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.

Background
Allistair Tenpenny once hired five mercenaries--Mister Crowley, Tara, Dave, Jeff Strayer and Dukov--to find a rare gun in Fort Constantine. In order to increase his share of the reward, Dukov trapped Mister Crowley (a ghoul) in a room with feral ghouls. Crowley survived his imprisonment and, when met by the PC, is a resident of Underworld. Tara died in Fort Constantine. The three remaining men finished the mission.

Starting the Quest
Talk to Mister Crowley in the Ninth Circle in Underworld. He gives you the task of finding and killing Dave (at the Republic of Dave), Jeff Strayer (in Rivet City), Dukov (at Dukov's Place), and Allistair Tenpenny (at Tenpenny Tower). He says they are ghoul-haters, and he wants them each killed with a shot to the head (as zombies are killed in fiction). For that purpose, he will give the PC a Sniper Rifle and five .308 Caliber Rounds. Crowley offers 100 caps per death by headshot as payment. He says that "word will get around" if Tenpenny is killed, but he wants proof for the others: "something personal... a key or something."
 * Crowley will only pay 25 caps for any killing method other than a head shot.

Something's Fishy
Bribing or passing a speech check with any of the named NPCs in Underworld--Ahzrukhal, Carol, Doctor Barrows, Winthrop, Patchwork, Tulip, or Quinn--will raise doubts about the targets' bigotry. Under questioning, Crowley will admit that he actually wants a special key from each target except Tenpenny. He still wants Tenpenny killed with a shot to the head. Instead of 100 caps per headshot, he will sweeten the deal by offering 100 caps up front plus an additional 100 caps for each key.

Mister Crowley's objective is the suit of T-51b Power Armor still stored at Fort Constantine. You can learn about Fort Constantine and the Power Armor from Crowley (with a speech check).


 * Admitting to Crowley that a key was obtained without killing the target lowers the reward to 25 caps. Lying about the method and receiving 100 caps is possible with a speech check.
 * Learning about Crowley's true intentions is not necessary to complete the quest.

Getting the Keys
The keys may be collected in any order. They may be delivered to Crowley one at a time or all at once.

Three of the keys can be obtained by pickpocketing or by looting the key from the owner's corpse. Tara's key can be found on her corpse.

Dukov

Dukov can be found at Dukov's Place.
 * Dukov can be paid for his key.
 * The Black Widow perk can be used to convince him to give up the key.
 * Male characters with the Lady Killer perk can persuade Fantasia to get the key.
 * Cherry will retrieve the key if the player accepts her quest.
 * With a successful speech check, Dukov can be intimidated into giving up the key.

Strayer

Jeff Strayer is dead, but his son, Ted Strayer, is now in possession of his father's key. Ted lives in Rivet City.
 * Ted can be paid for his key.
 * He can be convinced with a speech check.
 * He can be threatened (Strength 6+ or Toughness perk).

Dave

Dave can be found at The Republic of Dave.
 * With a speech success, Dave will accept the player as a "Wasteland Ambassador" and present his key as a gift.

Tara

The final key is located on Tara's corpse, in Fort Constantine. Tara's key is not necessary for completing the Crowley sections of the quest. It is necessary for getting to the Power Armor.

Tenpenny's Offer
Tell Allistair Tenpenny that Crowley sent you to kill him. Tenpenny will offer 100 caps if you agree to kill Crowley instead.
 * Tenpenny pays the 100 caps up front, so it is possible to double-cross him and just pocket the caps.
 * Killing Crowley for Tenpenny ends the quest.

Getting the T-51b Power Armor


Skip Crowley and Go Straight for the Armor

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. Don't forget to grab the "Bobblehead- Big Guns" from the safe! 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. Simply picking up the armour will grant you the achievement (Xbox 360, PC &amp; PS3).

Let Crowley Collect the Armor

If you provide Mister Crowley with all three of the keys, he will then proceed to Fort Constantine to retrieve the armor. He will return to Underworld after a few days (providing he did not get killed in the Wasteland). At this point you can a) kill him using the Mister Sandman perk, b) mez him with the Mesmetron (causing him to frenzy and be killed), or c) use reverse-pickpocketing in order to obtain the armor (he will be wearing the armor). This way, you will get paid for completing the quest and will acquire the armor as well.
 * Crowley may get stuck in bomb storage, even if he had all the keys. You need 100% lockpick skill to open the door.
 * If he falls in the Wasteland, you can find him and acquire the keys and/or armor (depending on whether he is on his way back from or going to Fort Constantine).
 * Mezzing Crowley will cause him to become hostile, and your companions and other NPC's in the bar will kill him for you. This can be done in the middle of the The Ninth Circle with people in the room, nobody else becomes hostile to you. (confirmed PS3, PC with patch 1.5 and xbox 360 current patch)

Deliver the Keys to Crowley and Retrieve the Armor Yourself

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 for the keys. Now fast-travel back to Fort Constantine and grab the armor.
 * After doing this, Crowley may show up at any point in the game looking for you because you double crossed him.

