You Gotta Shoot 'Em in the Head

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

(For some unknown reason if you get the T-15b power armor after getting this quest it counts as if you did it) A while ago, Allistair Tenpenny hired five mercenaries — Mister Crowley, Tara, Dave (of the Republic of Dave), Jeff Strayer (father of Ted Strayer in Rivet City) and Dukov. They were hired to find a rare gun for Allistair Tenpenny in Fort Constantine. It appears there was a bit of backstabbing done by Dukov to increase his share of Allistair Tenpenny's reward for the gun. Sometime during the mission Tara died and Mister Crowley (a Ghoul) was locked in a room with Feral Ghouls (who did not harm him). The three remaining men finished the mission with Dave and Strayer being very leery and cautious of Dukov.

Objectives and Walkthrough
Mister Crowley, a resident of Underworld, tasks you with finding and killing Dave (at the Republic of Dave), Ted Strayer (in Rivet City), Dukov (at Dukov's Place), and Allistair Tenpenny (at Tenpenny Tower) as he says they are Ghoul bigots and deserve it. He will give you a Sniper Rifle and 5 rounds for the job. You can check up on his story by talking to many of the named NPCs in Underworld, such as Ahzrukhal, Carol, Doctor Barrows, Winthrop, Patchwork, Tulip, or Quinn and passing a Speech check or in some cases simply paying them. These people will put the lie to Mister Crowley's reason for wanting the other mercs dead. After learning from the other Ghouls that there's more to the story, chat with Mister Crowley again and he will tell you what he really wants is the key each person has. Instead of 100 caps per headshot, he will sweeten the deal by giving you 100 caps up front plus an additional 100 caps for each key you bring him. However, he still wants you to kill Allistair Tenpenny. It appears that Mister Crowley's actual objective is the suit of T-51b Power Armor still stored at Fort Constantine, which he ostensibly observed while locked up with the Feral Ghouls.

Investigating Mister Crowley's original story will provide 7 (relatively) easy speech challenges with the named ghoul citizens in Underworld, giving you 14% of your goal toward the Silver-Tongued Devil achievement. This quest, combined with at least three other unrelated speech challenges, makes Underworld a good place to knock out the achievement. It is worth noting that the player does not need to complete all of the speech challenges to ask Mr. Crowley about his true intentions.

If you question Crowley about his intentions and then tell him you will keep the keys for yourself, he will turn hostile and so will the rest of the inhabitants of Underworld. If you leave and return, all inhabitants will return to a friendly state except Crowley, who will still try and shoot you on sight. Killing Crowley at this stage fails the quest.

If you tell Crowley that the keys were obtained without killing the target, he will only give you 25 caps instead of 100 caps as promised. However, with a high Speech skill, you can lie about killing the targets and get 100 bottle caps per key.

You can get 100 caps if you lie about killing the target when turning in keys. (confirmed Xbox 360)

Getting the Keys
Any of the keys -- with the exception of Tara's -- can be obtained through persuasion (usually a Speech check), pickpocketing, or looting the key from the owner's corpse. For specific strategies, see the entries below.

Dukov
You can pay Dukov to obtain his key. If you wish to kill him, one method is to push him next to the motorcycle in the main room on the bottom floor and shoot it until it explodes. You can also duel him to the death, which should be fairly easy, as he is armed solely with a 10mm SMG and lacks armor. Alternatively, the Black Widow perk can be used to convince him to give you his key, and male characters with the Lady Killer perk can persuade Fantasia to get the key for them. Cherry can also be persuaded to retrieve the key for you if you agree to escort her to Rivet City.

Strayer
Jeff Strayer is dead, but his son, Ted Strayer, is now in possession of his father's key. You'll find him in Rivet City, and although he had nothing to do with the original mission, he has some knowledge of the event. You can threaten him (Strength 6+ or Toughness perk), pass a speech check, or pay him (25 caps) to get the key. The use of a Stealth Boy will also allow you to get the key, as he has very low perception.

If you convinced Mister Lopez to guide Ted, he and Ted will wander the area near Vault 101. This area can spawn Raiders, Radscorpions and even Yao Guai and Deathclaws at higher levels, so it is recommended you do this before helping Mister Lopez. If not, you can reverse pickpocket equipment onto Ted and Lopez before they leave, or come prepared for a fight.Also very rarely a giant radscorpian and some dead ants will appear.

Dave
Through Speech successes, it is possible to convince Dave that you are a "Wasteland Ambassador," and he will give you his key: however, it may be to your advantage to avoid mentioning Mister Crowley if you choose to do so. If you help someone else win the Election for President of The Republic of Dave, Dave will abandon his republic. He will head west, to Old Olney, where he will most likely be killed by the large number of Deathclaws that have infested the town. You can also provoke Dave to attack you through speech, and he can then be killed without karma loss or retaliation by others.

