About This File
I hid all of my mods from Nexus in July 2021 to protest the removal of mod deletion. People still ask me for them on occasion, so I'm reuploading them to various alternative sites. I have no idea if this still works, as I haven't done modding for Bethesda games in years, so use at your own risk.
Original description from Nexus:
Warning: I am not responsible if you break your save by killing a quest-critical NPC.
Do you want to kill all the NPC's in Fallout 4? Do you agree not to file a bug report when you irreparably break your game? Then have I got the mod for you!
Does exactly what you think it does; allows you to kill any NPC, including essential ones [with the exception of children and NPCs you can't actually access.]
