Strategy
Your biggest enemy in this one is Vespene gas. You will need to expand after the first zergling rush as soon as you can. Get as many harvesters going while building minimal forces in the beginning, just enough to hold off the attacks. If you supply depot to the North of the expansion and put bunkers behind it that will hold them off pretty well with minimal forces. Get up at all 4 Vespene Gas refineries and ensure you have at least 2 SCV’s on each one. You will probably run out of gas still without 3 on each, but you won’t have a chance without at least 2 on each one.
Once you establish your SCV harvesting economy and get extra resources. Put up the Ghost Academy, build 2 Factories, and make a total of 4 Barracks. With 2 of the Barracks put on Tech Lab, on the other two put a Reactor on to build double units. Build tanks nonstop to 8, build ghosts until you hit 8, and build double marines from the two barracks with reactors and when the Ghosts finish build from those if you have to in order to get the Gold Achievement, watch the video to see how it’s done.
