Fallout 4 exploits Add - on - specific exploits . Ahab ' s helm glitch . This requires you to have the Automatron add - on , a robot workbench , and the Sentry Ahab ' s helm looted from Ahab . It will not work with an " Ahab ' s Helm " created using the robot workbech . General advice and notes . This is not an exploit , but rather taking advantage of reoccurring radiant quests . Several quest givers accessible at lower levels such as Preston Garvey at Sanctuary Hills , or Knight Rhys and Scribe Haylen at the Cambridge Police Station , offer an unlimited number of quests to Radiant locations that should respawn when a new quest is started . Repeating Quartermastery or Cleansing the Commonwealth for the Brotherhood of Steel will provide a steady supply of XP from killing enemies and completing quests , as well as loot and ammunition from respawning Radiant locations . Armor mods . You can use mods from lower tier armor for higher tier of the same type , such as crafting a deep - pocketed mod for standard combat armor and applying it on heavy combat armor without having the perk to craft it for Heavy . ( This goes for all armor types with " standard " , " sturdy " and " heavy " versions - raider , metal , leather , combat - and is likely by design , rather than an exploit per se . ) Free Fat Man / mini nukes . You can easily gain an infinite amount of free Fat Mans and mini nukes . All you have to do is : ( If you plan on selling the Fat Mans , do so before you leave Goodneighbor , as she will restock caps every week . ) Menu - , HUD - , inventory - , and radio - related exploits . V . A . T . S . Auto - aim without using AP . Like in " Fallout 3 " , picking a target in V . A . T . S . auto - aims the crosshair reticule to that target . This can still be exploited to high degree in close quarters situations ( mole rat rush ) by : This is applicable in long - range engagements , but practicality varies . In close quarters , it is more consistent . Free ammunition exploit . This allows for you to have a full magazine of ammo which does not take away from your current supply . While this exploit is under effect , you can not reload your weapon and swapping to any other weapon or picking up ammo for the glitched weapon will automatically void the exploit . Duplicate weapons . This allows for duplication of any weapon . Build mods without having the perk or materials for it . This glitch can give a player slightly better weapons and armor mods than their perks or assets might allow for , giving them an early game edge straight out of the vault . When in the workbench mod menu list , any mod not highlighted and listed directly above or below one that can normally be constructed is capable of being built in its place . The process requires that adjacent mod not be built or in the players inventory . Select the mod that can be built while quickly press in the direction of the mod on the list that is normally not selectable . If timed correctly the materials window will appear but the selected line will have moved from the one with the known mod to the line one above or below it . Executing the build creates the mod from the new line at the cost of materials from the originally selected one . If the action is mistimed back out of the materials window without executing the build . Additionally , any mod slot where the first line allows for a mod to be removed and not replaced can be used to build whatever mod is on the next line down for free , if another mod in that list is already attached . Select the first line that removes the current mod while quickly pressing down , then execute if the menu focus switches the the second line . Since the original line has no material cost , the first mod below it is free . Settlement - related exploits . Duplicate materials . This allows for infinite raw materials at any settlement . Note : This works best with no junk in the workbench , as retrieving the material from storage is much faster when you don ' t have to scroll through a long list . If done correctly you should have had the scrap menu pop up and go away and be at the store menu . You should check and now have cloned resources . This is most effective with large quantities and can also be used as a caps glitch . Just trying to be helpful , I find it works better if after you release the scrap button just quickly press and hold the accept and store buttons at the same time . You should have both menus open for as long as you hold the buttons , the just release the select button , it should scrap and still have the option to store . let go of the scrap button and press the accept button . " Note : The " scrap " and " accept " actions trigger on button release , whereas the " store " action triggers on button press . Since you essentially want to trigger the " store " action while the " scrap " and " accept " actions are queued , the simplest way to do this is to hold ( but don ' t release ) " scrap " and " accept " with the fingers of one hand , and ready one finger of your other hand over the " store " button . Then , release " scrap " and " accept " in quick succession ( remember , it ' s the releasing of these buttons that triggers these actions - and they need to be released in the correct order ) while simultaneously tapping " store " with your other hand . Using this technique should make it significantly easier to pull off this trick consistently . The simple , more consistent way to do this resource duplicate process , and also makes it possible to be sure you do not destroy the item you are trying to get resources from is as follows : Drop item on the ground Go into workshop mode the same as above Hover over item Press and hold " scrap " ( square on ps4 ) button with one finger . Here is the tricky part , with another finger or hand , you need to press " store " ( circle on ps4 ) and hold it , at nearly the exact time you release square . While holding circle now you should notice that both accept menus are there . If you get them both go ahead and press accept on them both while still holding square . This will scrap the item , and return the original copy of it to storage . If you only get one menu or the other you can just cancel it without destroying the item or having to go take it back out of the workshop bench . Rug glitch for illegal placement of objects . When you ' re moving a carpet without using group - select , any objects on top of the carpet ( including other carpets ) move with it , but only the original carpet is checked for clipping . For example , you can stack two carpets end on end , then place a store on top of the second carpet in order to clip that store through an existing countertop in your settlement , or you could use it to place a bed halfway through a wall . This doesn ' t work on walls , floors , or any objects that snap onto things . " Note : Sometimes when removing the carpets , the objects may " jump " up or down . This might make it impossible to retrieve secondary carpets in addition to ruining the looks . " Settler weapon exploit . If you give a settler any weapon and provide at least one unit of ammo for the given weapon , the settler can use that weapon indefinitely without spending that ammo . This is particularly useful for the Minigun . Wires without limits . In order to connect two objects with wires while ignoring any barriers or distance limitations , do the following . " Things to note : " Money & experience . Succeed on every risky dialogue choice . To achieve a 100 % success rate on dialogue choices : This is a useful way to bypass the dialogue choice mini game . Trigger bright idea on quest completion . Idiot savant on second rank gives you 5 * XP on random actions , including quest completions ( basic go fetch quests 200XP + ) . Quicksave trick also works with this : Infinite XP . Notes This is best accomplished with Black - Rim Glasses ( CHR + 1 ) , Gray Knit Cap ( LCK + 1 ) , and Reginald ' s Suit ( CHR + 3 ) . ( Or any other CHR and LCK awarding apparel ) . Repeatable lockpicking . If you happen to find a locked safe right next to a terminal that can also control the lock on the safe , it is possible to pick the lock , use the terminal to lock the safe , then repeat the same process over and over . You will earn the XP for picking the lock every time you do it . This is most useful with a master lock , and even faster with the unbreakable lockpicks perk . This method cannot however be used to infinitely gain approval with Piper . Reapplied armor mod for XP . The Dense MOD for metal leg armor can be reapplied , giving additional XP , after selecting another leg MOD . The higher the the level of the metal armor the more XP is awarded . This can be repeated as long as raw materials are still available to craft with . The materials are consumed just as if a new Dense Metal Leg Armor MOD were created , however no additional copies of the MOD are added to your inventory . Effect exploits . Bleeding effects stack and do not extend . Meaning high ROF bleed weapons do increased damage . Companion character and settler clothing glitch / exploit . Companions and settlers can be reduced to wearing only underwear , even though the game UI tries to prevent it by hiding their currently worn piece of clothing from their inventory . Trade with a companion / settler . Give them a piece of over - clothing , a single piece that takes up armor slots such as a dress for the legs and torso or Radstag Outfit , and then press Y / Triangle / T to have them equip it . Their previous clothing is now listed in their inventory . Now give them a piece of armor that can ' t be worn over the clothing and press Y / Triangle / T to equip . This removes the clothing . Then un - equip the armor and they have nothing on . Location - specific exploits . Jamaica Plain . There are 49 steel , crystal , and fiber optics if all of the laser trip wires just prior to the room with the two Protectrons are disarmed , in the town hall basement . If you hit the red button at the end corridor you can start the trip wires over and can get an infinite amount of steel , crystal and fiber optics . This can be done even after destroying all turrets . A small amount of XP will be awarded for each as well . Gameplay exploits . Saugus Ironworks . Near the end of the Saugus Ironworks quest Out of the Fire to retrieve Jake and the Shishkabob , Slag tells Jake to kill the prisoner . If you successfully convince Jake to not harm the prisoner , Slag will wait for a few seconds before turning hostile . If you Save during this brief moment , when you reload , all of the Forged in the room will remain friendly until you fire at them . This affords you the opportunity to lay numerous mines at all of the enemies feet , which will not explode as long as they remain friendly . Then take a shot at one of them , they will all turn hostile , and all of the mines will blow , killing them all very easily . This exploit has only been tested at Saugus Ironworks , but may work in other similar situations if enemies wait for a while before turning hostile and you are able to save during that countdown . You may also do the same exploit during the dialogue when Jake asks you what he should do . Simply press your sideways movement key / button until the dialogue window disappears , then walk around and lay mines or do whatever preparation you like for the fight . Save prior to the beginning the fight and reload to make setup changes if you don ' t get the outcome you want . In this manner , you can easily save both the prisoner and Jake . Immediately after the fight , Jake may appear to be hostile , but speak to him and he should lower his weapon and admit his mistake in