The Gates of Hell
This is another base defense mission. You'll want to get bunkers and siege tanks up right away, along with extra bunkers, factories, and starports to produce new troops. The Dominion will send eight drop pods down, but you'll need to rescue them to add these forces to your army. They not only have offensive units, but sometimes buildings you can move to your base.
Sometimes, two pods will drop at once. It is incredibly difficult to rescue both at the same time, so it's much more tactical to send most of your forces to just one. Any time the Zerg launch a Nydus worm, be aggressive and destroy it right away. A worm will simply continue to pump out wave after wave of enemies, making it a giant nuisance if left alone.
After the final Dominion drop, Warfield and his squad will land in a hostile Zerg patch. Rally your whole army with a mix of tanks, thors, marines, banshees, battlecruisers, vikings, medivacs and any thing else and charge towards the general. Make your initial wave a control group and your buildings their own groups. Set rally points to the frontlines and continue to produces reinforcements while your first wave makes their way to Warfield. When the last Zerg is dealt with, Warfield will be save and the mission will conclude.
