This can be achieved in Ranked Multiplayer or Skirmish. It cannot be achieved in private matches or if a player quits; the game must be played to the end. There are 26 KOTH maps. To win in King of the Hill, you must accumulate points by having combat units (not your ACU) remain in the marked area (generally in the middle of the map, except on one or two small two-player maps). Points are awarded based on the number of units and their tech level. A single Tech 1 unit gives you 1 point every four seconds, and the minimum point value to win is 100,000 points. Obviously, that is not an approach that makes for a quick victory. The quickest way to win is to build an Experimental Unit which is a Tech 4, and earns about 3800 points every 4 seconds.