Tara
The final key is located on Tara's corpse, which was "conveniently" left behind locked doors in Fort Constantine. Once you have the other three keys, you can enter the CO Quarters, travel down to the basement door, and make your way through the fort. Tara's corpse is located in front of a locked door requiring a Special Key, in a room that contains a Sentry Bot, two "Very Hard" terminals, and two "Very Hard" locked doors. You can either hack or lockpick to get inside these small storage rooms, which each contain a variety of weapons and ammo.

Choices
Now you have a few choices, you can
 * Go to Tenpenny Tower and speak with Allistair Tenpenny
 * You can either kill him, or accept his offer to kill Mister Crowley instead
 * Go to Fort Constantine and use the keys to get the T-51b Power Armor
 * Return the keys to Mister Crowley
 * Go to Fort Constantine and use the keys to open all doors, but don't take the T-51b Power Armor. After that go to Mister Crowley and give him the keys. Then go back to the fort and grab the armor.
 * After taking the armor Mister Crowley will search out the player, and attack you in any location.
 * Once at Fort Constantine Mister Crowley will become hostile to the player until he has the T-51b Power Armor.
 * Kill Mr. Crowley. Note: Killing him will provide no karma loss and will provide a finger (provided you have the Lawbringer perk).
 * Returning the keys or collecting the power armor both count as a successful conclusion to the quest. Of course, if Mister Crowley already has the keys or you just gave him the keys, you can steal them back or kill him for them.
 * If you're going to kill Mister Crowley anyway, you might want to warn Allistair Tenpenny that Mister Crowley wants him dead. Allistair Tenpenny will offer you 200 caps (300 caps with speech) to kill Mister Crowley instead.
 * If you have completed the Operation Anchorage simulation or have retrieved the armor for yourself, Mr. Crowley will tell you that you took what was rightfully his.

The Most Profitable Way is to:

Additionally, if you pickpocket each key back one by one after passing the speech challenge, you can open up the dialogue again and turn them in again. This will award you the standard 25 cap payout per key on top of the 100 caps you already received. You have to steal each key back before Mr. Crowley has them all in his possession or else the quest will be completed. Total reward: 600 caps, T-51b Power Armor, good karma (from killing Tenpenny)
 * Start the quest.
 * Talk to the people of the Underworld to learn more about Mister Crowley, and then have a little chat with him to receive the 100 additional caps.
 * Get the keys from Dave, Dukov, and Ted Strayer (there is no need to kill them).
 * Go to Tenpenny and tell him that you were sent by Crowley to kill him, then pass the speech challenge for a 300 cap reward, receiving 100 caps up front.
 * After you get your caps, blow Tenpenny's head off.
 * Return to Mister Crowley and tell him Tenpenny is dead. Get the 100 caps for killing him, and then end the discussion without mentioning anything about having the keys.
 * Talk to Mister Crowley again. Initially (if you did not kill the people who had the keys), you'll only have the option to tell the truth about how you got one person's key (receiving 25 caps), or say you have not gotten the keys yet. Choose the latter. In the next list of things to say, you'll have the option to lie about having killed the key's owner. Pass the speech challenge, getting 100 caps, and then close the discussion. Save the game, and repeat the same for the two other people whose keys you got.
 * Once that's done, the quest will be completed. However, you can still get the armor. All you have to do is steal the keys back from Mister Crowley (soon after you give them to him obviously, before he goes and gets the armor), and then just go get the armor yourself. Mister Crowley can then be found back at the Underworld, asking you (when you get close to him) if you've seen any keys, which he thinks he has lost. If you try to talk to him he'll claim that you "took what was rightfully mine, get lost."

OR (for those sadistic double-crossers)

Total Reward: 700 caps, Mr. Tenpenny's fancy suit, assorted firearms, and the T-51b Power Armor
 * Obtain Dave's, Dukov's, and Ted Strayer's keys by hook, crook, or gun.
 * Talk to Allistair Tenpenny and pass the speech challenge for 300 caps.
 * Persuade a ghoul in Underworld to tell you the truth about Mister Crowley
 * Turn in 2 keys for 200 caps via lying (save here, if you like to save between conversation attempts) **Note: This does not seem to work on the PS3 as you cannot lie about the keys unless you have killed Tenpenny. Also, if you have Charon with you and you decide to kill the marks leave him somewhere so he doesn't help. He will shoot at them also and you won't get credit for a headshot (even if you use vats to ensure a headshot).**
 * Ask about the truth to get the 100 cap bonus, then turn in the third key with the lie (Do not exit conversation, or you'll only get 25 caps for giving him the key) for the last 100 caps.
 * Kill Mister Crowley and loot all 3 keys. Kill him after he leaves and is out of sight of Willow (the guard), kill him in a shop where the only witnesses are nameless residents (and don't let any of them escape), or kill him, and everyone else in Underworld, if option 1 or 2 seem like too much trouble to stay friendly with the denizens of Underworld).
 * Go back to Tenpenny and get the rest of your pay (then kill him for a fancy suit and a shiny sniper rifle).
 * Collect the T-51b Power Armor to complete the quest.

