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.

Make your way to the hospital and fight/sneak past the Super Mutants and Centaurs there (you can also find a good deal of supplies such as Stimpacks scattered around. After you reach the hotel via the downed radio tower, start making your way to the top of the hotel throught the stairs by whatever means necessary. However be warned that there are some traps scattered around the area. Be especially weary of Grenade Bouquets, these are 3 frags suspended above ground by rope and which are activated by a trip wire. Stealth based characters may find the hotel to be quite easy to penetrate. The long, dark hallways provide many stealthy sniping opportunities, and the Super Mutants' lack of Perception makes them easy to sneak up on. You'll Eventually reach Theo's body on a set of stairs, he won't be in very good condition, but his box of ammo will be fine. Open the box and take all it's contents, then continue your journey to the roof.

When you first meet Butcher on the roof, he'll tell you how his team has become desperate and that they need to make their way back down through the elevator, which is broken and needs a Fission Battery as a source of power. Now is your chance to give all the members of the team the ammo you found. You're job will then be to find a Fission Battery so the Rangers can make their escape. The nearest Fission Battery will be on a destroyed Protectron in the Restaurant that you just came out of (alternatively you can use any fission batteries you already have). 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 likely no match for the waiting Super Mutants (it's also a good idea to save before entering the elevator incase you wish to make sure all rangers make it back).

After your fight with the mutants is over and the rangers make their way outside, either follow them on their hike back to base, or fast travel to the base (or anywhere near the base if you have yet to discover the base itself) to finish the quest and claim your reward.

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.


 * If you've completed the Galaxy News Radio portion of the main quest and you used the back door of the station, you've already discovered Dupont Circle Station. There is an entrance there to the Dry Sewers, which lead into Our Lady of Hope Hospital.


 * 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 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 technically 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. (This assumes the ground floor is the same as the 1st floor, which is not the case everywhere in the world.)

Theo's body and ammo box is at the very south west stairwell of Statesman Hotel Mid-Level.

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.


 * Easiest way to the compound from the underground tunnel near Rivet City, enter Anacostia Crossing DONT go down, just straight across the ticket booth on the right side, jump over the sandbags down the ramp, just follow it and go to Seward Square exit.

Rewards
The quest rewards for this are either a suit of Ranger Body Armor (which can be repaired using any combat armor) 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 may not pay you for locations you have already discovered until you leave the compound and return. 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. Note: Got paid retroactively for all discovered map markers by engaging Reilly in another conversation right after ending the quest. (Xbox360 version)


 * In almost all of the hotel some of the Super Mutants (the ones that Reilly's Rangers had killed beforehand) are suspended in mid air by the waist, but all their limbs can be shot off (if they aren't already gone). This bug does not affect any part of the quest, and it has happened to more than one person.


 * The fallen mutants on the rooftop will have disappeared if the site is revisited, and a new spawn may occur. If taking the elevator to the roof, be prepared.


 * There have been bugs reported regarding how the quest is started. These involve not activating the quest though the radio signal or Reilly and may result in glitched endings, dead Rangers, or even making the Rangers hostile.


 * If you loot Donovan's Wrench off his dead body after he has repaired the elevator, there is no way to drop it (even if you do finish the quest). The game still thinks you need the item to fix the elevator yourself because Donovan died.


 * On PS3 when you enter the Riellys Rangers HQ whenever you talk to someone the dialouge will go extremly fast as if you are tapping X repeatidly. not sure about other version or if there is any fixs.
