Failsafe Armored Escorts

Located in Point Prometheus, Failsafe Armored Escorts is the main facility to prisoners of Persephone were brought to be made into Big Daddies. There appears to have been multiple steps in this process.

Upon entering, Big Daddy candidates would pass through a decontamination room, which temporarily holds them while they are cleaned. After heading through this room, they would have been escorted to the Candidate Induction area, where candidates were put into a vat, making them will-less. A small trip to Optimized Eugenics for a voicebox modification follows. Then, presumably, the candidates would be taken to Suit Assembly, where, according to Dr. Suchong's audio diary "Cheap Son of a Bitch" the suits, gloves, boots and helmet would be grafted on to their skin. After this, the next step is Candidate Conversion, where the Big Daddies are placed into a large yellow chemical vat once again, to have the final modifications applied. Finally, the Big Daddies are sprayed with Big Daddy pheromone from the Optimized Eugenics area to make them attract Little Sisters.

This facility was certainly an important place, as it had a weapons storage and it's own Security Monitor Room with half a dozen Security Bots left. With the Rapture Civil War escalating, Andrew Ryan was apparently worried about attacks from Atlas's forces that might try to seize the facility.

There is a hatch leading into the ocean so the new Big Daddies could perform maintenance and other duties. Before they would actually head out into the ocean the suits would have to be tested first. Signs that the suits weren't all that "failsafe", are evident by the Rosie corpse underwater.
