Hello,
I'm quite new here, so let me know when I'm doing something wrong
I created a tutorial for that, how to start coding without a map like in Black Ops 1 or older Cods, one tutorial for mp and one for zm.



I'm not sure if I'm allowed to post these links here, just message me if not

I hope this answers your question, happy modding!

Best regards,
CabCon!
