# 3,500 lines of 3D game logic from a single Grok 3 session

Long-horizon tool use on XForce — where Grok 3 held and where it didn't.

The latest AI generated 3D game I made with @Grok 3 is mind-blowing! No other model can handle over 3,500 lines of complex game logic like Grok 3 from @xAI. Try the Xforce game—link below 👇

It all started with a basic 3D world from my previous Grok AI generated game that @elonmusk posted about.

It then evolved into navigating a tube game or a path, which worked well.

After that, I asked Grok 3 to make a pod travel on a line in space with first-person view and other cameras to debug it.

Then I started experimenting with other features and challenging Grok 3 AI model and push its limits

For some of the voices, I started a conversation with Grok Voice "Era" and said I wanted voices for my 3D space game. I recorded the sound from the Grok app to my computer's microphone which gave it a cool radio sound.
