Euclid's C-Finder

Euclid's C-Finder is a weapon in Fallout: New Vegas.

Characteristics
The raw power of the sun, contained in an easy-to-carry package! Just point this weapon at the bad guys, and push the button. The Archimedes II orbital laser will strike down at the speed of light and reduce your foes to bones, beaks, and toenails. Once you use it, you will have to wait 24 hours for the laser to recharge. Many locals appear to flee from the Tracking laser. You must choose to route power to the Archimedes II ONLY during the quest That Lucky Old Sun. This item has a weight of 15 and a value of only 1 making it only worth finding if you route power to the Archimedes II. If you have Veronica Santangelo as your companion it starts the I Could Make You Care quest.

Locations
Found at the Freeside's east gate. A boy named Max carries it. He is chasing a girl named Stacey. You may either buy it for 1000 caps, or it can be pick pocketed from Max while he is sleeping, you may also do a barter check(50) and buy it for 25 caps. Max sleeps on the second floor of the building on the right if you enter Freeside from the East Gate. You can also barter Max (barter 45 required) to sell it to you for 20 caps. However, the gun will not work unless you choose to route power to Archimedes II during the quest That Lucky Old Sun. The gun might also be found sold at the junkyard north of Helios, though it only seems to appear occasionally after enabling Archimedes II.

The Euclid's C-Finder appears only in Fallout: New Vegas.

Enable Cheat
If you don't mind console cheating, you can manually enable the c-finder no matter what option you chose at the end of the That Lucky Old Sun quest: Enables the satellite, and will give you the normal behavior, e.g. one shot per day. If you want to use it more often, the ammo code is m so   will give you ammunition for 100 shots.

Note: The C-Finder seems rather buggy (well, buggier than the rest of the game, anyways), so save before using it.

Trivia

 * Euclid was a famous Greek mathematician. Among other things, he invented geometry.
 * The name of the C-Finder, and the graphics it shows the player while it is operating, are a reference to the Pythagorean Theorem.

Bugs

 * It is possible to obtain multiple copies of the weapon. If you buy the weapon for 1000 caps from Max in Freeside, then wait a bit, he will have another one for you to buy later on. Having multiple copies of the weapon gives you multiple charges, although you will only have one charge at one time, as this is replenished once the charge is used.


 * It is possible to obtain infinite ammo for this weapon. Normally you can only get 1 charge at a time but it is possible to stock up an endless supply of ammo by using the storage glitch. See - http://www.youtube.com/watch?v=ulJOlXqumE


 * Sometimes the Euclid's C-Finder will not fire after targeting an area leading to the tracking beam following your movements constantly. A possible fix for this is to save and reload your game: watch out because this may cause the laser to fire on where you are standing within a few seconds of the reload. Another way to fix this is to wait the tracking beams out. Again be careful: if you enter within a certain range of the beam and stand there, the beam of energy will come down and destroy you. To avoid this, aim your current weapon at a more distant target. This should cause the beam to discharge away from you. Sometimes fast-travelling somewhere will fix it. WARNING the weapon may remain in this state indefinitely making it a waste of space and money, given that you won't be able to fire it again. Potential Fix Found: Open the console and type player.additem e07d1 1 to manually add the Archimedes II laser itself to your inventory, then equip and fire it once. This fixed Euclid's C-Finder for me.


 * When the tracking lasers appear but it does not fire, restarting the game might help, it did for me anyways. (conformation?)


 * It is possible to make Max become aggressive to you if your pickpocket attempt fails. He will constantly run away from you and due to your character being unable to kill children he will stop you from being able to wait in or fast travel from his current vicinity in Freeside.


 * When set to hot key, shows the symbol for Guns based weapons, rather than Energy Weapons.


 * Firing while under the influence of turbo causes the game to crash. (Only tested on PC)


 * When attempting to fire at any location, the game will freeze. (After activating Archimedes-II at Helios One)(Usually related to having the perk 'Heave Ho!')


 * Max will somehow end up beyond the edge of the playable area on the extreme Northern part of the map.


 * It is possible getting 3 of these if you pickpocket Max, come back later and by it off of him, then come back later with the I Could Make You Care quest and buy it or pickpocket him again.


 * It has always taken 48 hours to receive a charge for me (PC). Not sure if this is intended or not, maybe its 24 hours in hardcore and 48 in regular I haven't tried hardcore. I need confirmation.
