How to Get the "Insane Blitz" Achievement

Took me a few tries to get the exact timing and placement of this build down so I thought I would share. Here is the download replay link.


This achievement essentially involves cannon rushing either a Terran or Protoss AI. The cannon rush will only work in a map like Agria Valley where you can build cannons outside of the AI base so as to be outside of the range where the AI automatically attacks buildings. If you try to build anything inside of this range (which is roughly the size of its base floor) it will immediately spot you and attack.
