I am a student and my group decided to make a racing game

I need a  source  code game for refrensi

If you know please tell me 

I really need it

Wrong forum, moving to For Beginners.

You're most likely going to want to give more details about what and how you have to make this software, what sort of racing game you have in mind, and why you chose this project when you apparently have no idea how to start it without copying someone else's code.

Ya I would like to know more about the details.
