The Guns of Anchorage

 is a Fallout 3 quest that is added to the game by the Operation: Anchorage downloadable content pack.

Objectives and walkthrough
The aim of the The Guns Of Anchorage is to knock out a set of four guns, big guns to say the least.

After finishing the quest Aiding the Outcasts you are thrown into the simulation of Operation: Anchorage, to aid the Brotherhood Outcast in opening the door to the armoury.

You Start off on a mountain with Sergeant Montgomery in your Face, He explains to you your objective, to take out the guns, he hands you over some Charges, a 10MM silenced pistol, A trench knife and the new winterized combat armour.

This is where the mission starts. you head off over the hill to fight your first Chinese soldier, who should be very easy to kill. You head over the pipes, and into a cavern. Inside the cavern there is a small firefight occurring, and a Gauss rifle drops from the ceiling.

After that you head out of the cavern and head towards the Artillery lookout post, which has two bunkers and one big Chinese flag. Take out the guards and make your way into the building. Once into the building, find the warehouse where Montgomery mentions chimera tanks, fight through the guards and into another warehouse where you first encounter 'The Dragoons'. There are two of them, so quickly dispose of them and head to the guns. Once out of the outpost you'll be on a mountain top where the guns are firing, head up to the first one (each gun is guarded by 2-3 soldiers) and plant the first charge. You need to be a fair distance away from it as it is a HUGE EXPLOSION, then repeat the process on the other three, once this is complete you have finished the Guns of Anchorage.

NOTE: none of your weapons from the wasteland will be with you.
