It, and the Egg Dreadnought by extension, is one of the locations accessible from the Egg Bunker.
Aria's story begins on the Egg Dreadnought as she breaks into Eggman's storage to obtain an Egg Walker, and she battles against the Chaos Symphony to obtain it before escaping into the factory, where she seeks to deal as much destruction to the robot production line as possible before battling the Chaos Symphony again on the Egg Dreadnought deck. She then escapes into Season Ruins using a hover disc.
Tails enters the Scrap Cauldron after fighting the Egg Hydra, having no other place to go. While inside the factory, he takes the opportunity to sabotage some of the production lines. He also discovers that Amy Rose is being held on the fleet, and decides to give her a helping hand; though his discovery by the E-Series robots puts an end to this, and he is forced to escape onto the Egg Battery.
