Cold Water ( mission ) Cold Water is the thirteenth or fourteenth mission in " " . Walkthrough . Ground floor . Your insertion point is on the ground level of the town , and the town is separated into multiple floors , or " tiers " . The ground level is almost all civilians , some of which you can barter and gamble with , but there isn ' t a whole lot of valuables for sale . Notable items are P94 plasma rifle ( sold by the auditor ) , a Big Book of Science , Guns and Bullets , Calico Liberty 100 , and some ammunition . Note that once you are ready to proceed up the stairs to the second floor there will be two hostiles waiting near the staircase behind some sandbags . Second floor . As soon as you enter the second floor , the room above you will have three hostiles that may spot you . There are also quite a few civilians on this floor mixed in with the hostiles . Since there is no power armor to obtain here , you can either go right ahead up the next staircase or stay and explore . There will be a few more hostiles but on either end of the floor there will be BOS crates with supplies which include an Avenger minigun and a Browning M2 . Also on this floor is Simon Dudley , in the bar , which is the room just south of the staircases . He activates a secondary objective ( see Optional Objectives below ) . Third floor . The third floor , like the second , still has no power armor and is a mix of hostiles and civilians . In one of the civilian rooms ( the one with the interior balcony looking into the second floor ) , Ma Baker offers for gambling a power fist . Also worth mentioning is a Cabinet on the very left side of the second floor appartments containing four acid grenade s and four incendiary grenade s . The most notable hostiles on this floor are guarding the staircase to the fourth floor . There are three of them behind sandbags , one with a rocket launcher and two with M60s , so be careful rounding the corner too fast . Fourth floor . The final floor , and the floor where all three of the power armor thieves reside . Once you get to the top of the stairs you should switch to your best weapon , as the first thief is nearby . Once you move in front of the doorway on the top right side you will be charged by several hostiles , one in power armor and wielding a flame thrower . Try to keep your distance from him and he won ' t be able to damage you at all . Also waiting to pop up is a guard standing outside behind a stack of sandbags to the south . Once the threats are dealt with , loot the first thief ' s corpse and take the broken power armor ( weighs 42 pounds ) and move on . If you go left into a bathroom that looks like it has never been cleaned there is a footlocker with a First Aid Book and a first aid kit , other than that , nothing of interest , so continue to the right where the hostiles came from earlier . The way this floor works you will be forced out onto the dirt balcony ( outside ) , but once there watch your step as it is covered with mines , which is indicated by the crates of mines and the corpse on the ground . If you stay at the very edge of the " cliff " side you won ' t activate any mines . Midway along the cliff you will see a doorway with " 666 " next to it . Ignore this door as it is trapped and you would have to walk through the minefield to get to it . Besides , you will need a key to open this door , and you don ' t have it yet . Once you pass this there will be two hostiles with machine - guns waiting behind sandbags . After this you will have access to a generator room , inside are several guards and the second power armor thief , so equip your best weapons . He will stay at the very rear of the room using a Browning M2 , so react accordingly depending on what you are using , but you will likely need to charge him . Once he is killed loot the broken power armor . Next to his corpse will be a power switch that you can use to turn off the lights if you wish , but it is unnecessary . Next there will be a short hallway and a small room , both with sandbags and a few hostiles . Then will be the final room . At the doorway to this room will be one hostile with a Ripper who may charge you ( better to deal with him outside the room ) . The layout of the room doesn ' t lend very well for cover , but if you go in prone at the doorway on the right instead of the left you can use the sandbags for cover . But as soon as you enter the room there will be a guard with a rocket launcher waiting for you . Once he is taken care of you can line up behind the sandbags . Now all that is left is the last thief and his two guards , all three of which will be wielding energy weapons . They all have very good range , so unless you also have very long range weapons you may need to charge forward to take care of them . If not , fire from the prone position . Once the last thief , Guldo Sciavo , is dead , loot the final piece of power armor . You can now head back to return the armor to the Auditor at the extraction point . Bugs . Simon Dudley tells you that he is giving you something as a reward for saving his sister , but he doesn ' t actually give you anything .
