What are some interesting plot ideas for Call of Duty Zombies fanfiction?

A good plot idea could be that your OC discovers a hidden underground facility that holds the key to stopping the zombie outbreak. Another idea is that they get trapped on a zombie - infested island and have to find a way to signal for help while surviving the hordes. Or perhaps they team up with a group of unlikely allies, like a zombie who still has some human consciousness and they have to work together to end the apocalypse.

One possible plot could be that Naruto and his friends are transported into the Call of Duty Zombies universe. They have to use their ninja skills to survive against the hordes of zombies. Naruto could use his shadow clones to distract the zombies while Sasuke uses his Sharingan to find weak points in the zombies' defenses.

Another plot could involve a character traveling forward in time. Maybe a World War II veteran suddenly finds himself in the middle of a high - tech, futuristic battle. He'd be in awe of the advanced weaponry and the different combat styles. He could then use his old - fashioned values and combat experience to inspire the modern soldiers.

One idea could be exploring the backstories of the minor characters more in - depth. For example, the soldiers who are part of the squad but don't have much screen time in the game. Another could be creating an alternate ending where the events of the game take a different turn, like the main villain actually succeeding in their initial plan but then the heroes have to find a new way to reverse it. And a third idea might be to write a fanfiction from the perspective of the enemy forces, showing their motives and what they think during the battles.

One idea could be an OC who is a former Ghost turned rogue and now the Ghosts have to hunt them down. This could add a lot of moral complexity to the story.

One idea could be Harry Potter characters being transported into the Call of Duty universe and having to use their magic in the middle of a modern warfare scenario. For example, Hermione might use spells to hack into enemy communication systems.

One interesting storyline could be about a group of survivors who find a mysterious lemon - shaped artifact in the Zombies mode. This artifact gives them special powers to fight off the zombies more effectively. They have to protect it while also dealing with the hordes.

One idea could be creating an OC (Original Character) who is a sniper with a troubled past. Maybe they were once a part of a special forces unit but got betrayed. Another idea is an OC that is a female medic in a male - dominated warzone, facing discrimination and proving herself. A third idea could be an OC that discovers a hidden conspiracy within the military hierarchy of the Call of Duty universe.

One idea could be to have the soldiers from Call of Duty end up in the RWBY universe. They could be shocked by the Grimm and then team up with the RWBY characters to fight against them. Another idea is a crossover where RWBY characters use Call of Duty - style weapons. For example, Ruby could use a high - tech sniper rifle like in Call of Duty.

One plot idea could be Logan and Keegan getting separated during a mission in a war - torn city. Logan has to fight his way through enemy lines to find Keegan who is trapped and injured. Another could be a prequel - style story where they first meet during their training days and start to form their unbreakable bond.
