Mission objectives: Destroy protoss force.
All zerg buildings must survive.
Kerrigan must survive.
In this mission the first thing you need to do is start mineral gathering operations. the second and most important thing that you need to do is make a strong defense. that means, placing Bunkers, with four marines in them, at every enterance to your base. Put missle turrents by the bunkers, keep repairing both of those. Place missle turrents all around you base to protect against air attacks. Once you have done this start moving your way up the tech tree. When you have about one thousand minerals and some marines and a few stronger units gop out through the right exit from your base. Keep going right until you come to a mineral patch. Make a base here with the same defense. It is key that at both of your command centers you make the add-on Nuclear Silo. Once you have two armed Nukes and some ghosts with cloaking ability start building up an attack force of twelve Siege Tanks with Siege Mode, Twelve Goliathes, an four to six SCV's. Be nuking the protoss while you are doing this. I suggest that you nuke the protoss base on the bottom of the map first and then move your forces in to finish it off, bewar though because the Photon Cannons are also Detectors like Missle Turrents. Keep doing this while repairing any defense that may be attacked. finish off that protoss base and then take out the one to the left of your first base the same way. (NOTE: if you need more minerals make a base where you took out the first protoss base.) Once all protoss bases have been destroyed you win the mission.
