You Gotta Shoot ' Em in the Head You Gotta Shoot ' Em in the Head is a side quest in " Fallout 3 " . It is also an Xbox 360 / PC achievement and a PlayStation 3 Trophy . Background . Allistair Tenpenny once hired five mercenaries : Mister Crowley , Tara , Dave , Dukov , and Jeff Strayer to find a rare weapon in Fort Constantine . In order to get a bigger share of the reward , Dukov trapped Mister Crowley ( a ghoul ) in a room with feral ghoul s . Crowley , who survived despite what everyone else believed , is now a resident of Underworld . Tara died in Fort Constantine and the three remaining mercenaries escaped and completed the mission . Detailed walkthrough . Starting the quest . Talk to Mister Crowley in the Ninth Circle or at Carol ' s Place in Underworld , but do not insult him when you first speak to him or he will not give you the quest . He gives you the task of 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 ) . 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 player a sniper rifle and five . 308 caliber rounds . Crowley offers 100 caps per death by headshot with the sniper rifle as payment . He says that " word will get around " if Tenpenny is killed , but he wants proof for the others : " something personal . . . like a key or a ring . " Crowley ' s true motives . Bribing or passing a speech check with any of the named non - player characters ( excluding Charon ) 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 ) . Other than the additional reward , the conditions of the quest do not change by learning this . Tenpenny ' s counter offer . Tell Allistair Tenpenny that Crowley sent you to kill him . After a successful speech test , Tenpenny will offer 300 caps if you agree to kill Crowley instead . Getting the keys . The keys can be obtained by Speech checks , pickpocketing , or by looting the key from the owner ' s corpse . They may be collected in any order and can be delivered to Crowley one at a time or all at once . Jeff Strayer is dead , but his son , Ted Strayer , is now in possession of his father ' s key . Ted lives in Rivet City . Dukov can be found at Dukov ' s Place . Dave can be found at The Republic of Dave . Obtaining the T - 51b power armor . Deliver the keys to Crowley . Kill Allistair Tenpenny and give Mister Crowley all three keys to collect your reward . He will then proceed to Fort Constantine to retrieve the armor . He will return to Underworld after a few days ( provided he did not get killed in the Wasteland ) . At this point you can kill him , which will turn all ghouls in Underworld hostile , or use reverse - pickpocketing in order to obtain the armor ( he will be wearing it ) . Retrieve the armor yourself . Proceed to Fort Constantine after obtaining the keys . Fort Constantine is located near the northern edge of the map , east - northeast of SatCom Array NW - 05a and southeast of the Train Tunnel if The Pitt is installed . When you arrive at the fort you will encounter some Brotherhood of Steel Outcasts fighting protectron s and Mister Gutsies . Go to the small house labeled " CO Quarters , " located downhill from Bomb Storage , 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 . You can also grab the " Bobblehead - Big Guns " from the safe while you ' re there . Continue down the stairs towards Bomb Storage ; you gain access here with Dukov ' s key . Inside the Bomb Storage facility , you will find Tara ' s body in front of a locked door . Open the door with Dave ' s key , proceed through the next door , disable the stasis field and take the T - 51b power armor and T - 51b power helmet . There is a warhead storage key on Tara ' s body . It unlocks a door that ' s just up a set of steps from here . This leads to a large room where nuclear warheads are stored , and the area is consequently highly radioactive . This key also opens either of the Very Hard locked doors topside that lead to the Bomb Storage facility . If you choose this solution , Mister Crowley can still be found in Carol ' s Place in the Underworld . He does not become hostile , but refuses to interact with the PC anymore , only repeating his line : " You stole what was rightfully mine . . . " Deliver the keys to Crowley and retrieve the armor yourself . Kill Allistair Tenpenny and give Mister Crowley all three keys to collect your reward , then follow Crowley on his long journey to Fort Constantine . He will require a lot of protection from enemies in the Wasteland or else he will die along the way . Crowley will become hostile upon reaching Fort Constantine , at which point you can kill him to retrieve the keys . If you don ' t want to follow Crowley , you can give him the keys and pickpocket them back , and then go to Fort Constantine . First open all the doors using the keys , but don ' t grab the armor , then give Crowley the keys to get the reward , then fast travel back and grab the armor . Additionally you can simply follow him into the lobby of the museum and kill him there ( you will not lose any Karma ) . Completing the quest . The quest is marked as completed and the achievement / trophy given under any of the following conditions :
