The Big Zombie Easter Egg In Black Ops III Is Insane

This is one seriously tough Easter egg.

Treyarch, the creators of Call of Duty: Black Ops III, have put a secret mode in the latest first-person shooter game. Treyarch has been putting the zombie co-op play mode in its Call of Duty games for a while.

Zombies even makes an appearance in the single-player campaign of Black Ops III. But if you play through the entire campaign mode, you get a special Easter egg, or concealed inside joke, as a gift from the developers at Treyarch. It comes after the credits end. If you wait long enough, you’ll see that in the main menu, you can unlock something called the 'Nightmares mode'.

You can skip the credits by moving the analog stick. In the new Nightmares mode, you can play the entire single-player campaign over again, but this time with different characters and a different narrative. The characters are zombies, and it’s taking place in the zombie apocalypse universe. If you really like single player campaigns, this is a pretty huge gift, and it is separate from the zombies mode.
