Five Nights at Freddy's Books and Games in Chronological Order

The games hide their timeline in clues, so this follows the most common reading of them: Secret of the Mimic in 1979, then the 1980s of the fourth and second games, the first game, and on to the Mega Pizzaplex. Each book series sits where its framing story happens, and the novel trilogy, its own continuity, is placed next to the first game it reimagines. It's a good way to see the whole story laid out once you've played everything. On a first run it spoils far too much, starting with the very first entry.
