AI Video Game Mod Mashups Are Taking Off—Here Are the Wackiest Examples

In brief

• Video game modders are combining classic games to create fun, weird, and wacky mashups that are going viral on social media.
• Gamers are fighting bosses in Elden Ring with Minecraft swords, skateboarding around Call of Duty maps, and swinging around Gotham City as Spider-Man.
• It's made possible through the use of Claude-based AI agents that help users to vibe code mod mashups in a matter of hours.

Social media has exploded with wacky video game mods that combine titles the public never thought they'd see together. People are driving Mario Kart vehicles in Call of Duty Zombies, fighting Elden Ring bosses with Minecraft characters, and even swinging around Batman's Gotham City as Spider-Man.

This is all possible thanks to gamers using Claude AI agents to vibe code the mods from the ground up. Merging games uses a "passthrough mod," according to a popular GitHub guide, which runs the two games simultaneously, with one hosting the world while the other supplies the gameplay—i.e., movement and combat.

Vibe coding requires the user to tell the AI model what they want, test the outcomes, and provide feedback—leaving the AI model to do all the coding itself. The GitHub guide claims it took three to four hours to merge Elden Ring and Spider-Man, although it warned that first results are often rough around the edges.
