Origins

"Every story has a beginning...and an end."

- "Origins" trailer

"Unleashed after the Germans unearthed the mysterious Element 115, this next chapter in the Zombies legacy will explore the saga’s origins as players reunite with an unlikely band of soldiers that come together to defeat the greatest evil the world has ever seen, using a period-specific arsenal that includes Wonder Weapons that harness supernatural powers, a diesel-drone and Mark IV tank, as well a new perk machine and power-ups – and that’s just the start. Players will need all the help they can get to succeed in defeating the undead, as well as evading an unprecedented 1,000-foot tall robot abomination."

Origins is a Zombies map included in the Apocalypse downloadable content for Call of Duty: Black Ops II. It is the seventeenth (chronologically, the first) Zombies level.

Overview
The "original characters" (Takeo, Nikolai, Richtofen and Dempsey) return as the four playable characters. The  z ombies have the classic orange eyes. The map features Wonder Weapons that harness supernatural powers, a diesel-drone and Mark IV tank, as well a new Perk-a-Cola machine and Power-Ups.

The Demonic Announcer is neither Richtofen nor Samantha. This is due to Richtofen being a playable character and Samantha's birth being years after the events of the level. It may be Dr. Maxis, the giant robot(s), the person who created the robots, or another boss zombie.

Trivia

 * The group appears to be younger, due this being their first chronological appearance.
 * This would also prove the original characters are perhaps much older than some originally thought (being at least 45-50 years old in World at War).
 * This is the first, and so far only, time the Original Group have made a visual appearance in Call of Duty: Black Ops II.
 * This is the third time the player(s) can ride in a vehicle in Zombies; the first time being in Green Run and the second being in Mob of the Dead.
 * Origins marks the first ever Call of Duty feature to take place during the First World War.
 * This also makes the level the earliest-set feature in Call of Duty history, with the previous earliest-set feature taking place in the 1930s.
