Fallout 4 exploits

Weapon Mods
This exploit is very easy to perform and will save many resources when crafting. First, take any weapon with craft-able mods and go to a weapons workbench. Look for a mod you want to make, for example the MIRV launcher mod for the Fat Man. While hovering over the mod simultaneously press X and Circle(PS4) with the X being pressed slightly sooner so it confirms without backing out of the current mod list. If done right the screen should pop up the confirmation window for crafting but the box along the bottom of the screen will have gone back to showing all mods currently equipped for that weapon. Press the confirm button and the mod will be crafted and equipped to the weapon and you will receive experience for crafting.


 * To perform this exploit you will still need the required materials but they are not consumed during the process.
 * This will sometimes not work with mods such as Bayonet and rarely Scopes and no experience will be received when trying with ones that do not work.
 * Works with crafting mods for weapons/armor/power-armor and also works for crafting food items and chems.

Armor Mods
You can use Mods from lower tier Armor for higher tier of the same type. Like crafting a Deep-Pocketed Mod for normal Combat Armor and applying it on Heavy Combat Armor without having the perk to craft it for Heavy.

Changing building limit without console

 * 1.Drop weapons from inventory
 * 2.Enter building mode
 * 3."store" those dropped weapons to workbench from building mode (pc button TAB/Xbox One B button). Scrapping the weapon will also work in reducing the size if done from building mode
 * NOTE: This exploit has been re-tested (on Dec 9th, 2015) using an Xbox One patched to version 1.2, and it still working.

Menu-, HUD-, inventory-, and radio-related exploits

 * The game allows saving during npc dialogs which makes it easy to reload the game and retry any option which may influence caps, experience, etc. outcome when talking.

Succeed on every risky dialog choice
To achieve a 100% success rate on dialog choices:


 * 1) Go into the dialog menu (you may already be there).
 * 2) Quicksave.
 * 3) Identify the direction/button of the dialog choice you want to use ("Up arrow","X Button",etc.).
 * 4) Quickload, and make sure to repeatedly press the aforementioned button while it is loading.
 * 5) You will have succeeded in convincing the NPC.

This is a useful way to bypass dialog choice minigame.

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:


 * 1) Going into V.A.T.S. and Highlighting the target or part you want to hit.
 * 2) Cancel out of V.A.T.S. and repeatedly press the fire button as you do so.
 * 3) Hold the V.A.T.S. button again to quickly slow down time again and select another target.
 * 4) Repeat.

This is applicable in long-range engagements, but practicality varies. In close quarters, is more consistent.

Physics engine glitches

 * Sometimes V.A.T.S. will end and seem like the target was missed, but then 2 seconds later the bullet hits. This was tested multiple times at point blank and ranged V.A.T.S. The target can be used as a meat shield while the bullet is "frozen"
 * On occasion, Dogmeat will sit as if in his doghouse and spin in place. While this is occurring, no movement commands work i.e. "Go" then point to a location, "Sit Doghouse", etc. Solution is to start traveling any direction so he runs in front to lead the way. It may reoccur if you then stop moving. Rebooting the PS4 from a full (non-sleep) power-down may solve this or it may go away on its own.
 * You can walk backwards up any wall in the game by dropping an item, crouching down, grabbing it without putting it in your inventory (hold X on PS4), standing up, and walking backwards towards a wall. Works best with flat walls and walls that don't have a lip at the top as you might end up falling once you reach the lip. Fall damage still applies while doing this. Use power armor.
 * with the 1.0 build, it is possible to fly by grabbing an item you are standing on. This may kill the player though.

Infinite XP
After reaching The Prydwen and completing the Fort Strong quest, speak to Proctor Teagan (Weapons Merchant) on the Prydwen. Ask him about extra work and he will give you a mission acquiring crops from the citizens of the Commonwealth. The first location will be a random settlement (Tenpines Bluff and Sommerville Place confirmed) and after completion will award around 100 caps and 125 XP (leveled, above level 50 rewards 390XP). Asking for extra work again will give you the exact same quest as before, convincing the same settlement to contribute crops. Repeat for unlimited XP and Caps.

After reaching the Brotherhood of Steel's Prydwen, you can go up to Proctor Quinlan and ask to do a scribe escort. After he gives you the quest, you can head out to the flight deck (Where you can see an area near a couple of barrels) and you can kill the scribe in secrecy. Once this is done you can return back to him, saying the scribe died, and it will award you with XP and caps still.

