Millions of fans worldwide have undoubtedly been playing Call of Duty: Black Ops 3 as much as humanly possible since its release last Friday. With such round-the-clock gaming going on, there’s a good chance that the majority of the title’s players have completed Call of Duty: Black Ops 3‘s normal campaign mode, which unlocks the first-person shooter’s “Nightmares” mode.

Instead of simply increasing the difficulty of Black Ops 3‘s campaign mode, “Nightmares” lets players run through the solo story mode once more, adding new narrative pieces, as well as zombies galore. As seen in the trailer for “Nightmares” below, the walking dead have ultimately overtaken the globe with a population of 7 billion to humanity’s remaining hundreds of millions, putting players in a fight for mankind’s survival.

“Nightmares” is Black Ops 3‘s fourth main mode, folliwing the initial story campaign, multiplayer, and the popular standalone Zombies. Not to mention, the game features tons of Easter eggs to discover throughout playthroughs, including a pretty expansive top-down twin-stick shooter mini-game called Dead Ops 2 Arcade: Cyber’s Revengening.

As it happens, Treyarch went on to assert that varying the story mode’s style with “Nightmares” was apart of its strategy all along, saying, “It’s part of our studio’s DNA to launch a game with a few surprises.”

If anything, “Nightmares” ought to make for a richer experience, and please Black Ops 3 fans with new surprises by way of added plot, gameplay, and cinematics. However, last-gen gamers are almost certainly missing out on the fun, as there is no campaign mode on Xbox 360 and PS3.

With so much first-person shooter action to delve into, fans of the game should definitely remain busy for quite some time. Plus, in the coming days, weeks, and months, players will become more acclimated to the title, making it the accepted hub for all things Call of Duty. In the end, fans’ gravitation toward the newest installment should slowly siphon off the 12 million active players still getting their FPS fix in Activision’s and Treyarch’s prior installment, Black Ops 2.
