Infinite Caps
Once Primm has a new sheriff, The Vikki and Vance Casino will become open. If you save before every hand in blackjack, you can just load the game if you lose. If you go to the cash register, you can trade in your chips for caps. The NPC will give you the equivalent in caps, but will not take away your chips. You can do this infinitely.

Infinite XP
You need Speech of 30 or the perk Confirmed Bachelor. You must also be on the good side of NCR. Go to HELIOS One and the lady should automatically talk to you. Once she allows you access HELIOS One, you should be able to start the mission "That Lucky Old Sun". Follow the mission and talk to Fantastic and Ignacio Rivas. While talking to Rivas make sure you get him to reveal that he's a Follower of the Apocalypse by using Speech or Confirmed Bachelor and agree with his ideals about peace or just say you're neutral. Do the mission regularly until you get to the point where you activate the Mainframe Terminal. Configure the Power Grid to "5) Full Region (Emergency Output Level). Finish the mission by hitting the Reflector Control Panel outside on top of the tower. Go back to Ignacio Rivas and choose the option "I overloaded the plant. No one.....". The glitch is that the option never disappears, so you can choose to keep pressing it. You get 350XP, 3 Stimpacks, and 2 Doctor's Bag

Infinite Speech Check Loop
This requires a speech skill of 20. Talk to 10 of Spades in Camp McCarren. You may need to find out about Corporal Betsy's trauma beforehand. Anyway, open a dialogue with him and select "I heard about what happened to Corporal Betsy" then "Tell me what happened." Your next options will be the speech check or "If you were unconscious, how could you have done anything?" Do the speech check, then the other option is the only one available except "Never mind." After you select the unconscious option, the speech check will be available again, but grayed. Regardless, keep pressing A and they'll alternate. Even though the check is gray, it still counts as a pass. NOTE: This does not glitch XP as well.

Set fire to/kill enemies without using ammo!
Equip the Anti Materiel Rifle and load it with Incendiary rounds. Enter vats on any target, then exit vats without shooting them. Whatever you aimed at will now be on fire, with no ammo used.

Easy Kill
If you purchase or find the Anti-Material Rifle and then equip .50MG, Incendiary rounds. Equip both rifle and ammo and just target some one in VATS and then close VATS. They should catch on fire and lose some health. You can also select more then one person in VATS before closing it to burn more people using the right joystick. You will not aggro enemies or friendlies. Also you will not lose karma or Reputation twith each kill. Very useful if you need to kill a NCR/Legion with something you need on them.

Infinite xp in Vault 11
Aftr reaching the sacrificial chamber and dispatching the robots go to the computer terminal through the previousley closed wall and enter it. The bottom option can be pressed over and over again to gain 500 xp each time. If any of the other options are chosen or the terminal is exited you cannot use the eploit again.
