Rock Falls ( mission ) Rock Falls is the third mission in " " . Walkthrough . Insertion . Rock Falls is a mission that involves little beyond heavy combat ; bring some of the AK47 s and hunting rifle s you found in Freeport and a bunch of combat - centered recruits . You ' ll start off in a sheltered ruin , so get into a suitable position and get ready to start shooting . You ' ll want to immediately clear the ruins to the south ; there are three raiders milling about . From here , there are three ways into the compound ; the north side , through the fuel depot , the south side , through a small mine field , and through the main gate . South entrance . From the inhabited ruins , proceed east into even more ruins . There ' s a raider out front , patrolling near an alarm box . There are another two raiders near a burned out fireplace , asleep . Move towards the paved road , but watch out when you pass the overturned car ; there ' s a raider with an AK on an elevated platform , and there are three more raiders watching the road . A fat raider underneath the sniper ' s platform and a woman behind the sandbags up the road are both armed with AKs , and a guy with a pistol is hiding in the building with the sniper . From there , crawl under the orange scaffolding and you ' re in . North entrance . If you want to try the north entrance , sneak past the main gate ' s guards until you reach the fence with " madness " written on it in white . Just to your northeast will be four raiders around a campfire ; one has an AK , one has a pistol , one has an SMG , and one has a club . From there , head east . You ' ll need to get past a trench , which is guarded by two more raiders with AKs . Just over the trench is the fuel depot . There ' s a sniper tower out front , but no sniper , so you can grab it and take out the three raiders walking around the depot . You ' ll want to enter through the door in the north wall , which is locked . Main entrance . If you want to take the main entrance , then more power to you . There are seven raiders guarding the main gate ; four with SMGs , one with a pistol , and two with AKs . The gate itself is unlocked . Set sentry mode to ' aggressive ' . Assuming you went right in the front door , you ' ll be standing in a parking lot with two more AK raiders walking around . The building on the south end of the lot is a makeshift torture chamber . There ' s a raider with an AK in the waiting room , and three more raiders in the back room . One of those raiders is Daisy - May Gomer ; one of the four raider commanders marked for termination . Killing Daisy is worth 214 XP , and you can loot a key off of her to open a door later down the road . Don ' t forget to free Nanuk when the area is clear . On the north end of the lot is a building whose purpose isn ' t clear , but is inhabited by three more raiders . One has a spear , one an SMG , and the final is Luke Daniels , another raider commander . Killing Luke is worth 214 XP . North of the building is a clearing with a large pile of wood and rocks , with another three raiders standing round . To the northeast of Luke ' s building is the northern entrance , and a building containing Diesoon , a prisoner . Killing the four raiders ( three guarding the door , one patrolling with a dog ) and talking to Diesoon will earn you the mechanical arm , and complete one of the two objectives . Continue to clear the camp , and remember to talk to Diesoon when the rest of the raiders have died . It is also possible to kill him ( ironically for his name ) in order to obtain the Big Book of Science and take the arm from his body . That counts as fulfilling the objective as well . Extermination . From Diesoon ' s cell , the building immediately to the south is a workshop where another raider is chilling . From there , head south to find the medical station and the stables . There are three raiders hanging around in the open , and a fourth patrolling the stables . Past the stables is the south entrance and mine field ; watch the brahmin to make sure that they don ' t detonate a mine near you . Inside the med building is Bo Duffy , who ' s armed with a bunch of grenades but no real Throwing skill . Shoot him from outside , as he ' s more likely to hit the wall close to him . Killing Bo is worth another 214 XP . Through the mine field , you ' ll find another locked gate . The switch to open the gate is in a locked building , which can be unlocked using Daisy ' s key . There are two raiders armed with AKs on the tops of the walls , and another three guarding the upper entrance to the building . The lower entrance is locked , and needs a really high Lockpick skill to pick . The top floor of the building is inhabited by three men with Scorpios , and the bottom is home to Jesse Gomer and his personal guards . Killing Jesse is worth another 214 XP , and finishes the mission . Killing all four raider commanders is worth a bonus 600 XP . Make sure to go back and tell Nanuk and Diesoon to run , then head to the exit grid .