Completing the Quest
The quest is marked as completed and the Achievement/Trophy given under any of the following conditions.
 * The PC delivers the keys from Dukov, Ted Strayer, and Dave to Mr. Crowley.
 * The PC acquires the Power Armor in Fort Constantine.
 * The PC kills Crowley after having been hired by Tenpenny.

Bugs

 * Pathing Issues, patched PC version. Mr. Crowley often gets "stuck" while traveling, particularly when swimming.
 * While doing option 3, Mr. Crowley may track you down at your Megaton house. He meets you outside and, whether or not you speak to him, acts friendly and enters your house as soon as you do. He stands there for about a week. When speaking with him he acts as if he's still in Underworld ("Good to see you," "Hey"). However, once he exits the house and you speak to him as he exits Megaton, he begins saying, "You took what was rightfully mine," without becoming hostile. He then disappears from the game. (Confirmed on Xbox 360)


 * 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 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.


 * If you killed Dave before starting the quest and giving the key to Mr Crowley then pickpocketing the key back from him, you will be unable to finish the quest as it says on your Quest Journal "Give Dave's key to Mr Crowley" and there are no speech options for that.


 * 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.


 * Even if you completed this quest in a non-violent way, Three Dog may report in his Galaxy News Radio Broadcasts that you did murder the Crowley's targets.


 * 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.


 * If you have Bloody Mess and/or the body's head explodes, it will not be registered as a head shot, and you will not be able to receive the full 100 caps for the kill. There is a small chance the body will not explode with the Bloody Mess perk, so it might take multiple attempts for it to register as a clean head shot. (confirmed on xbox 360,PC)


 * Taking the Winterized T-51b Power Armor from the vault in the Outcast Outpost (After successfully completing the Operation: Anchorage simulation) completes this quest in the same fashion as taking the normal T-51b Power Armor from Fort Constantine. However, Mister Crowley doesn't seem to forge a vendetta against you as he would with the latter, but when you speak to him in Underworld he will still comment that you stole what is rightfully his.


 * If you succeed in the speech challenge with Cherry to get her to steal the key from Dukov there is no facial animation and no voiced dialogue you can only read her response in text. Once her response is over you can hear the voiced dialogue again with her talking to Dukov and everything continues as normal.


 * If you try to follow Crowley until he gets to Fort Constantine, he will become hostile upon reaching the building. (This is either due to the fact that the Brotherhood Outcasts turn hostile or that your follower turns hostile .) (Only tested once with Charon)


 * If you have Broken Steel installed when giving the keys to Crowley you will not be able to follow him heading to Fort Constantine. As soon as he leaves underworld he disappears from the game. (confirmed PC, XBox 360) Update: You can usually fix this problem by waiting by the entrance to the Museum of History and skipping 2 in-game hours. Crowley should appear at the entrance. Talk to him and then leave the conversation. Crowley will then proceed on his mission to acquire the T-51 b Power Armor.
 * The quest will complete itself sometimes when switching to a different quest, granting the achievement and registering that you have killed people that you have never met, and in a reported 360 case taking all items from a container.
 * If you kill Tenpenny, then kill Mr. Crowley, you will not fail the quest. It will tell you to talk to Tenpenney, and then to talk to Crowley, making it impossible to finish the quest. (Confirmed on all consoles.)
 * In dialogue with Tenpenny, you may not have an option to say that you killed Crowley.
 * Tenpenny says he will pay you, but for some reason you do not get anything in your inventory.
 * Pip-Boy may not acknowledge you talked to Tenpenny, making it impossible to finish your quest.
 * Mister Crowley may never return to Underworld, and might be found just standing (wearing the T-51b PA) in the building labelled Bomb Storage, on a hill just to the north of the CO's quarters. This can be very frustrating for players who do not have 100 Lockpick skill, because, without the keys, the only way to enter the building is through a very hard locked door. If this happens, he will speak to the player as if they are in Underworld. (Xbox 360, unconfirmed)
 * It might happen that, if you have taken this quest but haven't finished it by the time you go to The Pitt, it completes itself upon finishing the DLC, just by picking up any item when back at the Capital Wasteland. There's a Youtube Video illustrating this glitch.
 * After getting the armor and leaving the bunker to the wasteland, the game freezes. (X-Box 360)
 * If it is your first time visiting the Republic of Dave after starting the quest, and have chosen the option to be led to Dave, if you run ahead of the girl to Dave and kill him no one else will become hostile but they will not give dialogue options to you. (UPDATE) The girl that lets you in has to say something to the others in the village. Then run ahead to kill Dave. (360 only, tested once)
