Fallout: New Vegas exploits

Exploits are "holes" in the game programming which allow a player to do something which the developers did not intend and alter the play balance in a way which cannot be rectified.

=General considerations=
 * Exploits are repeatable consistently.
 * Exploits are attainable with an unaltered game on an unaltered system. Third-party mods must not be present.
 * Exploits give the player some unintended benefit.

Experience

 * In the quest Three-Card Bounty after killing the fiends you can talk to Major Dhatri About Ten of spades and Betty if the player has a speech skill of 35 and 46, respectively, you can keep getting 20 XP from the speech check.


 * In Vault 11, inside the sacrificial chamber, you can access the mainframe in the room to the left after sitting through a presentation by Vault-Tec. Once you access the mainframe, you can repeatedly earn 550xp every time you select the third option and you do not exit the mainframe. Confirmed on Xbox 360 (still works, Oct 30 2010), Confirmed on PS3


 * During That Lucky Old Sun, if the Courier chooses Full Region (Emergency output level), the dialogue option with Ignacio Rivas to turn in the quest is not removed upon completion. This allows you to obtain 350 XP, 3 Stimpaks, and 2 Doctor's Bags as many times as you like. After the words "Level Up" appear for the first time the experience will cease to show but it will still make the sound as though you were getting experience. Once you exited out you will not hear the sound or see the experience show up, but you are gaining it all the same. Both statements also apply to the items.(verified on X360 and PS3)


 * At Aerotech Office Park talk to Captain Parker about Keith. Find Keith in Aerotech Suite 200. With a Barter skill of 45 you can repeat a Barter Check indefinitely for 50 experience each time.


 * In Freeside if you have a speech skill high enough to convince Old Ben to work for James Garret, but have already recruited Santiago you will find him Ben sitting at the bar and be unable to tell Garret that Ben is willing to join, but are able to talk to Ben again and repeatedly turn in the speech challenge quest for 50xp. (confirmed on ps3)


 * In Goodsprings during quest: Run Goodsprings Run: Reward: Inifinite XP, speech check & loot
 * Agree to kill Ringo for the Run Goodsprings Run quest, kill him, return to Joe Cobb, agree to shake down store owners for supplies. Kill all the gang members, including Joe Cobb for good karma (and thus failing the quest).
 * Go to Chet in the generals store and ask him to donate some supplies to the Powder Gangers. Select the first option (barter 25), then the second option (speech 25), afterwards the dialog doesnt disappear, and you can keep shaking him down indefinitely.
 * Loot from Chet: 25xp, a completed speech check, some Powder Gangers Fame (which you really need, since you just killed a whole bunch of them), 1 leather armor & 30 9mm rounds, which can be sold back to Chet, unlike what ever you steal from him.
 * You can do the same thing with Doc Mitchel (need medicine 25), the town's doctor. Rewards is 25xp, a completed speech check, spare medical supplies (worth 100caps, and weighs nothing).
 * (Tested on PC, ps3 confirmed)


 * In Camp Golf, accept the quest Flags of Our Foul-Ups from Sgt. McCredie, then go talk to O'Hanrahan and mention helping the squad, he'll ask you to talk to the misfits. Go find Razz, the man with the mohawk, and ask him about his squadmates, as long as you have 40 speech, you can repeat the dialog over and over again for 40xp each time. (confirmed on Xbox 360 and on pc)


 * In the Vegas Strip when you talk to Mr. House you can ask him as often as you want about the "You´re seem more like a computer than a man." Which requires 35 Medicine Skill and always gives you 35xp.

Money

 * After recruiting Fisto to work for the garrets as their 'sex bot'. Talk to him at the atomic wrangler, he will offer to provide services to you. Just exit the conversation and you will receive 10 caps. Repeat this as many times as you wish to build up vast sums of money however quite slowly.


 * In Primm, once you get the town a new sheriff, wait three game days outside of the town. Then, walk into the Vikki and Vance casino and deal with the drifters. Next, leave Primm again for 3 days and wait. Once you return, the Vikki and Vance casio should be up and running again. Go to lady behind the counter who sells chips. The exploit is that she will never take back your chips when you exchange them back for caps or any kind of currency. With this glitch, it is possible to reach +1,000,000 caps in less than five minutes. This glitch has been patched with the first update but you can just clear your cache, get your money, and then re-install the updates


 * Any trader who plays caravan can be exploited for caps. There seems to be a logic error that involves all the different types of currency, if you buy everything so that you have no caps you can still gamble with your NCR and Legion money, the game gives you back all the money in caps. If you continue to do this until the the Trader has 20 to 30k it never diminishes his/her total caps. You can keep feeding the Trader more caps by buying and selling stuff. WARNING: DO NOT make bets of over 49999 caps or the game will crash on payout. So once you get the trader up to around 180k caps you can just match bet and make more money then you can ever need.


