Wolfenstein: The New Order -- You Are Sleeping With The Serial Killer The Whole Time
The most recent Wolfenstein games take place in a alternate post-WWII universe wherein the Nazis have taken control (that's right, an alternate universe). Throughout the game, whenever you're not hanging out with Jimi Hendrix, you can find various newspapers clippings that teach you about the state of the world under these Nazis, with one of the tidbits being that there was a serial killer on the loose in Poland. Unfortunately, all the Nazis are a bit too busy to solve this cold case, since they're being brutally slaughtered by you.

If only those kraut detectives had access to the personal diaries of the Malowies Killer -- like you do. Throughout the game, your lover and kickass Nazi killer Anya will read to you from her dead cousin Ramona's diary. In the last chapters, it's revealed that Ramona was the one who strangled, sabotaged, and poisoned her way through Poland. Case solved, right? Except there's a twist: Ramona doesn't exist. The Malowies Killer is still alive, and she's calling from inside the hidden resistance bunker!
That's right, the serial killer was sweet and nurturing Anya all along. But you don't have to wait to the end of the game to find this out. You could just check the collectibles screen -- oh, and speak Polish. In the tab that collects all of the diary entries, there's a generic-looking photo of Anya narrating the pameitnik (Polish for "diary") like she's working on a new season of Serial ...

But if you squint hard enough, you can make out three words on the back of the book: "Nazely Do Anya"
BethesdaPamietnik? That's right, Anya is writing The Notebook.
