The intro cutscene of Origins uploaded on Treyarch's YouTube channel was taken down and re-uploaded later to correct Nikolai Belinski's name being misspelled as "Nikolai Belinksi".
An official poster of Origins was released, created by Alex Ross.
Originally, the intro cutscene featured Samantha with a hollow and ghastly voice. In the game however, she sounds a lot clearer akin to a little girl. More dialogue was also added in the final version.
When activating a generator while Double Points is active, the player who activated the generator only gets refunded half their points. This does not affect solo gameplay, however, as the 100 points earned for activating the generator before the refund are doubled, resulting in the same 300 total points (provided the player stays on the generator until all points are given).
Parts of the church roof can be destroyed and collapsed using explosives, killing zombies and also downing players in its path.
There are four robots in the map. Three circle around and make passes through the map, and another one was shot down near the Tank Station at Generator 2.
The Medieval Zombie on the poster is wearing the Cross of the Knights Templar.
The Medieval Zombies on the poster have yellow eyes, even though they have purple-white eyes in-game.
The player can go prone in front of a Perk-a-Cola machine and get 25 points. This also works with the Pack-a-Punch machine, regardless of how many generators are activated, but does not work with the Der Wunderfizz.
Furthermore, the zombies that come out of the ground when a generator is turned on as well as the zombies that spawn in the Crazy Place wear a symbol on their outfits that is almost identical to the Black Sun occult symbol.
While in the Crazy Place, if the player has not yet collected any of the elemental gems, the large walls that drop and block random paths will not fall down, allowing uninterrupted access to the large room.
The three Giant Robots (Freya, Odin, and Thor) share their names with the three Norse gods.
Some Pack-a-Punch weapons, such as the Boomhilda, and the upgraded staffs also make reference to different mythologies.
Carpenter was also going to be featured in the map, but was removed in the final version. It makes an appearance in the remastered version in Zombies Chronicles, however.
The robot that attempts to step on the players in the opening cinematic is the robot Thor.
In the opening transcript, the robot has its foot lit yellow, indicating that the player can shoot the foot to get inside the robot's head. However, at the beginning of the game the foot will not always be lit.
It is possible to spawn an inaccessible Power-Up at the edge of the roof of the Tank Station.
For unknown reasons, the PC version of the map lacks shirtless variant of German zombies.
On DLC pack logo of the map, a few British/American soldiers can be seen. However, they do not make an appearance in the map nor the cutscenes.
In the remastered version there are a set of papers in a morter crater along the tank path, between Generator 5 and Generator 2. These papers have lists of names on them that are those of workers at Treyarch. Some names include Jason Blundell, Max Porter and Kevin Sherwood.
