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 benefit.

Quest-related

 * 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.


 * Once in New Vegas, go to the Atomic Wrangler and pick up the quest "Wang Dang Atomic Tango". Find and recruit "Old Ben". Go back to the Wrangler and talk with him again. As long as you have 50 points in Speech you can cycle through the hire dialog and get 50 Exp per cycle.


 * 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 guy 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.

Barter- and repair-related

 * The Infinite Money Glitch is back, 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, rinse, repeat.

Infinite Caps, NCR, and Legion Money(360?)

 * After the Casino opens in Primm, it is possible to repeatedly turn in chips for either caps, NCR notes, or Legion Coins. Just simply keep selecting the exchange chips for money option, then select which ever currency you want. This still works even after you have been banned for winning too much.
