Foundry

The Foundry is the third level of Doom (2016). It is an and as such is filled with hazardous molten liquid metal. The Praetor suit does not offer sufficient protection from the heat if the player comes in contact with the metal, and so it must be avoided. The third mission, Meltdown, takes place here after VEGA alerts the Doom marine and Dr. Samuel Hayden that the demons have shut down the cooling turbines and could cause a catastrophic explosion to occur.

"With the satellite back online, the full scale and origin of the attack is revealed. Olivia Pierce, the Lazarus Project's lead scientist turned cult leader, attacked a Hell wave and released hundreds of demons from their holding cells in the Lazarus Laboratories. The devastation that followed has left the facility on the brink of complete destruction - the Foundry reactors are in critical meltdown. Samuel Hayden, a survivor and Head of the Mars facility has offered you his help if you need it. You don't. You just need ammo and a way to stop the meltdown before it tears the base apart."

Description
The foundry is the primary processing location for heavy elements mined from areas surrounding the UAC Mars Base, including the Argent Fracture. Elements processed here, in particular transitional metals and noble gasses, are required for refinement of Argent plasma. The Foundry is a high risk area due to volatile materials and high-temperature metals, so workers assigned to it are given regular "med-checks."

As of 2146, employees exposed to hazardous materials began being sent to the Lazarus Labs for "cleansing," "re-education" and, where possible, "reintegration". This is stated to have resulted in a dramatic drop in official casualties.

Mission 03: Meltdown
After learning from VEGA that the foundry is about to experience a critical meltdown, the Doom marine travels there to reactivate the cooling turbines. On arrival at the foundry the marine finds that the turbine room is locked down due to a demonic incursion, which can only be lifted by destroying four gore nests in the area. After destroying all the nests, the marine proceeds to the turbine room and reactivates the turbines; they are then informed by Samuel Hayden that a primary control room has been activated nearby, where the marine finds Olivia rerouting all available power to the Argent Energy Tower to create a portal between Mars and Hell. Hayden explains that the system will not allow anyone but Olivia to shut down the tower, so it will have to be shut down manually from the surface; the marine travels to the Argent Facility to put this plan into operation.

Trivia

 * At, producer Marty Stratton displayed a beta version of the level on a much earlier build of what was still considered , and mentioned that this level began as part of the original Doom 4 concept which was abandoned and rebooted. While undergoing massive revisions during the re-development of the game and being greatly expanded into its final, vastly non-linear layout in the process, this makes it one of the largest known surviving relics from the previous concept.
 * If the Doom marine dies while standing in molten metal, they will give a thumbs-up as they sink below the surface. This is a reference to one of the final scenes of , where the T-800 is lowered into molten steel and gives a thumbs-up as it is destroyed.
 * There are several dead possessed, including possessed soldiers, that can be found throughout the level. It is unknown how these demons died.
