Appendix N File is our curated vault of espionage and action-thriller inspiration for tabletop roleplaying games. Just as Gary Gygax’s famous Appendix N in the Dungeon Masters Guide fueled the imagination behind Dungeons & Dragons, this modern reimagining pulls from the best in spy fiction, covert ops, and cinematic thrillers.
Inside you’ll find essential novels, classic films, and standout TV series that capture the mood of secret agents, tradecraft, and high-stakes action. Whether you’re running a campaign of espionage RPGs like Night’s Black Agents, Delta Green, or your own homebrew spy thriller, the Appendix N File gives you a ready reference of stories to mine for characters, plots, and atmosphere.
From Le Carré to Ludlum, from The Bourne Identity to Mission: Impossible, this list is designed to give game masters and players alike a toolkit of genre-defining works. Use it to build tension, twist conspiracies, or simply immerse your table in the pulse-pounding world of modern spycraft and action adventure.