Alternatively, instead of sniping the scribe from the flight deck, you can choose to fast travel down to the airport, sprint to him, and speak with him as to get him to follow you. In this manner, you can "beam him up" back to the Prydwen by once again fast traveling back to it. Now, take the scribe to an area where you can execute him in hidden (best done by going into the Quarters at the end of the hall, just behind you when you enter the main hall.) Executing the scribe in person will net you 3-5 stimpacks and a holding of fusion cells, usually 16. Make sure you're not seen and kill the scribe quickly (easily done by temporarily setting the game at very easy and stealth killing him.) You can then turn right around and speak with Proctor Quinlan just down the hall. Rinse and repeat for a healthy supply of stimpacks and fusion cells to go with your exp and caps.

You will receive the same amount of caps and XP whether you complete the mission as normal or simply kill the scribe.

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. (It can by quicksaving and reloading in between each try)
 * One location with such a safe is Cambridge Polymer Labs near a desk in the upper floor of the lab.
 * Another location is in the Security office to the left of the main entrance in the Super-Duper Mart in Lexington. NOTE: at level 7, it is only an advanced lock (please confirm)

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.

Earn more caps and exp
While talking to someone about a task, when comes the option to ask for more caps, Quicksave while you're still in the dialog, then you select the "More caps" option. Don't worry if you failed, cause you only have to reload from the Quicksave and try the option again. Reload the Quicksave till you succeed. You can freely do the same if other options for "more caps" appear.

Note
It works better on PC where you can quickly press F5 to Quicksave and F9 to load the last save when the latest is the Quicksave.

Effect exploits
Bleeding effects stack and do not extend. Meaning high ROF bleed weapons do increased damage.

Non-player character-specific exploits

 * Dogmeat is able to fetch a variety of items:
 * The Cryolator which normally requires Master lock picking
 * Can be used to duplicate items:
 * 1. Drop item
 * 2. Command Dogmeat
 * 3. Have "Dogmeat pick up xxx" (Best if he's a distance from the item)
 * 4. While he's moving towards item, adjust position so reticule changes for you to "Pick up xxxx"
 * 5. When he approaches, Dogmeat will stop and dip his head to pick up item. JUST as he starts dipping his head, pick up the item.  You'll hear the "picked up" sound and Dogment will appear to have nothing in his mouth.  He'll come to you and drop the duped item.
 * This works with bullets or any stacked item. After Dogmeat drops the duplicated item, one bullet/one item from the stack, drop the rest of your duplicated item inside your inventory on to the ground. Quick save then manually quit to the main menu reload the quick save and voila you now have two copies of the stacked item.
 * NOTE: For PC players, it only works on low FPS count (24-30 FPS is ideal for this)
 * As for magazines, will work with You're SPECIAL! only, allowing the character to max out his/her stats. After picking up a duplicated item, drop all issues and upon picking them up, you'll get the Choose Stat window.
 * Also works well for duplicating vendor shipment papers for materials such as Adhesive or Aluminum
 * Armor however is near impossible to duplicate this way because he simply grabs near the beginning of his animation giving you little chance to grab it before he does


 * It is possible to have 3 companions by meeting X6 88 to hunt the rogue then simply not going to the targets location he will follow you as a 3rd companion anywhere you go however he will fight with BoS and other various allies, Travis the radio dj can become a permanent follower the same way giving you 3 companions to change their gear drop weapons or armor and have them walk over it they will pick it up rarely.


 * Reseting the Approval Cooldown (Crafting a Mod for Codsworth / Preston or picking a lock for Piper) can be reset by reloading.


 * All companions (except Dogmeat ) are able to pick up an infinite amount of items even when their carrying capacity is maxed out. You simply drop the item you want them to carry and then command your companion to pick the item up. They will pick the item up and put it in their inventory regardless of the weight they are already carrying.
 * This does not let the companion carry more items through "Trade".
 * Some Companions will refuse to pick up items that are marked as stolen so they must be added through "Trade" or carried yourself.

Companion Character and settler clothing Glitch/Exploit
Companions and settlers can be reduced to wearing only underwear. This doesn't work on Dogmeat or Danse Trade with a companion/settler Give them a Dress (fancy,red it doesn't matter) and then press Y to have them equip it. Their previous clothing now is listed in their inventory, take it. Now give them chest armour and press Y to equip, they remove the dress, take it. then unequip and take the armour and they have nothing.

Also works with full body suits eg:radiation suits. Equip a full body suit then equip a hat then unequip that hat.

Gameplay exploits
Sentry Tower - An exploit used in order to keep a 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 intentionally detonating/ tripping them then if you reload the traps will be pre-tripped/detonated (bottle caps from bottle cap mines are not there)

In Saugus Ironworks, mini-boss 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, then when you reload from that save, all the baddies will remain friendly until you fire at them. This affords you the opportunity to lay numerous mines at all of the enemies feet, which do 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.

Patched Exploits
The infinite caps exploit has been patched as of 12/9/15, with Patch 1.2.37.0.0 (confirmed.) (Glitching ammo from vendors for infinite selling caps.)
