Tips
Give it a shot anyway. Four days with agents on your side is a great way to try something you’d never have time for otherwise. Even if you don’t finish, you’ll learn a lot.
Find teammates or ask questions on the Unreal Engine Forums and UEFN Discord.
Do I have to use AI?
No.
Can I start before November 12?
You can set up your tools, agents, and MCP ahead of time, but don't start building your game until November 12. Declare any prompts, scripts, or assets you made before the jam.
Can my team enter with both Unreal Engine and UEFN?
No. Each team picks one and follows that submission process.
Do I need to come to San Francisco?
No. Online and in-person entries are judged the same way.
Can I keep working on my game after the jam?
Yes. Keep the jam version as your submitted build. Standout Unreal Engine and UEFN entries can also receive Development Continuation Grants of up to $50,000 to keep developing their game.
Who owns my game?
You do. See the Official Rules.
