I summon and bind the power of Wikipedia!
What’s a role-playing game?
Wikipedia, speak again! (Note: Delta Green is usually played as a tabletop RPG.)
The original sourcebook, Delta Green, remains the most essential resource for running a Delta Green game. Delta Green: Countdown, Delta Green: Eyes Only, and Delta Green: Targets of Opportunity widely expand and enhance the setting. Those Delta Green products were written for Chaosium’s Call of Cthulhu role-playing game, so understanding that game’s rules and settings will enhance your use and understanding of Delta Green.
In Delta Green, nothing is canon. Consider the novels, short stories, and online articles the way you would consider logs or journals of other players’ games, as examples of stories or games which other players have experienced. All players are encouraged to use what materials are appropriate and most effective for their games, whatever the source. Use what works; do what you will with the rest.
Different writers have different styles, attitudes, and ways of presenting Lovecraftian horror. In addition to Lovecraft himself, Delta Green tends to associate itself most closely with Ramsey Campbell and Robert Chambers, and least closely, in many ways, with August Derleth and Brian Lumley.
