You Gotta Shoot 'Em in the Head

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

Awhile 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 (from the Republic of Dave), Ted Strayer (in Rivet City), Dukov, and Allistair Tenpenny (in Tenpenny Tower). He asks you to do this because he says they are Ghoul bigots. 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, 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. Afterward learning from the other Ghouls that there's more to the story, chat with Mister Crowley again and he will tell you that what he really wants is the keys each person has. Instead of 100 caps for each headshot, he will sweeten the deal by giving you 100 caps up front and will give you 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 5 (relatively) easy speech challenge 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.

There's a glitch in Mister Crowley's speech where you can get the 25/100 caps for killing Tenpenny if you kill Tenpenny before you get the quest. All of Crowley's conversation options don't appear except the one that report's Tenpenny's death. If this happens, to actually accept the quest, you have to talk to Crowley a second time.

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 persuade Cherry to get the key for you and take her to Rivet City you will get positive karma. However, if you kill Dukov after having already escorted Cherry earlier, she will then show up as a hostile fleeing target in Rivet City and any companion you have in your party will kill her. You can also just pickpocket it. Or, if you are a girl, you can talk Dukov out of his key without paying for it with the Black Widow perk. Male characters with the Lady Killer perk can persuade Fantasia to lift the key from Dukov as well.

Strayer
Strayer's son, Ted Strayer in Rivet City, is now in possession of his father's key, which you can either persuade him to give it to you, threaten him, pay him, kill him, or pickpocket it. If your Strength is high enough to threaten him, he will give you everything in his inventory including his clothing. If you kill him, the guards will attack you.

Dave
To get Dave's key you can kill him, steal it or persuade him, just don't mention 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 Mister Crowley would like you to kill him, you can still gain the key with multiple Speech successes.

If in the election of Dave, Dave lost and you cannot find him to get his key you can find a piece of his corpse at the steps of the building next to the entrance to the sewers in Old Olney.

If you made Dave lose his election prior to taking on this quest, you will not be able to get the key via persuasion. He would either be dead or not talk to you.

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

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 will collect all keys and then take the armor from the fort and then return back to to him, he will have any dialogue options disabled 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.)

It seems the most profitable route that does encounter a glitch but does not break the quest is to:
 * Get the keys
 * Talk to Allistair Tenpenny and accept his offer of more money to kill Mister Crowley
 * Kill Mister Crowley
 * Return to Allistair Tenpenny for your reward, and ignore the glitch conversation options and map waypoints after you get it
 * Go to Fort Constantine and get the T-51b Power Armor, which properly ends the quest and grants you the quest experience

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 CO Quarters" and head downstairs. In the basement you will find caps and a Bobblehead go to the door, which will require Strayer's key. Continue down picking up ammo and other supplies along the way. Eventually you will reach an ICBM launch computer, you will need to launch it to open the door down the stairs. 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.


 * There is also a safe inside the first level of the basement complex that contains an ICBM launch code. Look around a level or so below that and you'll find the launch control terminal at which you are given the option to launch an ICBM.

Also, if you give Mister Crowley all 3 of the keys, he will run to Fort Constantine. Later 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! 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.

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.