Another Tip: If you are going to kill Mister Crowley, you first give the keys for the caps and then by using your Mesmetron you will be able to frenzy Mister Crowley (save before doing, because it will not always berserk him), and thus be able to kill him without any residents becoming hostile to you except Mister Crowley; the Underworld residents even help you killing him.

OR...If you have already completed Crowley's request for the keys, return to underworld later in the game, Crowley will be back in his place, wearing the T-51b armor, talk to him, and he will brag about it, then just kill him, and loot his body for the armor, and all the keys, if you want to explore fort Constantine on your own. This will not result in a Karma loss, or hostile underworld residents, because Crowley is considered an evil character, so you can loot him for a finger if you have the Lawbringer perk

You can also kill him in the middle of town with around 75 sneak, Chinese Stealth Armor/Stealthboy and a melee weapon. (This style of assassination works for any citizen you want to dispose of as melee weapons don't raise detection.)

Getting the T-51b Power Armor
There are three ways to obtain the T-51b Power Armor and T-51b Power Helmet. The first way is to retrieve the keys from Mr Crowley's targets and then travel to Fort Constantine to retrieve the armor personally, while the second way is to retrieve it by either killing Mr. Crowley after he retrieves the armor or pick-pocketing it from him. The third way is to unlock all of the doors at Fort Constantine after obtaining the keys but not taking the armor.

Option 1
Proceed to Fort Constantine after obtaining the keys. Fort Constantine is located near the northern edge of the map, east of Raven Rock. When you arrive at the fort you will encounter some Brotherhood of Steel Outcasts fighting Protectrons and Mister Gutsys. Go to the small house called the "The CO Quarters" and head downstairs. In the basement you will find a dead Wastelander by an open safe. The door by the safe requires Strayer's key, and allows you access to the Launch Control Bunker. Continue down to the bomb storage, where you will find Tara's body, on the opposite of the two Very Hard locked doors. Go to the nearby door and open it with your key and disable the stasis field to acquire the T-51b Power Armor and T-51b Power Helmet.

Option 2
If you provide Mister Crowley with all 3 of the keys, he will then proceed to Fort Constantine To retrieve the armor. He may return after a couple of days (providing he did not get killed in the Wasteland) to Underworld. At this point you can either kill him using Mister Sandman perk, mezzing him with the Mesmetron (causing him to frenzy and be killed) or by pickpocketing him in order to obtain the armor. This way you will get paid for completing the quest and will acquire the armor as well. NOTE: If he falls in the Wasteland, you can find him and acquire the keys and/or armor (depending on if he is on his way back from or going to Fort Constantine).

Option 3
After you have gathered the keys you can go to Fort Constantine and open all the doors. Do not get the power armor but instead return to Mister Crowley to get the reward to for the keys. Now fast-travel back to Fort Constantine and grab the armor. NOTE: After doing this, Crowley may show up at any point in the game looking for you because you double crossed him.

Bugs

 * If for some reason you kill or take a key from one of the targets before you get the quest, and then talk to Mister Crowley, he will act as if you have already accepted the quest, give you the caps and tell you to go for the next person on the list.


 * Taking Ted Strayer's Special Key before meeting Crowley and may result in being unable to begin the quest.


 * After accepting Allistair's offer and killing Mr. Crowley, Allistair may not have a speech option to finish the quest. If this happens, you can:
 * Repeatedly talk to Tenpenny and he will eventually recognize that Crowley is dead and give you your reward.
 * Take the T-51b Power Armor from Fort Constantine and complete the quest. If you do this, you will miss out on the reward for killing Crowley.


 * Killing Tenpenny before you accept this quest may cause Mr. Crowley to give you only 25 caps as a reward (even if you scored a headshot).


 * If you kill Dave, Ted Strayer, or Dukov and their body disappears before you nab their key, you can no longer complete the quest. However the keys can be obtained via the console commands. See Dave's Special Key, Dukov's Special Key and Ted Strayer's Special Key for the item codes.


 * Mr. Crowley may ask for a key you have already given him. If this happens, you will need to pickpocket Crowley to get the key back, and then give it to him again.


 * If you completed this quest in a non-violent way, a bug may occur that will cause Three Dog to report in his Galaxy News Radio Broadcasts that you DID murder the people that Mister Crowley wanted you to, despite not having done so.


 * Sometimes, when trying to leave Bomb Storage, your console will freeze. (This has happened to me 3 times on the 360 so far. That happened to me on the PC version I had to restart a previous save.)


 * After doing the quest, unlocking the doors before I gave Crowley the keys, then going back and getting the armor before him, I put the helmet in my wardrobe in my Tenpenny house. Charon is wearing the armor.  I slept and Crowley appeared in my room in Tenpenny.  Pretty amusing.  (Xbox 360)


 * A speech check allows you to get the location of Fort Constantine from Mister Crowley. You can use this check twice: once before completing the quest, and once after.


 * (ON PC version) After refusing to give keys, allowing Crowley to attack player and killing him, ALL residents (except for the three women business owners, doc, nurse and barber) became hostile and attacked, even Cerberus and Charon. Went back next day, no bodies, no other NPCs to interact with, just the six listed, with no hostility.