 * Go to any Casino in New Vegas any get at least 200 chips from the person behind the counter and go to a slot machine. Save before you use it and bet max and it'll bet 200 chips. If you lose then load and try again. WARNING: DO NOT exit the slot machine before loading (the game somehow knows when you load and try again and marks it as cheating, so you cant use it for 1 minute). keep trying and every time you win exit and save again. Keep doing this for more chips. (Also works on blackjack and roulette). Keep in mind the casinos will ban you from gambling once you make a certain amount of money.(It has been fixed you still have to wait for the minute after loosinf and reloading)


 * At HELIOS One, if you chose not to reroute power to Archimedes II, Ignacio Rivas will give you 3 Stimpak's and 2 Doctor's Bags, if you continue to click on this option he will continue to give you these medical supplies allowing you to sell them and resupply your Stimpacks at anytime.


 * At every casino there is a certain amount of money that you can make before your banned from gambling there. However there is a way around this that will allow you to have infinate money. It has to do with the different currency's in the game. Here's how it works, go to any casino and gamble until you have a certain amount of money (you should probably look up the amount of money you can earn before getting banned an keep that in mind) then you can exchange your NCR and/or Legion money for chips. Then go to a Blackjack, Roulette, or Slots and LOSE all your chips. This causes your total earnings from that casino to decrease allowing you to then gamble some more and win more money without having to worry about getting banned from gambling.

Loot

 * When doing the first quest to help the town folk get rid of the gang in town, run to the mine and follow a mine worker to the gang's hideout. The mine worker will kill the gang, and you can loot the bodies. Now, complete the quest by going back to town and activate the final fight. You can loot the bodies a second time.


 * In any shop,enter with a bucket and place it in front of the desk that has items on,pick up the items on the desk(do not steal them)and put them into the bucket.Once done save,this makes it easier in case you spill the goods in side of the bucket.Move the bucket to a room which has a door this is best done while crouching,it decreases the chance of your bucket spilling.Once you have the bucket in the enclosed room steal all of the items,this does not effect your karma or your faction standings.

Artificial Intelligence Flaws

 * The artificial intelligence governing Deathclaws is unable to correctly determine when a player is within reach.
 * For example, in Quarry Junction, deathclaws do not attack players when they are mounted on the taller rocks or machinery, even when they are in reach. This flaw in the deathclaw AI can be exploited to safely kill the Alpha Male and deathclaw Matriarch even at lower levels. However, when deathclaws are actively pursuing the player onto rocks or machinery, they will recognize the player as within their reach, allowing them to attack.

Barter and Repair Exploitation

 * The infinite money glitch still works!(11/1/10) Go to a store that has two identical items with different values. Buy the cheapest, and you should be able to sell it back for more. Repeat. Note: if you have a heavily damaged item that usually costs a lot of caps ( I used a minigun worth 12 caps and sold it to the Gun Runners), sell it to any store that already has that item. Exit the sale screen and dialog, if it is still there you can buy it back. When you buy it back it is fully restored and you can sell it for max price (depending on your barter). Repeat until you clean them out. Note: this does not work when trading with the Brotherhood of Steel at the Hidden Valley Bunker. The merchant had well over 50,000 caps yet every time I sold the item back to the merchant the display said I should get 3007 caps but when I accepted the transaction I received no caps. This means that I bought the item for a small number of caps and sold it back for no caps making me lose money.


 * After the Casino opens in Primm, when you choose to cash your chips in, no chips are removed from your inventory even though you are given currency for the chips. The player can cash chips in indefinitely for an infinite amount of NCR currency, Legion currency, or caps. - Removed in the PC,PS3 and Xbox 360 Version after patching.


 * In any shop that displays their items out in the open you can pick up the item, take it to a back room, and shut the door. From there you can pocket the item without any people attacking you, go back through the door and sell it back to them. After a while they will display the item again so rinse and repeat. In the Silver Rush in Freeside there is no Karma loss.


