A comment on A playable DOOM MCP app.

The title is misleading. This is in ChatGPT but not on ChatGPT. It's not running on AI. It's running on a site that serves an AI chatbot.

Still very cool though.

I suppose most people don't know this, but you can render web resources into chat harnesses via MCP apps [1]. The actual DOOM part of this runs on [2].

Ok, we've switched the title above to a hopefully-clearer phrase from the article's first sentence.

Works for me! Thanks for updating.

Title changed from “DOOM runs in ChatGPT and Claude” to “A playable DOOM MCP app”.