joining Slag ' s gang . Sentry Tower . An exploit used in order to keep an impossible to breach defense . Build a high stairway above your base and place several sentries . Then scrap all wood and the sentries will stay afloat , whenever the base is attacked the sentries will have a 360° view of the base . Traps . The exploit is used by saving then intentionally detonating / tripping traps . Then if you reload your save , the traps will be pre - tripped / detonated . ( bottle caps from bottle cap mines are not there . ) Free shield . Using the hold mechanic , you can hold an item and use it as a shield . This does not prevent you from using your weapon , making it an effective tool . First , drop an item ( preferably one with a large surface area ) on the ground . Now , hold the grab button ( a on Xbox One and x on PS4 ) until you are holding the item . You now have a shield that bullets can not pass through . Notes : Re - Speccing ( PC ) . This is not so much of an exploit as a method to change your build while staying somewhat honest . While this is still not included in the game , you do not gain any kind of unfair advantage except the hindsight . Robot workbench exploit . This glitch unlocks / creates MODS without having the necessary components for or perk level for . All you do is hold down a direction until it speed scrolls and immediately hit X on the one right after the locked mod while still scrolling ( note you do have to be able to create / Istall the mod right next to it ) it might take a couple tries but when you hit X on the one you were aiming for it will always highlight the one right before the one you hit X on . This trick works works both up an down as long as there is enough room for it to start speed scrolling . It can get a little tricky when the mod you want is near the end of the list . WARNING you might want to take off any mod you want to keep that it is replacing because it will turn into whatever mod you ' re installing . Patched exploits . The following exploits were patched in the versions specified below . If you find that any other exploits , that worked in a previous version , no longer work after a patch , please move them here . On consoles , it ' s possible to delete and reinstall the game to revert the game version back to v1 . 1 . 21 if you want to reproduce these . You may need to disconnect the console from the internet to prevent it from auto - updating to the latest version . It is unlikely that you will be able to load save files created with later versions of the game , so this will only work if you intend to start a new character . Saves created in v1 . 1 . 21 should load fine if you then update the game back to the latest version . Patch 1 . 2 . The following exploits no longer work as of patch 1 . 2 : - Patch 1 . 3 . The following exploits no longer work as of patch 1 . 3 : - Unlimited Items and XP after patch . To obtain unlimited items ( any item ) , you must have Dogmeat as a companion . For this instance , use copper . First go to a settlement of your choice , and begin the duplication process with Dogmeat . Once Dogmeat has picked up and dropped the copper , drop the copper you picked up . You should now have two different bars on the ground in front of you ; one that says the amount you had in your inventory , and the single bar that Dogmeat picked up . At this point save the game . Full save or quick save , it doesn ’ t matter . You then need to quit the game and reenter the game through continue , or load your most recent save . Once done , two bars with the original amount are on the ground . Pick up first the item Dogmeat dropped and then the original item . Once this is done , drop both again , go into workshop mode and scrap both items . After this is complete , when you go into your workbench , take out the item just duplicated and drop it . It will be consolidated into one item . Rinse and repeat until you reach your desired amount . ( Update - March 2016 ) With the above exploit , you don ' t have to quit the game after saving . After dogmeat drops the junk item then you drop yours , save the game then go into build mode and scrap the items . This also works with stacked junk items . Was tested multiple times on PS4 using base game , no patches . Once you have duplicated the copper to your desired amount , you will be able to build statues to increase your XP . ( Picket Fences issue # 3 magazine found in Saugus Ironworks ) Alternative Method ( Junk items only ) : For this example , you have twenty copper in your Junk inventory . You drop it , use Dogmeat to duplicate it . Drop all the copper in your Junk inventory " after " dogmeat has dropped his . You should see twenty copper on the original bar and twenty on Dogmeat ' s duplicate bar . ( If you dropped your copper from your inventory " before " Dogmeat does your copper bar and his may be reduced to one ) . At this point the above instructs to quick save , quit and load . You can actually scrap both in the workshop menu and it will show both as twenty and twenty as being scrapped . You should now have forty copper in your Workshop . You can extract the forty copper and rinse and repeat . Note : Not only does this method save time , but also ensures that the junk items are joined together and do not separate when dropped . If you have less than six items the game will not ask to drop all together , so just use Dogmeat to make more than six and then follow the above guide . Notes Weapon mod duplication . Buy a weapon modification from a vendor , such as " Triple barrel X + " and have an " accelerated barrel " for the minigun , and attach triple barrel X + then switch to accelerated barrel . Now constantly between the two barrels and you should be awarded a triple barrel or triple barrel x + every time you switch . Patch 1 . 4 . The following exploits no longer work as of patch 1 . 