Below is a little history on Origins found at http://callofduty.wikia.com/wiki/Origins :
The "original characters" (Dempsey, Nikolai, Richtofen, and Takeo) once again appear as the four playable characters, this time as younger, alternate versions of their original selves, having large differences in their personalities. The zombies have yellow and blue eyes in this map. The map features Wonder Weapons that harness supernatural powers, a new enemy, the Panzersoldat, the Mark IV Tank, a new utility that gives a random Perk-a-Cola known as the Der Wunderfizz, and new Power-Ups. Revealed in the cinematic intro of Origins, zombies in typical crusader attire appear, but only spawn at the four entrances to The Crazy Place and the main Excavation Site in the center of the map. Unlike typical zombies, the crusader zombies have blue-violet eyes; the crusader zombies also make different noises than the normal zombies.
Six generators are found across the map, which act as replacements for the classic Power Switch, and only power the area around it. If they are all powered at once, they activate the reskinned Pack-a-Punch Machine. For the first time, the Mystery Box requires power to be used. The Generators also power perk machines, although there are only five conventional perk machines and there are no machines at Generators 2 and 6. There are no new perks, but rather a machine called Der Wunderfizz, that gives the player a random perk bottle when activated, much like the Mystery box.
The three Giant Robots: Freya, Odin, and Thor (from left to right, facing generator five from the excavation site) travel across the map in their respective "lanes" and will instantly down players when they step on them unless the player shoots the glowing foot or the player has a golden helmet.
There are three new power-ups:
Zombie Blood, which mask the player with zombie blood (essentially camouflage), in which they see reddish-orange, get an increased FOV, and aren't attacked by Zombies or Panzer Soldats for a short time.
Blood Money, which are obtained using the Shovel on graves (dig spots). Blood Money is similar to Bonus Points, as it gives the player a random amount of points when collected.
The Empty Perk Bottle, which can be found by digging up special dig spots around the map. Upon collecting the power-up, the player that picked it up will gain an extra perk slot, and will then be able to purchase an additional perk.
Buildables also return, featuring four Elemental Staffs (the Staff of Lightning, the Staff of Fire, the Staff of Ice, and the Staff of Wind), the Zombie Shield with a new dieselpunk aesthetic and the Maxis Drone, which is similar to the MQ-27 Dragonfire, only using Dr. Maxis' brain. The Maxis Drone, after deployed, will follow the player, shooting at Zombies and reviving downed players, it also must recharge and be picked up again after each use.
Players can also use shovels at certain spots to dig up certain items. These may hold beneficial items, like a weapon, Power-Up, or staff part. They may also spawn something hazardous, like a Zombie or a live grenade.
The Demonic Announcer for this map is Samantha Maxis, who has a different announcing voice than she did in previous maps.
