I believe it's this code:
matchStartTimer_Internal( countTime, matchStartTimer )
waittillframeend; // wait till cleanup of previous start timer if multiple happen at once
visionSetNaked( "mpIntro", 0 );
I don't really know the exact code but i believe it's spread out all throughout gamelogic.gsc and playerlogic.gsc and any code having to do with
has to do with the timer
