Since late September, X has been flooded with "impossible" mashups: MW2 with skateboarding, Minecraft meets Call of Duty, Vampire Survivors inside World of Warcraft, and now Sonic Adventure inside GTA V. Here's who's making them and how.
Sonic, Tails and Knuckles are all playable in Los Santos. About 30.6k likes and 1.2M views. No public download yet.

Universal-modder again. Each agent leaves notes on what broke for the next one.

Heads up: crypto tokens have sprung up around the mashup trend. CRT Forge doesn't endorse or link to any token.
Try it yourself: mod sm64coopdx with its Lua API or build scenes with Blender MCP. Then generate props with Meshy inside Blender MCP. 2D mods often need sprite cleanup — Aseprite MCP for beginners covers that agent loop.
Agent-driven engines: wire Unity MCP or Godot AI and let the model edit the scene.
A mod that combines two games, such as skateboarding in Modern Warfare 2, built with help from AI coding agents.
Usually not. Commentators on X note that most aren't the 'passthrough' method of running two games side by side. Check each project.
Modding games you own is common, but publishers have sent takedowns over AI decomp projects. Don't distribute copyrighted game files.
