Olney sewers

The Olney sewers is a sewer system located in Old Olney. The Olney sewers is the only location where you can discover the unique prototype medic power armor.

Location
The entrance to the Olney sewers can be quite difficult to stumble upon. The round sewer manhole entrance is located between two ruined buildings in the southwest corner of town.

There is also a "trap-door" grate in the North-East corner of Old Olney, two blocks north of the fire station. Once falling inside this small pit, the only exit out is a door leading to the Olney sewers.

(NOTE: If you have fallen into the "trap", remember that you are still outside and can fast-travel to free yourself provided there are no deathclaws or other hostiles nearby.)

Enemies

 * The Olney sewers are infested entirely with deathclaws. Be very well prepared before proceeding.
 * If you go on the most direct path to get to the prototype medic power armor you will come across about 3-4 deathclaws but if you go exploring the whole sewers area you will run into about 6-7.

Nearby points of interest

 * In a room to the north, not far from the "trap-door" entrance, is a terminal that activates a unique taxi-colored protectron for a "Maintenance Routine". The protectron will detect a "critter of unusual size" and run an "extermination program". There is also a utility worker ID next to a skeleton, which will keep the robot from attacking you. Once the robot has identified you as a utility worker, it will start a patrol of the sewers. Following along behind the robot as it patrols will give any enemies encountered a primary target that isn't you, allowing you to attack in coordination with the robot, making clearing the sewers considerably easier. With a high enough sneak skill, or by utilizing a Stealth Boy, the protectron will resume its "Maintenance Routine" without the utility worker ID, and will only attack the player once all deathclaws in the sewers are exterminated, or they no longer detect the player.
 * The three safes - In the second to last room in the sewers; if you take notice of the clock on the wall you will notice there are three safes around it. Each safe has an average lock pick level. The safes usually don't have any notable rarities in them and can be overlooked, however it is possible for all of them to contain Stealth Boys.

Appearances
The Olney sewers appears only in Fallout 3.

Behind the scenes
The "critter of unusual size" line could be a reference to the book and movie The Princess Bride, wherein R.O.U.S.'s (rodents of unusual size) are prominently featured.
