I recently came back to the idea of making my own zombies experience, maybe as a mod for bo3 that completely overhauls the game rather than a whole new game completely. It would have a set of six maps that follows a new story outside of the aether or chaos storyline. It follows a group that first starts with their exploration of an abandoned school that was repurposed as an illegal lab for scientists during a break in the apocalypse. As of the time of their exploration, it had been years since an undead had been seen. The lab was used to figure out a way to cure the disease of the apocalypse, but later became an attempt at using the undead to access other realms. They created a device after one scientist had visions of it, but before they could test it, they were overrun with the undead.
The group in the intro of the map (Adskaya Shkola) come across the device that, after interacting and shattering it, unleashes the souls of the damned, and creating a breach from hell. The map starts off with the group split into two similar to verrückt. A voice on round 2 speaks to them, promising a way out. After providing an item to the main lab/office area. The voice promises a way to improve their odds woth the pack a punch, but states he doesnt want to make it easy, treating this as a game. The crew must complete a quest that they believe is only connected to the pap. This style of quests that seem to be used strictly to aid the players, is soon discovered to be steps to create a way for the voice to have access over the entire realm, creating a breach to hell. At the end, after completing the EE/main quest, the sky cracks open, turning everything into a hellscape, and the voice, as promised, grants the crew a way out by opening the ground below them, and dropping them into hell.
The next map (Zemlya Korolevy) intro opens with the crew falling and being saved by another entity, dropping the crew off in 1900s Moscow, in a realm that was overwhelmed by the "darkness" the voice from before plays along, and rips the ground, lifting the area into the sky. The entity speaks to them, only heard by the crew, and tells them about a way to fix what they had done. Eventually, the crew finds the object that the scientists had attempted to recreate, and after a boss fight, the helpful entity rips them from the realm, and drops them into another, Purgatory Point.
The crew are dropped off into a version of the Purgatory Point town from buried before it was transported through the temporal rift. The voice from hell and the undead follows them. The crew eventually build the agarthan device and create the PAP machine which transports everyone to a buried version of the map. In this one, certain perks like vulture aid become available. But they can also use rifts around the map to travel back to the original town. I havent got all the specifics for this and the rest of the maps made yet, but after this, they are transported to the next map which i have yet to name.
This map is set in a realm with magical beasts in the middle of a jungle. This is inspired by the temples from Angkor, Cambodia with the trees over growing the temples in the map. Again, after completing the quest in this, they are sent to the next map, ᛚᚨᚾᛞ ᛟᚠ ᚷᛟᛞᛊ, Elder Futhark for Land of Gods
The map is set in the tenth century in a realm where Norse Mythology was real. Opening with the crew on a viking long ship that is soon attacked by Jörmungandr, sending them crashing into an island that has changing weather based on four different Norse Gods. The players do not start with a pistol, instead they choose one of the four melee weapons they spawn near. A trident, a hammer, a battle axe, and a sword. These weapons are actually the wonderweapons of the map, but at this state, ghey act only as simple melee weapons. These can all be upgraded to become the wonder weapons
The trident becomes imbued with ice and water powers
The hammer becomes imbued with the power of earth
The axe becomes imbued with lightning
And the sword with fire.
After defeating Jörmungandr, the crew is sent to the last map which i have not yet made.
The idea is that every map will have one perk that is map specific, one perk that does not exist on it. And a perk that has a map specific upgrade.
