…You can't cut off the power, comes right from the volcanic vents… Ryan always gets his juice…
― Kyburz[src]

Hephaestus (or Hephaestus Core[1]) is the eighth level of BioShock. Jack reaches Hephaestus via bathysphere from Fort Frolic. His objective here is to gain entrance to Ryan's office in Rapture Central Control, in which the city's founder has barricaded himself.



Kyburz' Office

The office of Supervisor Kyburz.

Hephaestus, home of the Hephaestus Power Facility, is the main power production source for Rapture and is located at the Southern end of the city. Designed by Andrew Ryan, it harnesses the heat from geothermal vents on the ocean floor. Hephaestus was one of the initial facilities built in Rapture; without it, Rapture could not have been powered. Hephaestus also contains the private office of Andrew Ryan. In the post-construction era, many of the specialists who built Rapture worked in the various workshops or became maintenance employees.

During the civil war, the facility was continuously attacked by rebels, as taking control of the city's main power source would have granted them victory in the war. Many workers were killed during these attacks, and a number of attempts were even made on Ryan's life. ADAM sickness and increased paranoia of being murdered lead to workers killing each other, and the workshops are now littered with the corpses of people who once kept Hephaestus functioning.

Rapture Metro StationEdit

Hephaestus Station

Hephaestus' intimidating welcome.

The Metro station to Hephaestus is whirring with life, as massive geared machines turn in the water and large pipes in the walls and ceiling pump fluids around the facility. The station, decorated with Ryan's image of strength, is far cleaner than any of the others visited by Jack, but the metal floor and wall paneling makes the station feel harsher than any of the others.

A glass tunnel circles a large rock formation on the sea floor and connects to the main building. The tunnel is mostly empty save for two Splicers.

Central ControlEdit


You don't need signs to see that this place is dangerous.

Central Control is made up of a series of rooms in which the monitoring and distribution of power generated in Hephaestus was overseen. The first is the entry point to Ryan Industries. A dislodged pipe in this chamber leads to a hiding space. In the next area, an unseen Splicer attempts to lure Jack into a false sense of security with lavish gifts, but it's an ambush. The next room is the most gruesome in Central Control: Ryan's Trophy Room.

This room is on the way to the control center and office of Andrew Ryan, which is guarded by an electromagnetic lock system. Here various corpses — including those of Anya Andersdotter and Bill McDonagh — are impaled on the pillars, as part of Ryan's morbid warning display.

Hephaestus-Cent Control-02

"It's a regular convention of worm."

Upon entering the room, Ryan delivers an unsettling sermon, referring to his trophies as "worms", and tells Jack that he is no different from those others who have tried and failed to assassinate him. He menacingly concludes his speech by saying: "I haven't chosen a spot for you on the wall yet… let me know if you have a preference."

The Breadwinner Splicer model can be heard referencing this trophy collection if one listens to his dialogue. Supervisor Kyburz also mentions it in his audio diary, Device Almost Finished.

The audio diary found on Anya Andersdotter's corpse gives a clue for an ersatz method of breaking into Andrew Ryan's barricaded office.

Heat Loss MonitoringEdit

Most of the machinery for regulating heat transfer from the geothermal fluid is located here. On the lower levels, Jack finds an audio diary hinting the location of an EMP bomb.


Here are various workshops for Hephaestus including Kyburz' office. Hidden behind a crawlspace door, Jack will find Kyburz' incomplete Electromagnetic Pulse Bomb. Jack must locate the missing parts around Hephaestus.

Geothermal ControlEdit

This facility directs the flow of hot fluid from the geothermal vents. Jack redirects the pipes to boil away the water while under an onslaught by Splicers. Afterwards, an elevator takes him down to the Core.

Geothermal CoreEdit


Harmonic Core #3.

The huge machinery of Harmonic Core #3 serves as one of the primary power sources for Hephaestus. Jack disables the core by creating a sympathetic overload with Kyburz' completed EMP bomb.

First Room

Second Room

Ryan's Trophy Room

  • Upon entering, go right to see a locked door where Splicers will enter.
  • Ryan's office door is at the far end and is protected by a electromagnetic lock.
  • Searching the last hanging body on the right triggers an attack.
  • Search all the bodies but that one first.
  • Door in middle of right platform opens to a flooded room.
  • Set Proxy Mines, gas tanks, Cyclone Traps, and Trap Bolts around.
  • Search the last body and move to the end of the platform facing the Splicers' door.

  • When done, exit through the now-open door and turn left.
  • Go through another flooded room with a dead Big Daddy in the middle to…

Hephaestus Core

Logo of the Hephaestus core.

  • Raised walkway: with luck, there'll be a Big Daddy below.
  • This is an easy kill because he has to run upstairs to get Jack.
  • It's recommended to set traps on the ramp leading to Jack before attacking the Bouncer.
  • Much later, the player will have to kill two other Big Daddies, so lay off them until then.
  • Reload while he runs upstairs and finish off his last little health.
  • There is an Audio Diary on this level.
  • Napalm by the machines next to stairs. First Aid Kit ("FAK") on the machine opposite it.
  • Go downstairs.
  • Liquid Nitrogen ahead to the right. Gatherer's Garden ahead to the left. Audio Diary next to it.
  • Power to the People station opposite the Gatherer's Garden.

  • The lights will go out momentarily. Nothing happens the first time, so don't worry.
  • After the lights go out the second time, Napalm the "corpses" at the end.
  • From this moment on, some Splicers will pretend to be dead.
    • The best way to check a corpse is to use Telekinesis ("TK"). If the "corpse" doesn't come to the player, then it's a live Splicer.

  • Pneumo tube on the right. Ahead: Audio Diary, Coffee, lockbox.
  • Cross the stairs to a CoV with a lockbox by its left side.

  • Go back to the flooded room with the dead Big Daddy in the middle.
    • A Splicer may be playing dead in front of the door to the glass tunnel.
      • Loot the third R-34.
  • Return to the core and find another Big Daddy.
  • This one will have full health.
  • That is the last R-34.
  • There are plenty of Ionic Gel cans around the core, so it's rather easy to find them.
  • Run all the way back to the crawl space to avoid any more Splicers.
  • There's often another faker just before crawl space entrance.
  • Complete and pick up the bomb.

  • On to Rapture Central Control.


Behind the ScenesEdit

  • Hephaestus was the Greek God of volcanoes, blacksmithing, and forging,[2] making it an appropriate name for such a place.
