Plot

Single-player campaign

Call of Duty: Black Ops III takes place in a dystopian future set in 2065, 40 years after the events of Black Ops II. Air defense systems have advanced to a point where they cancel each other out. As such, most of the warfare between countries is done by covert operatives fighting behind enemy lines. Science and technology have radically changed both the landscape as well as the future of the human race, with society violently protesting and attempting to halt further advancements touted by scientists as "progress".Military technology has progressed to the point where robotics play a main role in combat, and supersoldiers have been developed to fight in the battlefield. Humans have reached the point where they are considered to be more machine than flesh and blood. As a result, there is speculation and fear about an eventual robotic takeover. The game will follow a team of black ops soldiers, like previous installments in the Black Ops series, with supersoldier capabilities.

Zombies

There are two confirmed Zombies storylines in Call of Duty: Black Ops III at the time of its reveal. One story focuses on a new group of characters: Nero (Jeff Goldblum), Jessica (Heather Graham), Jack Vincent (Neal McDonough) and Floyd Campbell (Ron Perlman), who reside in the fictional Morg City. Treyarch describes the new characters as "troubled individuals" with "a long and sordid history of past misdeeds". The four characters are thrown into a twisted version of the city, overrun by zombies, and are guided by a mysterious, unreliable figure called the Shadow Man (Robert Picardo).[5] Treyarch says that their story will tie into the main Zombies storyline in the past games, particularly "Mob of the Dead" from Call of Duty: Black Ops II.

The second story focuses on the alternate versions of the original characters: Tank Dempsey (Steven Blum), Nikolai Belinski (Fred Tatasciore), Takeo Masaki (Tom Kane) and Edward Richtofen (Nolan North), which were introduced in the Black Ops II map "Origins". Their story continues from where "Origins" left off, as they attempt to rewrite the original timeline's history.
