Machine Graveyard

The Machine Graveyard is located at the sea floor outside Operations. As its name suggests, it is a machine graveyard, filled with all kinds of electronics dumped after they broke down or became obsolete.

History
Originally, the airlock was placed at Operations to allow divers and Big Daddies to access the seafloor. However, as garbage disposal services were expensive in Rapture, dumping broken electronics on the seafloor was seen as a cheap alternative. As a result, the seafloor became littered with all kinds of broken machinery. After Reed Wahl locked Minerva's Den down, no maintenance was done to the exterior of the buildings, adding pieces of broken walkways and bathysphere guidance brackets to the graveyard.

Minerva's Den
After fighting a horde of splicers send by Reed Wahl in the central hall, the door leading to the airlock is unlocked. As a signal beacon is necessary to escape Rapture, Sigma must obtain one from the machine graveyard.

Hallway
The hallway features an El Ammo Bandito, a Bot Shutdown Panel, a few chairs and an Audio Diary: The Man and the Machine hooked to the wall above an upgraded Shotgun. The entrance leading to the Airlock itself is guarded by a Security Camera. Water is leaking down from the ceiling and slowly flooding the floor down at the airlock.

Airlock
The Airlock itself is divided in two sections, an empty room containing a window showing the seafloor, a Gene Bank and two hatches for turrets, and the airlock itself, preceded by a changing room for divers. The desk contains the Audio Diary Signal Beacon. At the moment of arrival, a splicer has stuck his finger in a socket, causing the small layer of water to become electric and frying the splicer. After hacking the panel, Sigma can safely advance towards the seafloor.

Seafloor
The seafloor is littered with all kinds of machinery, including a bathysphere with a Signal Beacon. Passing by broken walkways and computers, Sigma can find several Sea Slugs hidden on the seafloor. After reaching the top of the rubble with the downed bathysphere, Sigma can take the Signal beacon to reprogram it in the Programming Wing.
