Modding

If you want to add support for that cvar to any custom map, it is easy!

Open the map script and just add the following triggers to the script:

//ETQWPro skip entire first obj
	if(es_skipMCP.getFloatValue() > 1 && !es_vanillaMode.getBoolValue() ) 
	 { 
	  //skip entire first obj. routine
	 }
