build scv's until u have 7 once u have 7 scv's build 4 supply depots at the entrance to ur base to make impossible for most units to get in.then 2 barracks and then u build 2 refinere's with 3 at each.thenbuild 6 bunkers by the supply- depots then but the marines u should have built with those barracks in the bunkers so u will kill any rushes then build an academy to upgrade marine range then build a enginenerring bay and then build 2 fatories with machine shop attachments and research seige mode wile pumbing out seige tanks (around 12 will do) but them behind the bunkers with the seige mode witch should be done already then seige them (oh and u should have alredy been making scv's at ur own rate) then get some scv's and build missle turrets behind ur seige tanks and on the sides of ur base for air and drops maybe some science vessels for like erritate and such..... that is all of my d once u r done with that u will have lots of money to build bc's and wraiths to attack maphack might help to see what there attacking with wicth is for cheaters anyways but not for me cause i not cheat.

CreepColony's Opinion: Don't forget to put some defense inside your base too.