 * Using a suppressed sniper rifle, kill ncr veteran Rangers, and take their armour, which can be worth up to 7500 caps. the spawn at camp Forlorn Hope. make sure you are hidden before you kill them and no karma or faction penalty will be incurred nor will the NCR attack you.  simply sell their armour, fully repaired for max profit, and everytime you fast travel to and from the merchants, the veterans will have respawned, if not go to camp delta.


 * After picking the lock at the gun runners gate once, they will all begin attacking you where you can kill them without karma loss. Each of them wears a combat armor worth around two thousand caps.  After a while you can go back, where two guards will be hostile to you. Kill them, loot armor, sell it.

Karma
Flame damage kills do not count against your karma.

Followers
(although sometimes it requires the command to be pressed rapidly 4 or 5 times). Works on all versions of the game.
 * In the middle of battle, talk to your follower. Select the 'Stay at a Distance/Stay Close' option twice. Then exit the companion wheel. When you exit your followers health should be fully restored.


 * Increased follower weight limit: Give any follower that is near their maximum weight limit a small portion of ammo. You can then give them another small portion of that same ammo, and they'll still be able to carry it even if they go over the weight limit. For example, ED-E is at 200/210 weight and you have 20 missiles (weight of 3). You can give ED-E 3 missiles, which puts him at 209, then give him more missiles in sets of 2 until you're out of missiles, putting him at 260, but it displays it as 210/210. You do not lose any items, but taking off weight will leave your companion at their max weight until their actual weight is below their max weight. Tested on PC, patch 1.01, mods are present, need someone else to confirm this; confirmed X360, whilst Boone was a follower his weight was at 249/250, after giving him microfusion cells one at a time he continued accepting them no matter what the quantity was

Weapons

 * Using VATS then simply leaving it when using an Anti-Materiel Rifle loaded with Inc rounds (haven't tested other guns) will cause your target to catch on fire and take damage without causing aggression from friendly NPCs including the one you caught on fire or those watching. Only tested on the PS3 which has currently not seen any patches at the time of this exploit. Confirmed on the 360. - Patched


 * If you have done enough of the BoS steel questline that you are told you can have some of their recharged energy cells / mf cells, you can leave the bunker and re-enter it and the box will always be filled. You can do this as many times as you want and accumulate an outrageous amount of energy weapon ammo.

Freeside energetic
Using some doors in Freeside, such as the East Gate or shops, will count as an Energy Weapon kill upon loading of the entered area; a message will appear counting the killing of an enemy using an Energy Weapon, allowing for easy completiong of Energy Weapons-related challenges, and so achieving the XP you would normally earn upon completion of the challenge. Tested on Xbox 360.

Perks
If a perk has a required skill level(eg.Animal friend has a survival requirement of 45), allocate your skill points to the number required, select the desired perk and return to the point allocation screen. You can now reset your points and put them to whatever you want but the perk is still selected even though you no longer meet the requirement.

No falling damage
If one were to jump from an extreme height and save a bit before touching the ground, when they die and their save reloads, they will not take any falling damage depending on where they were relative to the ground when the save was created. Must be a hard-save, not a quicksave.

barrel exploit
The player can use barrels to kill people. Simply find a empty barrel and push it against a NPC. The NPC will lose some health and the barrel will be sent flying. This can be repeated multiple times to kill someone. The person or others will not be agressive when hit or killed. This allows lower level players to get armor and weaponry without karma or hostility. Note that you will also take some damage, but very little.

Armor Hopping
If you press grab just a few milliseconds after jump standing on a piece of armor you can jump on it repeatably to get high of the ground. This can be used to get to out of bounds, or places you are not supposed to be able to, like Legate's Camp.

Infinite Legion Loot / 12.7 Ammo
If you decide to massacre Caesar's Legion at The Fort, you have a chance to gain an unlimited supply of Legion money, armor, and weapons, as well as a possible source of infinite 12.7 ammo and 12.7 SMGs. After clearing out the main area of The Fort and searching the bodies, find the corpse of the Legion Decanus and carry it to the drawbridge where you entered the area from. Drop the body and activate the drawbridge, which takes you to the outer area of The Fort. Immediately turn around and go through the drawbridge again. Check the body of the Decanus and he should have his weapon, ammo, armor, and the spent shell casings he was carrying even if you had already cleared off his body. Repeat as many times as desired. Also works with all other human NPCs in the area with the exception of the Praetorian Guard.
