Who Dares Wins

 is a Fallout 3 quest and achievement that is added to the game in the Broken Steel downloadable content pack.

Enter the Presidential Metro
Entering the Presidential Sub Level from Utility, you will face several Mister Gutsys (or Brain Bot and Protectron, and some Sentry Bots. After navigating through the sub level, the Lone Wander encounters  M.A.R.Go.T  (Metro Authority Rapid Governmental Transit System), a semi-sentient A.I. whom the Lone Wander may talk to. Upon talking, M.A.R.Go.T will try to identify the Lone Wanderer, which can be bypassed through a speech check, or a high enough science skill to bypass security protocol. If the Lone Wander passes security checks, he is marked as 'friendly', and so the robots of the Presidential Metro will no longer attack. M.A.R.Go.T explains that there has been a breach in security in the Presidential Metro, caused by unidentified persons who have no internal body heat and are emitting lethal levels of radiation (which obviously are Feral Ghouls).

(Optional) Clear the security breach in the Presidential Metro
Completing this causes M.A.R.Go.T to turn the power back on, saving you from searching for the fuse.

Glitch: If you kill first all the Feral Ghouls and then speak with M.A.R.Go.T for the first time, she will say that the security breach has been controled but you still have to find the fuse from the Presidential Senit Unit and when you leave the Presidential Metro to Adams Air Force Base it will mark it as complete (360)

Locate the Exit to Adams Air Force Base
Upon entering the Presidential Metro, the Lone Wanderer is faced by several Feral Ghoul Reavers, and Glowing Ones. It is very useful at this point to have been marked 'friendly' by M.A.R.Go.T, as the Sentry Bots and RoboBrains are helpful in dispatching the Feral Ghoul Reavers, who can be tough to kill. After killing all the Feral Ghouls, proceed down the corridor, through the equipment room (be sure to pick up the Nuka-Cola Quantum in here), and down the next tunnel. If you kill the Feral Ghouls as you go, you will soon clear the security breach. At the end of the tunnel, on the left is a Metro train. You will have to replace fuses on the main power box. They can be found on the Presidential Metro Sential Unit. You will have to kill it if you haven't already. Climb into the front, and activate the Metro Console to reach the Adams Air Force Base end of the Presidential Metro. At the top of the stairs is a locked door (average) behind which is a terminal to shut down the turrets just round the corner. After removing the Enclave Soldiers by the turrets, proceed on to Adams Air Force Base.

Retrieve your orders and equipment from the Resupply Crate
At the top of the exit stairwell, look left. The resupply crate is just behind the small building, by the wall. Contained inside are your orders, and a Tesla Cannon. The orders explain that opening the resupply crate triggered a beacon, and that the Brotherhood are to commence an assault on receiving that beacon to cover your entry.

enter the small shack and hack the computer turning off the turrets and make your way throw to the air tower avoid the flamers along the way (to save ammo call in an air attack on the virtabirds) you will also have to hack 2 more computers to shut down the second and third set of turrets. Continue your way through the Base untl you arrive to a field with hangars to you right and left, the first one to your left has 4 Deathclaw pens whre you may find 2 hostile Deathclaws inside their respective pens, you cannot turn them friendly with the Deathclaw Control Scrabmler, but in one of the other hangars you may find one that you can turn friendly

Find the Access Terminal to lower the ramp on the Mobile Platform
To Find the Access Terminal is at the top of the flight control tower, at the other end of the base. When you go through a destroyed hangar and enter to a large field in front of you is a building with a radar on it, the tower control biulding is to the left once you exit the destroyed hangar. There are stairs on the west side of the control tower building, use these to climb to the roof and head towards the tower, there will be a door that will allow you to enter the control tower. You can alternatively enter the building from the ground floor, avoiding the turrets on the roof. Once inside use the stairs to go to the very top of the tower and use the the access terminal to lower the ramp, granting you access to the Enclave Mobile Base.

Enter the Enclave Mobile Platform
Exiting the flight control tower, head down the stairs and take a left, heading through what was previously an Enclave Repulsion Field. See that big thing up ahead? HINT: the one with the HUGE tower and a radar disk in the top :), That's the Enclave Mobile Base. There is a small ramp leading up to the door, so head up there.

Destroy the Enclave Mobile Platform with an Orbital Strike
The first thing you come across is another Enclave Repulsion Field. Using the terminal to the right, you can deactivate it (Science 80), set a timed charge (Explosives 50), or smash the control panel. Turning left and heading into the repair bay yields plenty of ammunition, as well as an encounter with Stiggs, who fixes the robots. Talking with him gives some great information:
 * The floor above is the Deathclaw research facility, so there may be one or two left.
 * There are only a few Enclave aboard compared to the usual amounts.
 * The facility is patrolled by Robots, who are all controlled through a mainframe, located on the floor above, in the middle.
 * To reach the Satellite Tower, you have to reach the Central Control Area, then to the launch platform. After the platform, you'll probably have to fight a lot of Enclave to reach the tower.

Heading up the ladder at the back brings you to the Deathclaw Research facility. Heading straight through the door ahead,and looking right and then round the corner to the left a little is a Deathclaw. If you got the Deathclaw Control Scrambler then release him, and let him wander, killing for you. Upstairs you can find the Slo-Burn Flamer. From entering, going upstairs to the front-left corner you will find the medical bay, and to the right, access to the mainframe. Hacking the mainframe requires 75 Science (Hard). The terminal allows you to shut down the robots, scramble the targeting parameters, or (using the Robotic Experts perk) target the Enclave. A terminal across from the mainframe allows you to unlock interior doors, exterior doors, and the armory, where you can find an alien blaster in one crate (locked hard) with some power cells. Head towards the launch pad, using the ladder at of the mainframe room.

If you were able to set the Enclave as targets at the mainframe, then be happy! There are plenty of turrets and Sentry Bots up here that pretty much take care of the Enclave for you. Head to the Satellite Tower. Once inside, head to the top, to the terminal. Hit 'fire Payload', then chose your target:
 * Preset Target 01: Citadel
 * Preset Target 02: Project Purity
 * Preset Target 03: Megaton
 * Preset Target 04: Rivet City Carrier
 * Preset Target 05: Adams AFB Platform

Note only two of the targets can be fired upon: Adams AFB Platform, or the Citadel. Head through the door at the top back out to Adams Air Force Base, where Sentinel Lyons shows up in a hijacked Vertibird to get you out. Hop on, and away you go!

If you chose the Citadel: You are rewarded with negative karma, and on the flight back the pilots seem to think the Vertibird is malfunctioning when the Citadel won't respond to radio. Upon landing and seeing the smouldering ruins, they quickly pick up that it was you, and attempt to kill you, deeming you a traitor.

If you chose Adams AFB Platform: You are rewarded with positive karma, and the Vertibird lands a little off Adams AFB to allow you to watch the missiles strike. After hopping back on the Vertibird, you are taken to the Citadel, where Elder Lyons is waiting with a heart-warming speech of thanks.
