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

Gamers are using Claude-based AI agents to vibe code "passthrough mods" that merge separate video games, producing viral mashups such as Skate inside Call of Duty: Modern Warfare 2 and Minecraft inside Elden Ring, according to a GitHub guide by trevaintdead. The guide claims merging Elden Ring and Spider-Man took three to four hours, though it warned first results are often rough, and Minecraft-in-Elden Ring creator Toby Jacobs has not released his mod publicly, saying he would need to build a Windows port because it was developed for Mac.

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 https://github.com/trevaintdead/ai-game-modding-guides/blob/main/guides/00-start-here.md 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 https://decrypt.co/311144/vibe-coding-using-ai-create-apps-games 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. Some gamers say that this is "one of the coolest things https://x.com/Enderman/status/2105113206167364073?s=20 I’ve seen in gaming in 10+ years" and that it marks https://x.com/yeeeeezos/status/2107230014882410733?s=20 the dawn of "the renaissance of gaming."

With this mod, not only can you use Minecraft weapons and teleport with an Ender Pearl, but you can access 1,600 Minecraft items, create fully functioning redstone contraptions, and even enter creative mode. That's not to mention you can spawn mobs using eggs, meaning creepers can fight Elden Ring's iconic boss Malenia for you. Bored of the Minecraft options? The mod also allows you to add in Black Ops guns, so you can quickly switch between Minecraft and Call of Duty weapons in the heat of battle. Unfortunately, its creator, Toby Jacobs, has yet to release the mod to the public. He claims https://x.com/TobynJacobs/status/2105126051676668125?s=20 to be open to the idea, but says https://x.com/TobynJacobs/status/2105132868934774840 he'll have to create a Windows port as it was developed for Mac.
