Canyon City ( mission ) Canyon City is the sixteenth mission in " " . Walkthrough . During this mission , the Warrior will need to destroy six power nodes , with a catch involved where each node automatically repairs itself . So in order to complete the mission , the Warrior will need to plant explosives at each node to detonate them simultaneously . The Warrior can either bring their own explosives or can use the remote detonator trap s and detonator found during the mission and set them all to the same frequency . All the nodes are ordered and numbered in the same order they are shown on the map . Node One . The Warrior will begin at an intersection on the road , and will need to head to the right . There will be a significant amount of humanoid robot s and security robot s here to deal with . Among the corpses and a workbench , the Warrior can find the remote detonator traps and a detonator , along with a PPK12 Gauss pistol . From here , the Warrior will need to head through a door on the wall next to the workbench . In this area there will be several scurry robot s . Once they are dealt with , the first power node is in the small building to the right . Set the detonator trap and move on to the next node . There is an entrance to a tunnel here which will take the Warrior to a switch , and behind the entrenched humanoid robot s guarding the entrance to the building that houses the fifth and sixth power nodes . The entrance is located between the wall and the production line . Node Two . Head across the lot until the Warrior can see a platform with two ladders on it , leading over the wall and into the street . From here the Warrior will likely be spotted by a several hover robot s on the road . Now climb down the ladder and head across the street to a door in the wall . There will be two humanoid robots in the trench and another next to the door behind the sandbags . Continue heading south along the fence around the lot node two is located in . When the Warrior nears the street , there will be a second trench with more humanoid robots . Turn the corner and go through the opening in the fence into the lot . Inside the building a couple scurry robots near the node and a large metal door , repeatedly opening and closing . Behind this door is a pair of auto - cannon s . Once the charge is set , leave to the next node . Node Three . Head back out to the road next to the trench and follow it until the Warrior can see a white sidewalk . Follow this sidewalk to a black building with a large hole in the side of it and graffiti on the side . Inside is the third node , which is , strangely enough , completely unguarded . Node Four . Now leave the building and follow along the bottom side of it between the building and a fence until the Warrior gets to a small gate . Go through the gate and onto the road . Here the Warrior will see a Nuka - Cola plant and a ladder leading below ground . Ignore the ladder for now , as the Warrior will have to come back to it after the this node . Enter the building either through the door or the loading bay , either way the Warrior will be met by two security robots . Other than them the only thing here is the node . Node Five . Now head back out to the previously mentioned ladder . Climb down and the Warrior will immediately encounter a loadlifter robot . Now , continue down the tunnel to the right until the Warrior gets to a small room . Once the Warrior opens the door , a rocket - launching auto - cannon will open fire . Once this is taken care of , the Warrior can check the remains to find over 100 rockets . Now go up the staircase at the top room . Here will be a locked door that requires an extremely low amount of lockpick skill ( under 15 ) . If the Warrior can not get past the locked door , they will have to backtrack and go through the front entrance guarded by humanoid robots and auto - cannons . Once the Warrior goes through the locked door , they will be charged by a tank track robot . As long as the Warrior moves before it is able to fully spin up its weapon , it won ' t actually be able to make any direct hits , so continuously move and shoot until it goes down . If the Warrior goes through the first door on the right , they will encounter two scurry robot s and a humanoid robot with a sunbeam Gatling laser , and in the next room there is a pacification robot . The room on the left side down the hall will contain the node and three security robots . Node Six . Go through the door across the hall and up the stairs . From here the Warrior can either go through the door on the left or the door on the bottom . The door on the left has three security robots , but the door on the bottom puts the Warrior right in front of two humanoid robots , one of which has a Vindicator minigun . Once through here the Warrior can enter the final room with the node . Several scurry robots will be waiting . Set the final charge and move to a safe distance where the Warrior can safely detonate the explosives . Optional objective . In the final area the sixth node is located where there are three terminals that can be used to hear transmissions about Vault 0 . Listening to these is the secondary objective .
