New Game Mode Available- NIGHTMARES

Logged on to finish up my videos today and noticed under multiplayer and zombies there was a mode called Nightmares.

I played for a couple hours. It seems like a Story Mode for Zombies. Pretty neat.
I'm not sure what the reward is for playing (calling cards, etc.) Zombies are super easy to kill in this mode. The box doesn't cost money so you can pick whatever weapon whenever you want. If you die, you just respawn at you last checkpoint. Has a nifty story to it, but honestly i'd say if you want to kill zombies go for regular zombies lol

Wasn't that already there?
I'm not into zombies so I could be completely mistaken.

To play the Call of Duty: Black Ops 3 Nightmares mode on Xbox One, PS4 or PC you needed to beat the campaign. After the new update arrived in December the Nightmares mode is now available for all users to play without completing any other part of the game.
