Fallout: New Vegas

You can locate the field "gun" for the ARCHIMEDES weapon by entering the Freeside's East Gate and locating the two children chasing each other (not chasing the mutated rat) during daylight. Talk to the one possessing what appears to be a toy gun. You can purchase the gun for 1,000 caps or 20 caps with Barter at level 45 or greater. To use the weapon you must supply the power to ARCHIMEDES II during the "That Lucky Old Sun" mission.

By using this method, it is possible to repair any and all items to the player's current repair level without using any of you caps. To do this you, need the Confirmed Bachelor perk and enough caps to cover the repair cost of the item. When you arrive at the Mohave Outpost to get the pardon for the new sheriff of Primm, during the conversation with Major Knight a Confirmed Bachelor speech option is available. Select it, and whenever you do repairs through him, the item gets repaired to your repair level but the caps do not get deducted from your stockpile. This can be very useful when combined with any unlimited caps trick, and results in your player having all items at 100% condition (even things like the Fat Man, where replacement parts are difficult to find).

Go south on the road out of Goodsprings. After about 100 yards you will find a refrigerator at the base of a hill. There is a skeleton wearing a fedora inside.

If your speech skill at 50 or higher, you can persuade Old Ben to offer his escort services to the local bar, if you succeed in the Speech Challenge, you'll gain 61 XP. If you follow him back to the bar afterwards and wait until he sits down, you can speak to him again and redo the same Speech Challenge over and over again for infinite XP! You can find Old Ben sitting by a fire close to The King's headquarters in Freeside.

Go to Old Mormon Fort in Freeside. Find Julie Farkes inside the Fort. Choose the dialogue option to help them get medical supplies. Go through the dialogue options to hear one that tells you that she just got a shipment of magazines. Then, choose the "I have some medical supplies to drop off" option. There will then be three options; choose the "Rad-Away" option, as it is the easiest one of the three to find. You only need to leave one thing if you do not care about fame. Every time you give them something, you will gain more fame. After you give them the supplies, choose the "I'd like to buy medical supplies" option. There are a few aid supplies there that you can get if desired, but they will not regenerate. In the supply list, you can find the magazines. Buy any desired magazines, and then exit. You can then choose the option to give med supplies again. This time you do not need to give them anything; simply choose the "Never mind" option. Go back to "Buy medical supplies", and you can repeat the process for more magazines. You repeat this as many times as desired as long as you choose to drop off supplies first. You can even come back to do it again at a later time. You can get the following magazines: Fix-in' Things (Repair +10), Lad's Life (Survival +10), Meeting People (Speech +10), Programmer's Digest (Science +10), Salesman Weekly (Barter +10), and Today's Physician (Medical -10).

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 exploit again.

Get a large object that you can push or pick up. Drop it next to a standing NPC that is not leaning against a wall, doing push-ups, or sitting. Run against the object and it will damage the NPC without becoming them becoming hostile or you losing reputation. Repeat this until the target is dead. Note: You may take some damage, and the object may fly away.

Every Skill has a designated skill book. One seems to be missing. There seems to be only three explosive skill books where there are supposed to be four. This last skill book can be found on the desk in the office of the "Ranger Station Foxtrot". The other three can be found in "Nellis Air Force Base", "Sloan", and "Mojave Outpost".

In Camp McCarran where the monorail directly to the strip is located, you can gain entry to the monorail. Take the long way around and stay as close to the vending machines as possible. Follow the wall around the back way. Make sure the other soldier has his back to you. Crouch and sneak up to this soldier. You may hear the phrase indicating that if you get any closer they will have to shoot you. However, as long as you remain hidden, it may flash "Detected" briefly for a few times. As soon as you are close enough to the door, you can go through it and take a monorail directly to the strip. This may require a few attempts. Be careful when returning to the monorail from the strip. You will probably be shot. However as soon as you enter the monorail it resets, and you can again ride it back to the strip. By using this trick you can bypass many annoyances and quests, and can skip directly to meeting Mr. House and finding the person who shot you.
