They definitely improved the Zerg in this one, they will keep on harassing and and they try to take control of the map fairly early in the game.

I was playing Zerg, and i was going up against a fellow Zerg as well.. The opposing Zerg kept on harassing me with mutas and infested, all of a sudden the zerg pulls 6 ultras and almost annihilates me but i was able to kill them. By that time, around the 10 minute mark, i was out of gas and minerals and the zerg harassed me to the point where i could not leave my base. They also expanded to most of the map. This is by far the best AI yet. Didn't yet take a look at protoss or Terran yet.   

Yeah i totally got owned by Terran while i was trying to take out a protoss base about 7 minutes into the game, totally better than any other AI file out so far.
