How about a crossover with 'The Witcher'? Geralt of Rivia could find himself in the world of Code Vein. He would have to deal with the vampires and other creatures in Code Vein using his skills and potions. The Witcher's monster - hunting knowledge could be very useful in this new environment. And the story could explore how the Code Vein characters react to Geralt's presence.
First, you need to decide which two universes you want to cross over. For example, if it's Code Vein and 'Resident Evil', think about how the elements of the two will interact. Then, create a basic plot. Maybe the virus in Resident Evil has somehow infected the Code Vein world and the characters have to find a cure. Next, start with an interesting opening scene. It could be a character from Code Vein suddenly finding themselves in a Resident Evil - like environment.
One idea could be a Code Vein and Dark Souls crossover. The protagonist from Code Vein could find themselves in the world of Dark Souls, facing different challenges like the bonfires and the more unforgiving combat system. Another could be a crossover with Bloodborne, where the gothic horror elements blend together. Maybe the characters from Code Vein have to deal with the beasts in Bloodborne's world.
One interesting concept could be alternative character backstories. For example, creating a more detailed and tragic past for the main characters that adds more depth to their personalities. Another could be exploring different relationships between characters that weren't fully developed in the original game, like a deeper friendship or a new kind of rivalry.
Begin by getting really familiar with the characters in Code Vein. Know their personalities, abilities, and backstories. Then, think about how they would react in a different universe. If you're doing a crossover with Horizon Zero Dawn, consider how the Revenants would interact with the machines. You also need to decide on a theme for your fanfiction. Is it about survival, friendship, or something else? Once you have these elements in place, start writing a rough outline of the story, including the beginning, middle, and end.
One interesting Code Vein IO fanfic could be about the origin of the Revenants. It might explore how the first Revenants came to be in the world of Code Vein. Another could focus on the relationships between different characters, like the bond between the protagonist and their partner. There are also fanfics that might imagine alternative endings to the game's main story, giving a whole new perspective on the game's universe.
