On the map, there is a latitude and longitude, and for each location, there is a specific zone number that goes along with the location’s name, EG: Vault 106 is located in zone 5, section 12, so it is designated as 5.12. To get the lat/long, think of laying out an imaginary X-Y axis on the map.
This is a list of all 23 schematics to create the seven custom weapons. Basically, the more components you have when making a weapon, the stronger they’ll become.

Does any one know of any places where i can’t parts for the railway rifle? I can not find a steamgauge assembly anywhere.
In the robco factory there is 2 mark 4(i think) turrets at either side of the stair leading to the second floor. There is also 2 protection droids and a Mister Gutsy. Dell with mister gutsy last and find a good piece of cover his plasma gun is deadly. pop in and out of cover and shoot him when he is not firing or he will kill you in less than ten seconds.
okay. look. clear and concise answers should almost be mandatory for a post. that being said, can someone help with the locations of the railway rifle. and i agree, if you can’t find any misc. piece of anything you don’t play the game enough. schematics are different though. thanks to those who help.
where can i get a dog
FUCK YOU ALL TELL US HOW TO FIND THE LAT/LONG
go to the super-duper mart and in the pharmacy there is a bunch of stuff that can help you with schmatics
misc. items are everywhere, literally raid everything, that what i do. and if you get multiple schematics for the same weapong it will increase its effectiveness. there are 3 schematics for all of the”build you own” weapons
I got lucky and found the firelance on a raider i killed near evergreen mills.
where the hell is the upgraded version of the fatman please help
TO PIEBOB
TAKE THE TENPENNY TOWER QUEST WHERE YOU EITHER KILL OR HELP THE GHOUL. GO TO HIS LOCATION AND THERES ABOUT 5 ON HIS SHELF. MUST STEAL SO KEEP HIDDEN
Remember that Jesus loves you
where are the alien crash sites
Are these all of the schematics? I was running around in the game looking for others! lol
there is only one dog in the game his name is dogmeat, no really, you can find him in scrapyard.