4 : - Crafting exploit for infinite experience . Every time the player crafts an item at a settlement , they earn experience , and the experience earned seems to depend on the overall value of consumed items used to craft the item . There is a method that can be used to create an infinite amount of crafting materials by purchasing one of the " shipment of xxx " dockets from a vendor . Therefore , any items crafted from said infinite material will yield the player an infinite amount of experience as long as they continue to farm the material , build an item crafted from the material , scrap all the items used to build the material ( since you can only place so many items in a settlement ) and repeat . First , the player must obtain a " shipment of xxx " docket from a vendor , of which types are available vary from vendor to vendor . For the purposes of this small guide , which I will explain as to the reasons why in the next section , I suggest the player use the shipment of copper docket from Arturo in Diamond City . They simply need to purchase one , however it is most efficient if the player was to use the wait feature to purchase as many dockets as the player is willing to collect . Once obtained , the player should take the docket to one of their settlements . This is a very important note : DO NOT PLACE THE SHIPPING DOCKET INTO THE WORKSHOPS INVENTORY UNTIL YOU ARE READY TO PERFORM THE EXPLOIT . If you do , the docket ( s ) will ( almost ) immediately be converted into its shipped material and the docket ( s ) will disappear , requiring you to load an old save or buy a new one . It is highly suggested that , for this reason , the player saves the game quite frequently every time they go to access their workshops inventory . The next thing they should do is make sure there is no inventory in the workshop , and that the only junk item in your inventory is / are the docket ( s ) . The next step is tricky , and it is advised that one saves before attempting it , and throughout save in tiers as to prevent you having to start all over : while in the workshops inventory , you are to press y ( or triangle on the PS4 version ) ( to store all junk items ) and IMMEDIATELY afterwards , press x ( or square in the PS4 version ) ( to take all ) . If done properly and quickly enough , the materials provided from the docket should be created , and your player will collect the " shipment of xxx " docket without it disappearing . This method can be repeated quite quickly in succession , simply by rapidly pressing yxx ( triangle , square , square , if played on the PS4 version ) over and over again to store all junk , immediately collect all junk items in the workshop , and then open the workshops inventory again . Doing this obviously benefits the player in a multitude of ways : they can use this to farm an infinite amount of a rare / valuable crafting material ( such as aluminum , copper , or adhesive ) collect an infinite amount of caps from vendors simply by selling the farmed materials , or farming a vary large amount of experience points in a fairly short period of time by simply crafting something which uses this duplicated material over and over again . It seems one of the best methods , if not the absolute best method , is to obtain the Picket Fences # 3 : Essential Upgrades ! magazine from Saugus Ironworks , as this allows for the crafting of copper statues . The very first statue , which features a baseball player , uses 10 copper and provides the player character anywhere between 25 - 35 experience ( based on the player ' s intelligence ) every time it is placed . By walking backwards and rapidly pressing A ( X in the PS4 version ) , the statues will be placed one after the next , netting the player several thousand experience points in just a few minutes . Exact gain of experience is difficult to determine , however trial of this exploit resulted in leveling up from level 35 to 100 within approximately 3 hours of gameplay . EDIT : With extensive testing of this exploit , one was able to level up from level 1 at the very start of the game to level 271 ( wherein all perks had been maxed out ) in less than 18 hours of gameplay . While 18 hours of doing one action seems arduous , it is significantly more efficient than leveling up by playing the game normally , which one can estimate to be around 300 + hours of gameplay , even with high modifiers to Intelligence throughout . Another Method , albeit slower , is to get specific Items and get to a Chem Workshop there you can for example craft Buffjet by pressing X and O on Playsation ( A and B on Xbox ) at the same time . If done correctly , the Crafting confirmation screen will appear , however it will be back at the crafting menu . If not done corrctly it will still be on the same page as before . This is also very easy to do as Buffout and Jet can be obtained in the beginning of the Game . Be reminded however that it will take longer . Patch 1 . 5 . The following exploits no longer work as of patch 1 . 5 : - Bypass approval cooldown timer . The Approval cooldown ( e . g . the time you need to wait after crafting a mod for Codsworth / Preston or picking a lock for Piper until they " like " it again ) can be reset by saving and reloading the game . This works exceptionally well with MacCready , who will gain affinity points regardless of what you steal . With just the items available in the Third Rail where you recruit him , you can get the Long Road Ahead quest before leaving the building . You can gain approval by stealing , quicksaving , reloading , and stealing another item ( vase , desk fan , etc ) . Hacking robots with weapon . If you have a weapon equipped and see a robot ( doesn ' t matter if its idle or actively attacking ) you can zoom in using the weapon and hack that robot from a pretty far distance .
