Game developers Activision and Treyarch have released this week the new "Call of Duty: Black Ops III" gameplay trailer featuring a new campaign and the fan-favorite "Zombies" mode. It was said that the new gameplay focuses on "The Giant," which is a pre-order bonus map. Both the new campaign and multiplayer mode have surfaced online ahead of the game's official release date on Nov. 6, a report from iDigital Times said.

According to the report, the gameplay footage was first spotted at the YouTube channel BANG. The video shows a 30-minute gameplay of the game's new "Zombies" mode. Shown in the video is "The Shadows of Evil," which is part of the upcoming multiplayer mode.

"The 1st plot you'll follow in Zombies Mode has been dubbed 'Shadows of Evil.' Players will take control of four troubled individuals - Nero (Jeff Goldblum), Jessica (Heather Graham), Jack Vincent (Neal McDonough) and Floyd Campbell (Ron Perlman). They're all transported from Morg City to sinister version of their home that's filled with the undead. All the while, the Shadow Man (Robert Picardo) hangs in the background and aids the group of four," Heavy said.

In "The Giant," the second bit of Zombies mode, players can assume the role of four characters from "Black Ops 2" map "Origins." They are Tank Dempsey (Steven Blum), Nikolai Belinski (Fred Tatasciore), Takeo Masaki (Tom Kane) and Edward Richtofen (Nolan North). The mission is "to down zombies and alter the timeline of their original conflict. This Zombie Mode campaign starts shortly after the events of 'Origins,'" the report said.

In addition, players can buy the game's "Juggernog Edition" and collect several expensive items presented below, as reported by Heavy.
