- "Generate a sympathetic overload in Harmonic Core #3. That's simple. Now all I gotta do is figure out what the hell a sympathetic overload is, and for that matter, a Harmonic Core #3!"
- ―Anya Andersdotter[src]
Hephaestus Core (sometimes referred to as Harmonic Core #3) is a geothermal generator, located within Rapture's Hephaestus district. It provides power to much of the equipment in Hephaestus, as well as some parts of the city.
The Core is divided into two sections: an outer ring connecting the three monitoring and maintenance areas of Hephaestus and an inner ring providing direct access to the rotating generators.

The spiraling set of stairs provide access to Heat Loss Monitoring, the Workshops, and Geothermal Control. Other facilities include a Power to the People Machine and a Gatherer's Garden. The phonograph near the Garden plays "It's Bad for Me".
Egress is normally granted via locked grates surrounding the Core or through an elevator in Geothermal Control. However, the lower area of the latter has been flooded since shortly after the start of the Rapture Civil War. Jack must drain the area using redirected magma pipes to boil off the water. He then can use Kyburz' completed EMP Bomb to overload the Core, stopping the energy flow to the power facilities security systems and allowing him access to Rapture Central Control.
Single Use EventsEdit
- There is one Power to the People machine across from the Gatherer's Garden, on the southwest corner of the Core.
