well you know the first steps.....so i'm gonna skip to the part where you actually build stuff....for your first pylon, build it right beside your nexus....after that, build 5 probes, and when you have enough money, build defence at your entrance...build at least 20 canons...this wil last you for the whole game and if they rush...
then after that, build right accross your mineral patches like shown below
m=minerals, p=pylons, g=gateways
mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
ppppppppppppppppppppppppppppppppppppppppppppppppppppppp
ggggggggggggggggggggggggggggggggggggggggggggggggggggggg
yes build so many gateeways that your whoel base is covered up...right when you have at least 10 gateways, get a cybercore, and then start maxing out your goons, while your maxing out, upgrade and attack when your done upgrading at l;east 2 levels of everything. when attacking, what i do is make 2 arbiters with recall, i go from the 2 sides of their base with 12 goons each recall and the rest of my goons from their front entrance, i have ALWAYS won with this stradegy, if you do it fast enough, they wont' have defence all over their sides of their base so when you recall, they wil die FOR SURE!!
p.s. this stradegy works best with new perfect hunters
HAVE FUN!!

CreepColony's Opinion: Will only work for a few maps.
