area of the SysTech Spire that the transit connects to. Includes the server hub, archive room and Lorenz SysTech lobby.
TECH_MuthrCore	Used	APOLLO, including the server banks.
TECH_RnD	Used	Gemini Exoplanet Solutions
TECH_RnD_HzdLab	Used	The Project KG-348 research labs, including the detachable lab. This section was used heavily in pre-release screenshots and videos, as well as the first playable demo. The first playable demo was nicknamed "Showlevel" and some demo-specific script names can be found in the game, along with some fog for the demo opening sequence. The "Showlevel" demo is still able to be seen on SteamDB, however unfortunately it is not open to the public for download.

Sevastopol - SciMed Tower[]

Map Name	Status	Description	Picture
SCI_AndroidLab	Used	This map contains the entirety of Seegson Synthetics. This includes the Components Warehouse, Android Disposal, the Synthetic Showroom and Facility Administration. The transit station to APOLLO can be found here.
SCI_HospitalLower	Used	San Cristobal Medical lower floors, including the Ambulance Bay, Medical Reception, Medical Wards and Operating Theatre. This area was also used a lot in pre-release demos similar to the Project KG-348 labs. Mission 6 in the final game (M10_HOSPITAL_PLAYABLE) ended up using an alternate version of the E3 demo on this map, utilising a series of different animations and sequences from the original non-E3 mission.
SCI_HospitalUpper	Used	San Cristobal Medical upper floors, including Dr. Kuhlman's office, Psychiatric Wards, Staff Quarters and Patient Rooms.
SCI_Hub	Used	The central area of the SciMed Tower where the transit arrives, leading to the upper and lower areas of San Cristobal Medical, and Seegson Synthetics. The Transit Control area can be accessed through an elevator.

Sevastopol - Solomons Habitation Tower[]

Map Name	Status	Description	Picture
HAB_Airport	Used	The area where Amanda initially arrives on Sevastopol, including the Spaceflight Terminal and baggage reclaim area. Also contains Axel's den and lower airport sections where Axel and Amanda meet looters, believed to be repurposed from the cut ENG_DryDockCargo map.
HAB_CorporatePent	Used	The Corporate Penthouses, including the two transit waiting areas, canteen, projector room, library, entertainment terminals and games room.
HAB_ShoppingCentre	Used	The Solomons Galleria, including the Colonial Marshal bureau and transit station.

Sevastopol - Engineering Platform[]

Map Name	Status	Description	Picture
ENG_Alien_Nest	Used	The Hive below the Reactor Core, it can only be accessed through the Reactor Core on mission 14 by an elevator.
ENG_CoolingPlant	Cut	Sevastopol's Cooling Plant. There is some concept art which seems to depict the Cooling Plant.
ENG_DryDock / ENG_DryDockCargo	Cut	The Dry Dock is where Henry Marlow and Amanda go to blow up The Anesidora in the alternate storyline. Two versions of the Dry Dock (Dry Dock and Dry Dock Cargo) are found referenced in the game files, with the latter seemingly being repurposed for the lower section of HAB_Airport where Axel's den is located. A crew patch is seen in the game for the "Hangar Crew", and a cut badge is shown in concept art for the "Commercial Docks" which is possibly from the Dry Dock.
ENG_Gravity_Anchor	Cut	Amanda would visit this area in the mission codenamed "M29_PLAN_B". She would turn off the gravity anchors causing Sevastopol to begin crashing into KG-348. Lots of concept art exists of the gravity anchors as well as sounds left over in the game files, however no in-game screenshots have been seen.
ENG_ReactorCore	Used	This map includes the Reactor Core and Facility Management areas. A significant portion of this map is re-used from the game's IL3 demo.
ENG_TowPlatform	Used	This map includes the Tow Platform, second Hive (plus the ruined transit tunnels leading away from the Hive) and docking clamp.
ENG_WasteChute	Cut	The Waste Chute was an area cut from the final game which would take the player around a tall circular room, as shown in some concept art. It is possible that the player would have had to time walking around this area to avoid the waste being dumped, similar to how the player has to avoid the steam vents when walking along the ledge in Seegson Synthetics.
ENG_WasteManagement	Cut	The Waste Management area of Sevastopol. There is some concept art that seems to show this area.

Transition Maps[]

EXT_CorpToShop
EXT_TechToEng
EXT_TorrensToAirport
TRANS_HabToTech
TRANS_SamuelsExpress
TRANS_SciToHab

The EXT_* maps would have most likely been used for the inter-tower transit shuttles, which were used heavier in the game's original cut storyline. The TRANS_* maps would have been used for the transit cars. Both EXT_* and TRANS_* are from level streaming tests, loading the next map without showing a loading screen. This functionality didn't make it to the final release of the game due to time constraints, and instead, players are shown a video loading screen during level transitions.
