Okay I'm my story is gonna be a little confusing without some context so here are some things to keep in mind.
*There will in dialogue sometimes skill checks, S.P.E.C.I.A.L checks, perk checks, basically anything in the game in dialogue even new perks
*The story will have PRACTICAL weaponry because I have problems seeing the survivalist rifle in some fanfictions which is an extremely broken down and worn rifle with a limited capacity and just shoots so you will see some unusual choices here
* There would be some wild wasteland except with modern-time references or whatnot
*And some chapters would have flashbacks or called memories where we go to the journey of the Courier before the plot of the story.
*This would take place from a 3rd person perspective
*At some chapters or memories at the end there would be stats, weapons, and all that stuff so keep that in mind
*And finally the Courier's stats will be as realistic as possible considering the DLCs, his feats in the game,etc
*Ammunition is to be ignored
and that's all enjoy
