Reilly's Rangers (quest)

 is a Fallout 3 quest. It is also an Xbox 360 and PC achievement.

Objectives and walkthrough
Reilly's Rangers is a map service group in the wastelands of Fallout 3. There are five members of Reilly's Rangers, they are:
 * Donovan: Reilly's Rangers' engineer
 * Brick: Reilly's heavy weapons woman, uses a Minigun, which at the time is the special weapon Eugene, and therefore will take the 5mm Round found on Theo's person
 * Butcher: The Rangers' medic
 * Theo: The Rangers' quartermaster, who was carrying most of the Rangers' ammo when he was killed in action.
 * Reilly: Leader of the Rangers

This Quest can be started in two ways:

Exploring at the National Archives building near the Mall Northeast map marker, you will pick up the Ranger Emergency Frequency from Reilly's Rangers needing assistance.

You meet Reilly in Underworld, the Ghoul City situated in the Museum of History in D.C. (near the Washington Monument). Reilly was wounded by Super mutants on one of her excursions and is lying unconscious in the Underworld hospital. If you manage to wake her up (60 medicine skill) or convince the Doc to wake her up (speech skill), she will ask you to help her team of Rangers, which is trapped on a hotel roof not far away.

(Note: This Quest can also be started by free-exploring the hospital, and discovering the pathway across to the hotel via a fallen archway.)

(2nd Note: In one instance on the Xbox360 version of the game, I free-explored the Statesman Hotel without having picked up the Rangers' radio transmissions or having visited Underworld (and thus never meeting Reilly). All of the Rangers and Super Mutants on the roof were dead, and once I had repaired the elevator I received a message saying that Reilly's Rangers were now hostile toward me, and that I had failed the "Reilly's Rangers" mission.  Beware!)

Just after repairing the elevator, all Rangers rush to the ground level where, if you haven't yet given them some ammo from Theo's case, they will be no match for the waiting Super Mutants. When you first meet Butcher, you can say that you take command, but you don't have any further dialogue choices allowing you to give orders.

Directions
Reilly's directions to Statesman Hotel: "Using the Metro tunnels, head north from here to Metro Central. Then look for the tunnels to the Dupont Circle Station. Exit from Dupont Circle Station into the Dry Sewers and follow to Our Lady of Hope Hospital." These directions require a little interpretation: after leaving Dupont Circle station, you need to find East Dupont, which is a short overground walk away. At East Dupont there is a flight of steps leading down to a door marked "Hospital Maintenance", which leads into the Dry Sewers.


 * Despite Reilly's directions, an alternate (possibly easier) way to get there is to go to the Vernon Square North Station near Vault-Tec Headquarters. Go into the tunnels and head south to Vernon Square Station. Exit there and you will be in the plaza with the hospital and hotel.
 * Check out every room you pass in the hospital, as well as hacking any terminals you encounter. The terminals will be able to open the nearby safes, which contain a few stimpaks and miscellaneous other medical items, and a few caps. (50 science required to hack terminal, 75 lockpick required to open safe without using terminal). Most rooms that you pass will have a first aid kit on the inside wall. You can get about 20 stimpaks just on the first floor.


 * You can only reach the rooftop of the hotel by going through the hospital first. However, it would be wise to clear the entrance immediately inside the hotel as this will make the battle as you leave the building with the rangers much easier. After doing this, proceed to the hospital.
 * You may also want to clear the building diagonally across the street from the hotel and hospital as it contains Super Mutant riflemen in the windows.


 * The Fission Battery required to repair the elevator can be found in the room (the Statesman Hotel Restaraunt) just before you go to the roof. It can be found on a destroyed Maintenance Protectron in a supply room.


 * Ps3 Version and the Xbox 360

The Fission Battery that can be found on the broken Protectron in a supply closet in the main room of the Statesman Hotel Restaurant can be tricky to locate. Make sure you use your quest indicator on your map. Once in the main room of the Restaurant, The supply closet is underneath the stairs in the Southwest corner of the room. There is a pillar in front of the supply closet door. If you run by you won't see the door, walk around the area and you'll find the closet!

Follow the quest map indicator. Or you can just bring one. (Note: One can be found on your way through metro station in a back room. This room is located in the long hall, back right corner, before you reach the main platform. It takes an average skill of lock picking to unlock the door.).


 * Reilly's note on the location of Theo's body is a bit misleading. The note says Theo's body is in a stairwell on the 2nd floor of the Statesman Hotel.  However, this is not techically true as the 2nd floor of the hotel can be accessed through the ground floor entrance and accessed via internal staircases and balconies.  Reilly is actually referring to perhaps the 3rd floor of the hotel, which is the first floor you get to after crossing the crane boom from the hospital.


 * To recap, once you have arrived at Vernon Square, the other authors have suggested you...
 * Clear the 1st/2nd floor of the hotel, and perhaps the surrounding buildings as well, if you want to ease the Rangers' extraction from the hotel.
 * Leave the hotel, enter the hospital, and proceed up to the 2nd or 3rd floor where the crane boom connects it to the 2nd/3rd floor of the hotel.
 * Find the Fission Battery on your way up to the roof of the hotel.
 * Reach the roof of the hotel. The rest should be pretty straight forward from there.

Alternatively, instead of wasting time clearing the lobby before going to the hospital, just give each of the Rangers some ammo when you finally meet them on the roof - there's a dialogue option. With ammo (and your help) they'll have no trouble clearing the supermutants.

Rewards
The quest rewards for this are either a suit of Ranger Body Armor (which can be repaired using any combat armor) and/or Brick's special mini gun: Eugene. It is highly advised to take the armor as a reward, as you can always steal Eugene from Brick using a Stealth Boy.

After rescuing Reilly's Rangers and offering Reilly your help for their mapping service once you return to the Ranger Compound, she will give you a Geomapper Module. As long as have the module in your inventory, it will record every new location you discover, for which Reilly will pay you 30 caps per location every time you return to the Ranger Compound and talk to her. Don't forget to speak to her right away, after receiving the Module. She will pay you for the locations which you already have on your map.

The Rangers themselves will also offer services, if they lived through the journey back to their headquarters of course.


 * Donovan offers to repair your weapons and apparel; however, he charges caps for the service.
 * Butcher will emulate a normal Doctor as he can heal wounds (For free on top of that), but he cannot cure radiation poisoning or clear any addictions.
 * You can randomly encounter Donovan while traveling through the Capital Wasteland. When you talk to him, he will give you a Mini Nuke and say that Reilly sent him.

Bugs

 * If you kill the doctor in the Ghoul underworld, the quest is broken and you can't revive Reilly no matter what.


 * There is a minor bug near the conclusion of this quest. You are tasked with retrieving a Fission Battery to repair the elevator (any Fission Battery will do). If you have a Fission Battery in your inventory, do not select a conversation topic to give it to Donovan and elect to repair the elevator yourself, you will still have a quest objective to give the battery to Donovan until you end the quest by debriefing Reilly. This does not seem to have any effect on the quest itself; just a quest objective that does not update properly.


 * Reilly will not pay you for locations you have already discovered until you either leave the compound. Speaking to her immediately after getting the Geomapper Module gets a response to the effect of "we already know about all of those locations". Since she will pay you for all of the locations on your map, you can complete this quest at any time, depending upon your need for caps.
