Patna-0
BSP_Torrens Used The Torrens, including the hypersleep area, canteen, medical area and bridge.

Solace Used Originally presumed to be a map for the cut ship known as The Solace, this map is used for the internals of The Anesidora in the final game. The Solace can be seen in concept art and animation references in the game files. Some textures remain in the game from when the map was presumably used for The Solace.

TECH_RnD_HzdLab Used The KG348 Research Labs, which holds 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.

SCI_AndroidLab Used Seegson Synythetics, including the Components Warehouse. This map also contains the Android Disposal and Synthetic Showroom areas.

SCI_HospitalLower Used San Cristobal Medical lower, 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 KG348 Research Labs. In the final game a debug checkpoint for the E3 mission can be found along with lots of script names referencing E3. Additionally dialogue and subtitle files can be found for the E3 mission, which was slightly different to the one found in the final game (mission 6).
Lower
SCI_HospitalUpper Used San Cristobal Medical upper, including Kuhlman's office, Psychiatric Wards, Staff Quarters and Patient Rooms.
Upper
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.

Engineering Decks

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.
Nest
ENG_CoolingPlant Cut A map cut from the final game, to take place in Sevastopol's Cooling Plant. There is some concept art which seems to depict the Cooling Plant.
Cooling
ENG_DryDock + ENG_DryDockCargo Cut The Dry Dock is the area where 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. There isn't a lot known about either of these maps, however they would have most likely been a large open area. 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.
Dock
ENG_Gravity_Anchor Cut This was a large map that Amanda would visit in the mission codenamed "M29_PLAN_B". She would turn off the gravity anchors causing Sevastopol to begin crashing into the planetoid. Lots of concept art exists of the gravity anchors, so it is presumed to have made it quite far into development. Limitations from the game's CATHODE Engine may have made this map run poorly, similar to the Dry Docks map, due to the large open areas. Perhaps this would explain why the story was changed and the maps were subsequently cut.
Gravityanchors
ENG_ReactorCore Used This map includes the Reactor Core and Facility Management areas.
Reactor
ENG_TowPlatform Used This map includes the Tow Platform, second nest (plus the areas leading away from the nest) and docking clamp.
Towplat
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.
Wastechute
ENG_WasteManagement Cut A map cut from the final game, to take place in the Waste Management area of Sevastopol. There is some concept art that seems to show this area.
Management
