~ is the key to open the Console in the PC versions of Bethesda's games (USA Keyboard layout). You can easily be a god if you know the different commands xD
resurrect is the command that will be used to revive the nuked NPC.
If you don't want to use the console, then you have to reload a save pre-nuke. --- Too bad we can't see the Wright side of life, EA is blocking the view. Welcome to the realm of the Electronic Assassins. TGIF: Thank Gawd I'm Female
Would using a console command to resurrect an NPC have any problems down the line?
For ex; the other NPC's think someone died, even though hes standing next to you? --- 85 Healadin - ScrubBusters - EU-The Maelstrom http://eu.battle.net/wow/en/character/the-maelstrom/Nekovivie/advanced
While I did bring up the console I really reccomend that you don't use it and just deal with the consequence if you can't reload an older save.
It's something that'll haunt you if you use it to do anything but fix* glitches/getting stuck/field of view. Trust me, people have ruined Bethesda games for themselves by having knowledge about the console.
