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.

A while ago, Allistair Tenpenny hired five mercenaries — Mister Crowley, Tara, Dave (of the Republic of Dave), 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 Mr. Crowley's original story will provide 7 (relatively) easy speech challenges with the named ghoul citizens in Underworld, giving you 10% 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 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.

Dukov
You can pay, persuade, or kill Dukov for his key. Cherry, one of Dukov's "party girls", can be persuaded to retrieve the key for you if you agree to escort her to Rivet City. You will also be given the option of "dueling" Dukov in a battle to the death, which should be fairly easy seeing as Dukov is armed solely with a sawed-off shotgun and lacks any armor. You can also obtain the key by pickpocketing Dukov, or, if you are a girl, you can talk it out of him with the Black Widow perk. Male characters with the Lady Killer perk can persuade Fantasia to lift the key from Dukov as well.

Strayer
The original Strayer is dead, but luckily his son, Ted Strayer, is alive and 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 either persuade him to give it to you, threaten him (Strength 6+ or Toughness perk), pay him (25 caps), kill him, or pickpocket him. If you choose to kill him outright, the guards may attack you. As an alternative, you can offer him Psycho, and he will overdose, allowing you to claim his key afterward.

Dave
To get Dave's key you can kill him, pickpocket him, or persuade him — just don't mention that Mister Crowley would like you to kill him. Go with the Wasteland Ambassador Route, which needs very little Speech skill, to get the key. If you do mention that Mister Crowley would like you to kill him, you can still gain the key with multiple Speech successes.


 * ''The easiest and best way to get Dave's key is just take a stealth boy and pickpocket him...Or just nuke him. Unless you care about your karma.

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 simply enter the CO's Quarters, travel down to the Basement door, and make your way through Fort Constantine. 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. The player is well rewarded upon gaining access, as these rooms contain a great deal of Small Guns ammo and weapons.

Choices
Now you have a few choices, you can
 * Go to Tenpenny Towers 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.

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.

Once you have collected the T-51b Power Armor for yourself, the quest will have been counted as completed and Mister Crowley will no longer be waiting for you back at the Underworld. Actually if you collect all keys, take the armor from the fort and then return to him, he will not have any dialogue options except floating speech, that you did rob him for his right-earned reward or something.

(NOTE: This is a glitch associated with this quest. Please see the talk page for more.)

The Most Profitable Way is to:

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.

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)
 * 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.

Getting the T-51b Power Armor
First off you have to get the keys, then reach the fort, which is on the northern edge of the map, east of Raven Rock. If you travel from Raven Rock, be prepared to fight Enclave Troops, Yao Guai and some treacherous terrain. Closer to the fort you encounter some Brotherhood of Steel Outcasts fighting Protectrons and Mister Gutsys. Go to the small house "The CQ Quarters" and head downstairs. In the basement you will find a dead Wastelander by an open safe. Next to the Wastelander is a Stealth Boy on top of a Chinese Army: Special Ops Training Manual. In the safe are some bottlecaps, a 10mm Pistol with ammo, the Big Guns Bobblehead, and the Fort Constantine launch codes. The door by the safe requires Strayer's key, and allows you access to the Launch Control Bunker. Continue down picking up ammo and other supplies along the way. In bomb storage you'll find Tara's body, on the opposite of the two Very Hard locked doors. Go to the nearby door open it with your key and pick up the Fat Man inside. Now disable the stasis field and you have your armor.


 * Prior to reaching the door to Bomb Storage, there will be a locked (average) launch control terminal. If you have the ICBM launch codes from the Bobblehead safe, or if you hack the terminal, you are given the option to launch an ICBM.  Choosing "Launch ICBM" causes some commotion in the room for a few seconds, but no real harm is done.  The doors will shut (they can be reopened), red lights will flash, the ground will shake, and some alarms will sound. Once everything is quiet again, check the terminal to learn that the ICBM failed to launch. This is an easter egg.
 * ''Next to the Computer is a copy of Duck and Cover! Watch the equipment on the north wall of the room if you decide to launch.  Also note the Big Book of Science sitting on a desk in the launch terminal room's NE corner.  Fun times.

If you give Mister Crowley all 3 of the keys, he will run to Fort Constantine. Later (give him at least two days) he MAY return with all 3 keys and the T-51b Power Armor, along with some other odds and ends, but only if he survives the trip out into the wasteland. This makes it so you don't even have to travel to Fort Constantine if you don't want to. So if you happen to have the Mister Sandman perk you can kill him without attracting any attention from the rest of Underworld. Now you have your armor and the keys! An alternative, and fun, way to kill him is to use a stealth boy and place a live grenade on him after he's retrieved the armor. Watch him blow up! Then take his stuff. The only risk is that when most NPCs venture out into the wasteland, they don't survive random encounters with the wildlife, so if he is killed on his way to Fort Constantine, then you've lost the keys and the armor. To prevent this you can go with him and protect him.

After you have gathered the keys you can go to the Fort and open all the doors. Don't get the power armor but instead return to Mister Crowley to get the reward to for the keys. Now travel back to the fort and grab the armor. Best of both worlds! However, upon discovering your theft Mister Crowley may turn hostile and hunt you down with his middle finger and a Scoped .44 Magnum.

Bugs

 * 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.


 * The Bloody Mess perk will frequently cause headshots to not count as such, as other limbs will be blown off as well. To prevent this, save before each headshot and reload if you sever additional limbs.


 * 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).
 * ''None of Crowley's conversation options will appear except the one that reports Tenpenny's death. If this happens, to actually accept the quest, you have to talk to Crowley a second time.


 * If you kill Dave, Ted Strayer, or Dukov and their body disappears before you nab their key, you can no longer complete the quest. If this happens, and you are on the PC version of the game, you can bring up console (~) and type:
 * player.additem 0002BF5A 1 to receive Dave's Special Key.
 * player.additem 0002B8DA 1 to receive Ted Strayer's Special Key.
 * player.additem 0002B8DB 1 to receive Dukov's Special Key.


 * 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, after accepting this quest, the game immediately reports that Allistair Tenpenny has been killed (and you did not kill him, obviously), one of the following things might have happened:
 * Allistair Tenpenny bugged out and fell over his balcony.
 * Allistair had been killed by somebody/something else. If you allowed the Ghouls to take over Tenpenny Tower, this might be why.
 * There was a script error and Allistair Tenpenny was teleported elsewhere and died.
 * There was a script error and the script instantly killed him.


 * If you give Mr. Crowley two of the keys, pickpocket those two off of him, and then give him all three keys in one go, he still acts as if you have another key to collect. The only known way to resolve this is by pickpocketing the keys and getting the Armor yourself to end the quest.


 * 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.
