AI Merge Games: How People Are Merging Video Games With AI

Updated 2026-10-08

"AI merge games" refers to a trend that took off in late September 2026: modders use AI coding assistants to combine two existing video games into one playable mashup – skateboarding in Call of Duty: Modern Warfare 2, Minecraft running inside Elden Ring, Escape from Tarkov's guns in Skyrim. The AI helps reverse-engineer how each game works and writes the glue code that lets features from one game run inside the other. The clips went viral on X, TikTok, Reddit and YouTube, and gaming sites started covering it in early October.

The same phrase is also used for something older and simpler: browser "merge" games such as Infinite Craft, where you combine elements and an AI invents the result. Both are covered below.

What is AI video game merging?

In the viral version, a creator takes two games – usually PC games with an active modding scene – and asks an AI coding tool to help make them compatible. That means working out how the games load assets, handle movement and animation, and process input, then writing code that pulls one game's mechanics or content into the other. The result is shown as a short gameplay clip: a character from one game moving with another game's controls, or a whole game world placed inside another.

Know Your Meme, which documented the trend on October 6, 2026, describes it as people using AI programs – most often Anthropic's Claude Opus 5.5, released September 22 – to rewrite and reverse-engineer game code until the two games can run together. Some creators also credit OpenAI's Codex.

Timeline of the trend

Date (2026) What happened
Sept 19 X user @chasmmmmmmmmmmm posts that they rewrote Skate 3 in the Rust programming language with a "human-and-AI development loop", using Codex to reverse-engineer the game.
Sept 27 The same account posts skateboarding inside Call of Duty: Modern Warfare 2 – tens of thousands of likes in a week.
Sept 28 A YouTube video of Call of Duty merged with Minecraft follows.
Sept 29 @TobynJacobs shares Minecraft running as a mod inside Elden Ring; it is reposted to r/singularity.
Sept 30 @cydonix shows Escape from Tarkov merged into Skyrim ("Escape from Skyrim"); Chasm's video "Modding has Changed FOREVER…" passes millions of views.
Oct 3 A Super Mario 64 × Elden Ring mashup by @Deltaroo3D spreads widely before being taken down after a copyright claim.

How do people merge games with AI?

There is no one-click "merge two games" app behind these clips. The examples come from experienced modders working with AI coding assistants. Based on what creators have described publicly, the workflow looks like this:

  1. Pick games with an existing modding toolchain. PC games with community tools for extracting assets and injecting code are far easier than consoles.
  2. Use the AI to understand the code. The assistant reads decompiled code, file formats and engine behavior and explains how movement, animation or rendering works.
  3. Write the bridge. The AI drafts code that loads one game's assets or logic inside the other, or reimplements a mechanic (like skateboarding physics) in the host game.
  4. Iterate. Most of the time goes into fixing crashes and tuning behavior, with the human deciding what "right" looks like.

Because this relies on reverse engineering other companies' games, merged builds are generally shared as videos rather than downloads – and as the Mario × Elden Ring takedown shows, rights holders can and do file claims.

Can I play AI merged games?

Mostly no, at least not the viral mashups: they are personal mod projects, and many depend on owning both original games. What you can play right now are:

  • Element-merging browser games such as Infinite Craft and similar "infinite alchemy" games, where you drag two words together and an AI decides what they combine into.
  • Merge games built with AI on itch.io – the platform has a tag for AI-generated games that also carry the "merge" tag.
  • Games vibe-coded with AI from scratch, which are a growing category on indie platforms.

If your goal is to make something similar yourself, start small: an original browser game built with an AI coding assistant, rather than combining commercial games you don't own the rights to.

Is it legal to merge games with AI?

Using AI doesn't change the underlying rules of modding. Many publishers tolerate mods for personal use, but distributing their code or assets, or combining two companies' games into a downloadable product, can infringe copyright and break end-user license agreements. The October 3 takedown is a reminder that viral attention brings enforcement. This article is not legal advice; check each game's modding policy.

Why the trend matters

For players it's a novelty – "what if Minecraft were inside Elden Ring" clips are fun to watch. For the industry it's a sign of how far AI coding assistants have come: tasks that used to take a skilled modding team months, like reimplementing a game's movement system, are now attempted by individuals in days. Commentators have framed it both as the future of game preservation and as a new headache for publishers protecting their IP.

FAQ

What does "AI merge games" mean?

It usually means the late-2026 trend of using AI coding tools to combine two existing video games into one mashup. It can also mean browser merge games where an AI decides what two combined items become.

Which AI is used to merge games?

Creators most often mention Anthropic's Claude Opus 5.5 and OpenAI's Codex. Neither offers a dedicated "merge games" feature – they are general coding assistants.

Which games have been merged with AI?

Widely shared examples include Skate in Call of Duty: Modern Warfare 2, Call of Duty with Minecraft, Minecraft in Elden Ring, Escape from Tarkov in Skyrim and Super Mario 64 in Elden Ring.

Can I download AI merged games?

The viral mashups are generally not released as downloads, and sharing them could infringe the original games' rights. Browser games like Infinite Craft are free to play.

When did the AI game merging trend start?

The earliest widely shared example dates to September 19, 2026, and the trend peaked in late September and early October 2026.
